Abstract
The genetic mechanisms of reproductive isolation have been widely investigated within Asian cultivated rice (Oryza sativa); however, relevant genes between diverged species have been in sighted rather less. Herein, a gene showing selfish behavior was discovered in hybrids between the distantly related rice species Oryza longistaminata and O. sativa. The selfish allele S13l in the S13 locus impaired male fertility, discriminately eliminating pollens containing the allele S13s from O. sativa in heterozygotes (S13s/S13l). Genetic analysis revealed that a gene encoding a chromatin-remodeling factor (CHR) is involved in this phenomenon and a variety of O. sativa owns the truncated gene OsCHR745, whereas its homologue OlCHR has a complete structure in O. longistaminata. CRISPR-Cas9-mediated loss of function mutants restored fertility in hybrids. African cultivated rice, which naturally lacks the OlCHR homologue, is compatible with both S13s and S13l carriers. These results suggest that OlCHR is a Killer gene, which leads to reproductive isolation.

Abstract
MAIN CONCLUSION PROG1 is necessary but insufficient for the main culm inclination while TAC1 partially takes part in it, and both genes promote tiller inclination in Asian wild rice. Asian wild rice (Oryza rufipogon), the ancestor of cultivated rice (O. sativa), has a prostrate architecture, with tillers branching from near the ground. The main culm of each plant grows upward and then tilts during the vegetative stage. Genes controlling tiller angle have been reported; however, their genetic contributions to the culm movement have not been quantified. Here, we quantified their genetic contributions to angular kinematics in the main culm and tillers. For the main culm inclination, one major QTL surrounding the PROG1 region was found. In cultivated rice, tillers firstly inclined and lately rose, while it kept inclining in wild rice. It was suggested that PROG1 affected the tiller elevation angle in the later kinematics, whereas TAC1 was weakly associated with the tiller angle in the whole vegetative stage. Micro-computed tomography (micro-CT) suggested that these angular changes are produced by the bending of culm bases. Because near-isogenic lines (NILs) of wild rice-type Prog1 and Tac1 alleles in the genetic background of cultivated rice did not show the prostrate architecture, the involvement of another gene(s) for inclination of the main culm was suggested. Our findings will not only contribute to the understanding of the morphological transition during domestication but also be used in plant breeding to precisely reproduce the ideal plant architecture by combining the effects of multiple genes.

Abstract
Low-temperature adaptation in rice is mediated by the ability of a genotype to tolerate chilling temperatures. A genetic locus on chromosome 11 was analysed for chilling tolerance at the plumule stage in rice. The tolerant allele of A58, a japonica landrace in Japan, was inherited as a recessive gene (ctp-1A58), whereas the susceptible alleles from wild rice (Ctp-1W107) and modern variety (Ctp-1HY) were the dominant genes. Another recessive tolerant allele (ctp-1Silewah) was found in a tropical japonica variety (Silewah). Fine-mapping revealed that a candidate gene for the ctp-1 locus encoded a protein similar to the nucleotide-binding domain and leucine-rich repeat (NLR) protein, in which frameshift mutation by a 73 bp-deletion might confer chilling tolerance in ctp-1A58. Analysis of near-isogenic lines demonstrated that ctp-1A58 imparted tolerance effects only at severe chilling temperatures of 0.5 °C and 2 °C, both at plumule and seedling stages. Chilling acclimation treatments at a wide range of temperatures (8 °C-16 °C) for 72 h concealed the susceptible phenotype of Ctp-1W107 and Ctp-1HY. Furthermore, short-term acclimation treatment of 12 h at 8 °C was enough to be fully acclimated. These results suggest that the NLR gene induces a susceptible response upon exposure to severe chilling stress, however, another interacting gene(s) for acclimation response could suppress the maladaptive phenotype caused by the Ctp-1 allele. This study provides new insights for the adaptation and breeding of rice in a low-temperature environment.

Abstract
The Doce River Basin (DRB) represents a well-described watershed in terms of contamination by metals, especially after a major environmental disaster of a mining tailing dam failure. Despite the massive mortality of the ichthyofauna, very few studies addressed the risks to the health of wild fish exposed to complex mixtures of pollutants from multiple sources. The present study proposed to investigate earlier responses of fish for assessing the impacts of multiple sources of pollution, considering: different niches of fish and target organs; and the influence of seasonality, associated with their probable sources of pollution. To achieve that, fish were collected along the DRB, and biomarkers responses were assessed in target organs and correlated with the levels of inorganic and organic contaminants. As one of the most prominent responses, fishes from the Upper DRB showed the highest expression of the metallothionein and oxidative stress parameters which were related to the higher levels of metals in this region due to the proximity of mining activities. On the other hand, higher levels of DNA damage and increased AChE activity from fish sampled in the Mid and Lower DRB were more associated with organic contaminants, from other sources of pollution than mining residues. The integrated biomarker responses also revealed seasonal variations, with higher values in fishes from the dry season, and pelagic fish showing greater variation within the seasons. The multivariate analysis integrating suitable biomarkers with chemical data represented an adequate strategy for assessing the ecological risks in the DRB, allowing the identification of distinct spatio-temporal impacts from multiple sources of contaminants. The continued exposure of the ichthyofauna representing future risks reinforces the need for ecological restoration and the protection of the fauna from the Doce River.

Abstract
Low or excessive soil fertility is a major constraint to potato production. The influence of each individual nutrient element on potato plants under field studies remains ambiguous due to the influence of environmental variations. Creating an in vitro model plant with deficient or excessive nutrient content will provide a more controlled study and allow for a better understanding of how the concentration of one element can affect the uptake of other elements. Here we designed a tissue culture-based nutrition control system to systematically analyze the effects of essential nutrients on potato plants. Insufficient or excessive nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) contents were created by modifying the Murashige and Skoog (MS) medium. Deficient to toxic plant nutrient statuses were successfully defined by the evaluation of dry biomass and morphological symptoms. The results showed that plant shoot growth, nutrient uptake and content, and nutrient interactions were all significantly impacted by the changes in the MS media nutrient concentrations. These tissue culture systems can be successfully used for further investigations of nutrient effects on potato production in response to biotic and abiotic stresses in vitro.

Abstract
Limitations for the application of genome editing technologies on elite wheat (Triticum aestivum L.) varieties are mainly due to the dependency on in vitro culture and regeneration capabilities. Recently, we developed an in planta particle bombardment (iPB) method which has increased process efficiency since no culture steps are required to create stably genome-edited wheat plants. Here, we report the application of the iPB method to commercially relevant Japanese elite wheat varieties. The biolistic delivery of gold particles coated with plasmids expressing CRISPR/Cas9 components designed to target TaQsd1 were bombarded into the embryos of imbibed seeds with their shoot apical meristem (SAM) exposed. Mutations in the target gene were subsequently analyzed within flag leaf tissue by using cleaved amplified polymorphic sequence (CAPS) analysis. A total of 9/358 (2.51%) of the bombarded plants (cv. "Haruyokoi," spring type) carried mutant alleles in the tissue. Due to the chimeric nature of the T0 plants, only six of them were inherited to the next (T1) generation. Genotypic analysis of the T2 plants revealed a single triple-recessive homozygous mutant of the TaQsd1 gene. Compared to wild type, the homozygous mutant exhibited a 7 days delay in the time required for 50% seed germination. The iPB method was also applied to two elite winter cultivars, "Yumechikara" and "Kitanokaori," which resulted in successful genome editing at slightly lower efficiencies as compared to "Haruyokoi." Taken together, this report demonstrates that the in planta genome editing method through SAM bombardment can be applicable to elite wheat varieties that are otherwise reluctant to callus culture.

Abstract
Abstract
Background
Air pollution is a serious problem in India. According to World Bank's data in 2015, about 660 million people were categorized as poor (US$3.20 per day per capita) in India and the proportion to total the population was 50.4 %. Even though the number and proportion are large, the effects on the poor people have not been studied very well. We measured the effects of air pollution on children of the poor and compared between urban and rural area in West Bengal, India.
Methods
24 male students (12.5 ± 0.8 years) in urban area (Kolkata) and 20 male students (12.5 ± 0.5 years) in rural area (Jata) were recruited. We measured fractional exhaled nitric oxide (FeNO), which was index of airway inflammation and checked allergic symptoms. The survey was conducted in January (dry season) and August (rainy season) 2019 to confirm a seasonal difference. Air quality index (AQI) in each area was used for index of air pollution.
Results
Average AQI was 335 (Kolkata) and 155 (Haldia: near Jata) for 2 months from December 2018 to January 2019, while average AQI was 51 (Kolkata) and 38 (Haldia) for 2 months from July to August 2019. As for FeNO in dry season, the value in Kolkata was 24.9 ± 16.1 and the value in Jata was 11.7 ± 3.5. As for FeNO in rainy season, the value in Kolkata was 22.3 ± 17.5 and the value in Jata was 16.8 ± 6.7. The value of FeNO in Kolkata was higher than Jata in either season. Although a seasonal difference was not detected in Kolkata, the value in dry season was lower than in rainy season in Jata. The prevalence of allergic symptoms in dry season was higher than in rainy season in Kolkata. On the other hand, there was no difference in the prevalence between dry and rainy season in Jata.
Conclusions
Even though AQI and the prevalence of allergic symptoms decreased, the value of FeNO did not decrease in Kolkata. Because AQI decreased, indoor air pollution might have influenced on airway. It is supposed that prevention of indoor air pollution is important.
Key messages
Airway of children in urban area may be influenced on by air pollution more than in rural area. Indoor air pollution may influence on children of the poor more than outdoor air pollution.

Abstract
Common wheat has three sets of sub-genomes, making mutations difficult to observe, especially for traits controlled by recessive genes. Here, we produced hexaploid wheat lines with loss of function of homeoalleles of Qsd1, which controls seed dormancy in barley, by Agrobacterium-mediated CRISPR/Cas9. Of the eight transformed wheat events produced, three independent events carrying multiple mutations in wheat Qsd1 homeoalleles were obtained. Notably, one line had mutations in every homeoallele. We crossed this plant with wild-type cultivar Fielder to generate a transgene-free triple-recessive mutant, as revealed by Mendelian segregation. The mutant showed a significantly longer seed dormancy period than wild-type, which may result in reduced pre-harvest sprouting of grains on spikes. PCR, southern blotting, and whole-genome shotgun sequencing revealed that this segregant lacked transgenes in its genomic sequence. This technique serves as a model for trait improvement in wheat, particularly for genetically recessive traits, based on locus information from diploid barley.

Abstract
Background
Oral or intravenous beta-blockers have commonly been used to control the heart rate (HR) prior to coronary computed tomography angiography (CCTA). However, the administration after arrival at the hospital was time-consuming, and could not achieve the target heart rate in several cases. Moreover, the efficacy of transdermal beta blockers in HR control for patients who underwent CCTA have not been fully reported.
Purpose
The purpose of this study was to clarify the usefulness of the bisoprolol patch prior to the arrival at the hospital in HR control for patients who underwent CCTA.
Methods
A total of 282 consecutive patients (160 male, age 64±12 years) who underwent CCTA were included in this study. The bisoprolol transdermal patch (8mg) was administered before arrival at the hospital in 191 patients (beta group), and no additional medication was administered in 91 patients (control group). Intravenous landiolol hydrochloride was administered when HR remained over 65 bpm on arrival at the hospital. The HR on arrival, during and after CCTA was evaluated.
Results
The baseline HR was significantly higher in the beta group (80±15 vs. 72±15, P<0.0001). However, the achievement rate of HR ≤65 bpm on arrival was significantly higher in the beta group (56.5% vs. 44.0%, P=0.047). Thus, additional treatment with intravenous landiolol hydrochloride was administered to 43.5% of the patients in the beta group and 56.0% of those in the control group. There were no significant differences in the HR during and after CCTA between the 2 groups. Multivariate analysis revealed that the use of bisoprolol transdermal patch (OR, 3.54; 95% CI 1.67–7.51, P=0.001) and the baseline HR (OR, 0.91; 95% CI 0.89–0.94, P<0.0001) were significant predictors of the achievement rate of HR ≤65 bpm on arrival. There were no serious adverse effects throughout CCTA in all patients.
Conclusions
The administration of bisoprolol transdermal patch before arrival at the hospital was useful for HR control and reduced the rate of additional intravenous treatment in patients who underwent CCTA.

Abstract
Spelt wheat (Triticum aestivum subsp. spelta), a subspecies of common wheat, is a genetic resource for the breeding of bread wheat (T. aestivum subsp. aestivum); however, genetic analyses of agronomic traits in bread wheat × spelt crosses are insufficient. Here, we conducted QTL analysis in the recombinant inbred lines from a bread wheat × spelt cross. In addition to the major Q locus, QSpd.obu-4D was detected with the spelt allele conferring a higher spikelet density than the bread wheat allele. The effect of QSpd.obu-4D was evident in the presence of the Q allele of bread wheat, suggesting that this variation might be cryptic in spelt wheat with the q allele. Two QTLs with stable effects were identified for grain length, one of which (QGl.obu-1A) has never been detected in a bread wheat × spelt cross. The spelt wheat allele at QHt.obu-7B conferring later heading was identified in the Vrn-B3 region and could be a novel gene source for modifying heading time. Furthermore, QGi.obu-2B, responsible for low grain dormancy of spelt wheat, was detected. Further exploration and identification of useful QTLs could accelerate the utilization of spelt wheat as a genetic resource for bread wheat breeding programs.

Abstract
Nafamostat mesilate (FUT-175) is a strong protease inhibitor and is used as an anticoagulant in extracorporeal circulation. In the present study, we administered FUT and dipyridamole as anticoagulants during donor plasmapheresis, and the additional effect of dipyridamole was examined. In dogs weighing about 15 Kg, donor plasmapheresis was performed using a cellulose triacetate membrane plasmaseparator (PEX-15, Nipro), and 300 ml of filtrated plasma was obtained within 30 minutes. These dogs were divided into two groups, 50 mg/h of FUT alone was infused (group A, n=10), and the same dose of FUT and 25 mg/h of dipyridamole were infused (group B, n=5) during plasmapheresis. Changes of the coagulation system, blood cell counts and complement system were investigated. In clinical cases, an artificial liver support therapy using FUT as an anticoagulant was performed on 8 patients with acute liver failure, and blood compatibility was examined. In dogs, RBC counts and hematocrits were almost stable, but WBC counts were decreased to about 70% of the previous value. Platelets counts were about 60% and 80% of the previous value, in group A and group B, respectively, at the end of the plasmapheresis (P<0.01). Clotting factor VIII was diminished to about 20% and 35% of the previous value in group A and B, respectively. In clinical cases, all patients received the plasma exchange combined with hemodialysis using FUT as an anticoagulant, and no distinct side effect was observed during plasma exchange.

Abstract
BACKGROUND Pre-harvest sprouting frequently occurs in Triticum aestivum (wheat) and Hordeum vulgare (barley) at the end of the maturity period due to high rainfall, particularly in Asian monsoon areas. Seed dormancy is a major mechanism preventing pre-harvest sprouting in these crops. RESULTS We identified orthologous sequences of the major Hordeum vulgare (barley) seed dormancy gene Qsd1 in hexaploid wheat cv. Chinese Spring by performing genomic clone sequencing, followed by transcript sequencing. We detected 13 non-synonymous amino acid substitutions among the three sub-genomes of wheat and found that the Qsd1 sequence in the B sub-genome is most similar to that in barley. The Qsd1 sequence in A genome diploid wheat is highly similar to that in the hexaploid A sub-genome. Wheat orthologs of Qsd1 showed closer similarities to barley Qsd1 than did those of other accessions in the DNA database. Like barley Qsd1, all three wheat Qsd1s showed embryo-specific gene expression patterns, indicating that barley and wheat Qsd1 share an orthologous origin. The alignment of four hexaploid wheat cultivars indicated that the amino acid sequences of three spring cultivars, Chinese Spring, Haruyo Koi, and Fielder, are exactly the same in each sub-genome. Only Kitahonami has three amino acid substitutions at the B sub-genome. CONCLUSIONS Kitahonami has a longer seed dormancy period than does Chinese Spring. Sequence polymorphisms between Chiniese Spring and Kitahonami in the B sub-genome may underlie the phenotypic differences in seed dormancy between these hexaploid wheat cultivars.

Abstract
Aims The aim of this study was to assess hypertrophy of the extra-articular tendon of the long head of biceps (LHB) in patients with a rotator cuff tear. Patients and Methods The study involved 638 shoulders in 334 patients (175 men, 159 women, mean age 62.6 years; 25 to 81) with unilateral symptomatic rotator cuff tears. The cross-sectional area (CSA) of the LHB tendon in the bicipital groove was measured pre-operatively in both shoulders using ultrasound. There were 154 asymptomatic rotator cuff tears in the contralateral shoulder. Comparisons were made between those with a symptomatic tear, an asymptomatic tear and those with no rotator cuff tear. In the affected shoulders, the CSAs were compared in relation to the location and size of the rotator cuff tear. Results The mean CSA was 21.0 mm2 (4 to 71) in those with a symptomatic rotator cuff tear, 19.9 mm2 (4 to 75) in those with an asymptomatic rotator cuff tear and 14.1 mm2 (5 to 43) in those with no rotator cuff tear. The mean CSA in patients with both symptomatic and asymptomatic rotator cuff tears was significantly larger than in those with no rotator cuff tear (p < 0.001). In the affected shoulders, there were significant differences between patients with more than a medium sized posterosuperior cuff tear and those with an antero-superior cuff tear. Conclusion Regardless of the symptoms, there was significant hypertrophy of the extra-articular LHB tendon in patients with a rotator cuff tear. The values were significantly related to the size of the tear. Cite this article: Bone Joint J 2017;99-B:806–11.

Abstract
Pre-harvest sprouting (PHS) is one of the serious problems for wheat production, especially in rainy regions. Although seed dormancy is the most critical trait for PHS resistance, the control of heading time should also be considered to prevent seed maturation during unfavorable conditions. In addition, awning is known to enhance water absorption by the spike, causing PHS. In this study, we conducted QTL analysis for three PHS resistant related traits, seed dormancy, heading time and awn length, by using recombinant inbred lines from 'Zenkouji-komugi' (high PHS resistance) × 'Chinese Spring' (weak PHS resistance). QTLs for seed dormancy were detected on chromosomes 1B (QDor-1B) and 4A (QDor-4A), in addition to a QTL on chromosome 3A, which was recently cloned as TaMFT-3A. In addition, the accumulation of the QTLs and their epistatic interactions contributed significantly to a higher level of dormancy. QDor-4A is co-located with the Hooded locus for awn development. Furthermore, an effective QTL, which confers early heading by the Zenkouji-komugi allele, was detected on the short arm of chromosome 7B, where the Vrn-B3 locus is located. Understanding the genetic architecture of traits associated with PHS resistance will facilitate the marker assisted selection to breed new varieties with higher PHS resistance.

Tissue specimens from 82 cases of surgically-treated pituitary adenomas were immunostained for hormone production for the MIB-1 LI and for the three NOS isoenzymes and five normal pituitary glands were immunostained for the three NOS isoenzymes as a control. The correlation between the clinical variables (age, functional status, tumor size, Hardy's grading, cavernous and/or sphenoid invasiveness, and progression) and mean MIB-1 LI, or between the same clinical variables and NOS immunoreactivity (IR) were analyzed. There was a statistically significant difference in the MIB-1 LI between macroadenomas and microadenomas, and between invasive adenomas and noninvasive adenomas. On the other hand, there was a statistically significant difference in the inducible NOS (iNOS) IR between invasive adenomas and noninvasive adenomas. Furthermore, the iNOS IR had a significant correlation with the MIB-1 LI. Invasive adenomas have a higher iNOS IR, and this correlated with the MIB-1 LI. These findings may be due to the function of iNOS, which plays an important role in tissue injury and repair.

Abstract
The purpose of this study was to compare the language and cognitive profiles of four progressive nonfluent aphasia (PNFA) patients with 25 probable Alzheimer's disease (pAD) patients, and to identify the distinct cortical defects associated with cognitive deficits in PNFA using positron emission tomography (PET). Longitudinal observations of PNFA patients revealed progressively telegraphic speech and writing and a gradual deterioration of sentence comprehension, but memory and visual functioning were relatively preserved. Direct contrast with PAD patients revealed that PNFA patients are significantly impaired on grammatical phrase structure aspects of sentence comprehension and expression, phonemic judgments, repetition, and digit span, but not on other cognitive measures. PET studies of PNFA revealed reduced cortical activity throughout the left hemisphere. In addition, there was a prominent defect in left superior and middle temporal and inferior frontal regions of PNFA patients that differed significantly from the distribution of regional cerebral dysfunction in pAD. We conclude that PNFA is associated with a distinct profile of language and cognitive difficulty, and that this pattern of impairment is related to cortical dysfunction in a specific distribution of the left hemisphere.

Abstract
In this study, we introduce a real-time method for tongue movement estimation based on the analysis of the surface electromyography (EMG) signals from the suprahyoid muscles, which usual function is to open the mouth and to control the position of the hyoid, the base of the tongue. Nine surface electrodes were affixed to the underside of the jaw and their signals were processed via multi-channel EMG system. The features of the EMG signals were extracted by using a root mean square (RMS) method. The dimension of the variables was reduced additionally from 108 to 10 by applying the Principal Component Analysis (PCA). The feature quantities of the reduced dimension set were associated with the tongue movements by using an artificial neural network. Results showed that the proposed method allows precise estimation of the tongue movements. For the test data set, the identification rate was greater than 97 % and the response time was less than 0.7 s. The proposed method could be implemented to facilitate novel approaches for alternative communication and control of assistive technology for supporting the independent living of people with severe quadriplegia.

Abstract
In this study, we have investigated the performance of liquid-environment FM-AFM with various cantilevers having different dimensions from theoretical and experimental aspects. The results show that reduction of the cantilever dimensions provides improvement in the minimum detectable force as long as the tip height is sufficiently long compared with the width of the cantilever. However, we also found two important issues to be overcome to achieve this theoretically expected performance. The stable photothermal excitation of a small cantilever requires much higher pointing stability of the exciting laser beam than that for a long cantilever. We present a way to satisfy this stringent requirement using a temperature controlled laser diode module and a polarization-maintaining optical fiber. Another issue is associated with the tip. While a small carbon tip formed by electron beam deposition (EBD) is desirable for small cantilevers, we found that an EBD tip is not suitable for atomic-scale applications due to the weak tip-sample interaction. Here we show that the tip-sample interaction can be greatly enhanced by coating the tip with Si. With these improvements, we demonstrate atomic-resolution imaging of mica in liquid using a small cantilever with a megahertz-order resonance frequency. In addition, we experimentally demonstrate the improvement in the minimum detectable force obtained by the small cantilever in measurements of oscillatory hydration forces.

Abstract
We characterized a spontaneous dwarf mutant showing extremely short internodes and dark green leaves originating from azuki bean (Vigna angularis (Willd.) Ohwi & Ohashi) cultivar "Erimo-shouzu." F(1) plants of 3 cross combinations between the dwarf mutant and several representative wild-type plants, Erimo-shouzu, V. angularis accession Acc2265 and wild relative V. riukiuensis accession Acc2482, supported the dwarf genotype being recessive. In a total of 3328 F(2) progeny of these 3 crosses, 65 dwarfs (2.0%) and 5 chimeric dwarfs (0.2%) segregated and the remainder were wild-type plants (97.8%). In F(3) progeny derived from self-pollinated dwarf F(2) plants, we observed wild type (54.3%), dwarf (39.1%), and chimeric dwarf (6.5%) plants. Two types of chimeric plants were observed: dwarf branches on the axils of wild-type plant stems and wild-type branches on the axils of dwarf stems. In 21 dwarf F(2) plants, the dwarf trait cosegregated with simple sequence repeat marker CEDG154 on chromosome 4. Conversely, homozygote F(2) plants at this chromosomal segment from the dwarf mutant frequently (>90%) expressed the wild-type phenotype. We concluded that the dwarf phenotype is mitotically and meiotically inheritable and controlled by a single genetically unstable locus, designated Azuki Dwarf1 (AD1), which converts between 2 phenotypic states bidirectionally.

Abstract
A dwarfing gene (allele) sd1-d has been intensively utilized to develop short-culm indica varieties in southeast Asia up to now. Before the first sd1-d-carrying variety IR8 was released, rice researchers had recognized the general tendency that culm length is higher in indica varieties than in temperate-japonica ones. Inter-subspecific difference of the tall (wild-type) allele SD1 at the sd1 locus was examined on the common genetic background, using five isogenic lines developed by substituting sd1-d of the recurrent parent IR36 by SD1s of two indica varieties, two temperate-japonica varieties and one tropical-japonica variety. The two indica -donor isogenic lines had longer culms than the three japonica-donor isogenic lines consistently in two different environmental conditions. Moreover, nonsynonymous single-nucleotide polymorphism between the two subspecies was detected at two sites in Exon 1 and Exon 3 of the sd1 locus. It is demonstrated that the inter-subspecific differentiation of SD1 contributes height difference between indica and japonica. The indica-originating and japonica-originating alleles at the sd1 locus were designated as SD1-in(t) and SD1-ja(t), respectively.

Abstract
Phenotypic plasticity is an adaptive mechanism adopted by plants in response to environmental heterogeneity. Cultivated and wild species adapt in contrasting environments; however, it is not well understood how genetic changes responsible for phenotypic plasticity were involved in crop evolution. We investigated the genetic control of phenotypic plasticity in Asian cultivated ( Oryza sativa ) and wild rice ( O. rufipogon ) under 5 environmental conditions (2 nutrient and 3 density levels). Quantitative trait locus (QTL) analysis was conducted for traits affecting plant architecture and biomass production. By analysing the phenotypic means, QTLs of large effects were detected as a cluster on chromosome 7 under all the environmental conditions investigated; this might have contributed to transitions of plant architecture during domestication, as reported previously. Multiple QTLs of plasticity were also found within this QTL cluster, demonstrating that allele-specific environmental sensitivity might control plasticity. Furthermore, QTLs controlling plasticity without affecting phenotypic means were also identified. The mode of action and direction of allele effects of plasticity QTLs varied depending on the traits and environmental signals. These findings confirmed that cultivated and wild rice show distinctive genetic differentiation for phenotypic plasticity, which might have contributed to adaptation under contrasting environmental heterogeneity during the domestication of rice.

Abstract
The McGill Quality of Life Questionnaire (MQOL), which consists of 16 items constructing physical, psychological, existential and support subscales and one item of overall quality of life (QOL), has been developed to assess QOL of terminal cancer patients. To examine if MQOL Japanese version (MQOL-J) is applicable, it was administered to 83 terminal cancer patients in palliative care wards several days after admission and then 7 to 10 days after the first interview. Cronbach's alpha coefficient for four subscales was 0.584-0.860. Sixteen items were classified into four factors by factor analysis, similar to the original English version. The results indicated that psychological and existential domains of the MQOL-J significantly related to overall QOL. Existential and support domains as well as overall QOL were significantly improved between the first and second interviews, although performance status assessed by Eastern Cooperative Oncology Group worsened. It is suggested that MQOL-J can reflect perceived health status of terminal cancer patients.

Abstract
Transmission ratio distortion (TRD) is frequently observed in inter- and intraspecific hybrids of plants, leading to a violation of Mendelian inheritance. Sex-independent TRD (siTRD) was detected in a hybrid between Asian cultivated rice and its wild ancestor. Here we examined how siTRD caused by an allelic interaction at a specific locus arose in Asian rice species. The siTRD is controlled by the S6 locus via a mechanism in which the S6 allele acts as a gamete eliminator, and both the male and female gametes possessing the opposite allele (S6a) are aborted only in heterozygotes (S6/S6a). Fine mapping revealed that the S6 locus is located near the centromere of chromosome 6. Testcross experiments using near-isogenic lines (NILs) carrying either the S6 or S6a alleles revealed that Asian rice strains frequently harbor an additional allele (S6n) the presence of which, in heterozygotic states (S6/S6n and S6a/S6n), does not result in siTRD. A prominent reduction in the nucleotide diversity of S6 or S6a carriers relative to that of S6n carriers was detected in the chromosomal region. These results suggest that the two incompatible alleles (S6 and S6a) arose independently from S6n and established genetically discontinuous relationships between limited constituents of the Asian rice population.

Abstract
* A sex-independent transmission ratio distortion (siTRD) system detected in the interspecific cross in rice was analyzed in order to understand its significance in reproductive barriers. The S(1) gene, derived from African rice Oryza glaberrima, induced preferential abortion of both male and female gametes possessing its allelic alternative (), from Asian rice O. sativa, only in the heterozygote. * The siTRD was characterized by resolving it into mTRD and fTRD occurring through male and female gametes, respectively, cytological analysis of gametophyte development, and mapping of the S(1) locus using near-isogenic lines. The allelic distribution of the S(1) locus in Asian and African rice species complexes was also analyzed. * The siTRD system involved at least two components affecting male and female gametogeneses, respectively, including a modifier(s) that enhances fTRD. The chromosomal location of the major component causing the mTRD was delimited within an approx. 40 kb region. The S(1) locus induced hybrid sterility in any pairwise combination between Asian and African rice species complexes. * The allelic state of the S(1) locus has diverged between Asian and African rice species complexes, suggesting that the TRD system has a significant role in the reproductive barriers in rice.

Abstract
We have developed an ultrahigh vacuum scanning tunneling microscope with an in situ external stress application capability in order to determine the effects of stress and strain on surface atomistic structures. It is necessary to understand these effects because controlling them will be a key technology that will very likely be used in future nanometer-scale fabrication processes. We used our microscope to demonstrate atomic resolution imaging under external tensile stress and strain on the surfaces of wafers of Si(111) and Si(001). We also successfully observed domain redistribution induced by applying uniaxial stress at an elevated temperature on the surface of a wafer of vicinal Si(100). We confirmed that domains for which an applied tensile stress is directed along the dimer bond become less stable and shrink. This suggests that it may be feasible to fabricate single domain surfaces in a process that controls surface stress and strain.

Abstract
The three quantitative trait loci (qSH1, qSH3, and qSH4) causing reduction of seed shattering were investigated to examine their relative importance during rice domestication. The qSH1 and qSH4 loci showed a distinct effect on the reduction of shattering, compared with the qSH3 locus. Fine mapping and sequence analysis strongly suggested that the qSH1 and qSH4 loci are the same as the recently reported genes. A non-shattering allele at qSH1 drastically changed the shattering phenotype to a non-shattering phenotype even in the presence of shattering alleles at the qSH3 and qSH4 loci, showing that qSH1 is genetically epistatic to the other loci. The level of the reduction in sequence diversity was compared between the qSH1 and qSH4 regions. The sequence diversity was severely reduced in the qSH1 region of Oryza sativa subsp. japonica compared with that of O. sativa subsp. indica, despite that the level of diversity was similarly reduced at the qSH4 region in the 2 subspecies. Phylogenetic reconstruction based on the combined sequences of the flanking sites showed different patterns in the 2 subspecies. The 2 subspecies formed a single clade with respect to qSH4, whereas they were separated into different lineages with respect to qSH1, suggesting that these loci had different histories during rice domestication.

Abstract
* A sex-independent transmission ratio distortion (siTRD) system detected in the interspecific cross in rice was analyzed in order to understand its significance in reproductive barriers. The S(1) gene, derived from African rice Oryza glaberrima, induced preferential abortion of both male and female gametes possessing its allelic alternative (), from Asian rice O. sativa, only in the heterozygote. * The siTRD was characterized by resolving it into mTRD and fTRD occurring through male and female gametes, respectively, cytological analysis of gametophyte development, and mapping of the S(1) locus using near-isogenic lines. The allelic distribution of the S(1) locus in Asian and African rice species complexes was also analyzed. * The siTRD system involved at least two components affecting male and female gametogeneses, respectively, including a modifier(s) that enhances fTRD. The chromosomal location of the major component causing the mTRD was delimited within an approx. 40 kb region. The S(1) locus induced hybrid sterility in any pairwise combination between Asian and African rice species complexes. * The allelic state of the S(1) locus has diverged between Asian and African rice species complexes, suggesting that the TRD system has a significant role in the reproductive barriers in rice.

Abstract
During the "Green Revolution" of rice, high-yielding varieties (HYVs) were developed using a semi-dwarf gene (sd1 or OsGA20ox2). The presence or absence of the two mutant alleles (DGWG type in Dee-geo-woo-gen and JKK type in Jikkoku) were surveyed by PCR using 256 accessions of eight wild and two cultivate rice species. The DGWG allele was detected in a landrace (Oryza sativa) and two accessions of wild rice (O. rufipogon), all of which are from China, showing their limited distribution. Genealogical studies of the OsGA20ox2 gene showed that the 62 sequences of O. sativa and O. rufipogon included 20 distinct haplotypes, indicating that the species complex contained OsGA20ox2 genes from two different lineages. The silent site nucleotide diversities (pi and theta(w)) were extremely low in Japonica rice, suggesting a genetic bottleneck. The haplotype network showed that the DGWG and JKK alleles were derived in different lineages. The DGWG carrier (W1944) had unique polymorphisms in the surrounding region of the locus, suggesting that the DGWG allele has been preserved in the wild progenitor, rather than that the DGWG allele has been introgressed from HYVs to W1944. Although a semi-dwarfing plant is a weak competitor under saturated fields, the crossing experiment revealed that the DGWG variant might have been preserved as a hidden variation in the genetic background of wild rice, without expressing a short-stature.
