Abstract
Interspecific hybridization is widespread for sunflowers, both in wild populations and commercial breeding. One of the most common species that can efficiently cross with Helianthus annuus is the Silverleaf sunflower-Helianthus argophyllus. The current study carried out structural and functional organization analyses of mitochondrial DNA in H. argophyllus and the interspecific hybrid, H. annuus (VIR114A line) × H. argophyllus. The complete mitogenome of H. argophyllus counts 300,843 bp, has a similar organization to the mitogenome of cultivated sunflower, and holds SNPs typical for wild sunflowers. RNA editing analysis predicted 484 sites in H. argophyllus mitochondrial CDS. The mitochondrial genome of the H. annuus × H. argophyllus hybrid is identical to the maternal line (VIR114A). We expected that significant rearrangements in the mitochondrial DNA of the hybrid would occur, due to the frequent recombination. However, the hybrid mitogenome lacks rearrangements, presumably due to the preservation of nuclear-cytoplasmic interaction paths.

Abstract
The sunflower (Helianthus annuus), which belongs to the family of Asteraceae, is a crop grown worldwide for consumption by humans and livestock. Interspecific hybridization is widespread for sunflowers both in wild populations and commercial breeding. The current dataset comprises 250 bp and 76 paired-end NGS reads for six interspecific sunflower hybrids (F1). The dataset aimed to expand Helianthus species genomic information and benefit genetic research, and is useful in alloploids’ features investigations and nuclear–organelle interactions studies. Mitochondrial genomes of perennial sunflower hybrids H. annuus × H. strumosus and H. annuus × H. occidentalis were assembled and compared with parental forms.

Abstract
The significant difference in the mtDNA size and structure with simultaneous slow evolving genes makes the mitochondrial genome paradoxical among all three DNA carriers in the plant cell. Such features make mitochondrial genome investigations of particular interest. The genus Helianthus is a diverse taxonomic group, including at least two economically valuable species-common sunflower (H. annuus) and Jerusalem artichoke (H. tuberosus). The successful investigation of the sunflower nuclear genome provided insights into some genomics aspects and significantly intensified sunflower genetic studies. However, the investigations of organelles' genetic information in Helianthus, especially devoted to mitochondrial genomics, are presented by limited studies. Using NGS sequencing, we assembled the complete mitochondrial genomes for H. occidentalis (281,175 bp) and H. tuberosus (281,287 bp) in the current investigation. Besides the master circle chromosome, in the case of H. tuberosus, the 1361 bp circular plasmid was identified. The mitochondrial gene content was found to be identical for both sunflower species, counting 32 protein-coding genes, 3 rRNA, 23 tRNA genes, and 18 ORFs. The comparative analysis between perennial sunflowers revealed common and polymorphic SSR and SNPs. Comparison of perennial sunflowers with H. annuus allowed us to establish similar rearrangements in mitogenomes, which have possibly been inherited from a common ancestor after the divergence of annual and perennial sunflower species. It is notable that H. occidentalis and H. tuberosus mitogenomes are much more similar to H. strumosus than H. grosseserratus.

Abstract
BACKGROUND Sunflower is an important oilseed crop domesticated in North America approximately 4000 years ago. During the last century, oil content in sunflower was under strong selection. Further improvement of oil properties achieved by modulating its fatty acid composition is one of the main directions in modern oilseed crop breeding. RESULTS We searched for the genetic basis of fatty acid content variation by genotyping 601 inbred sunflower lines and assessing their lipid and fatty acid composition. Our genome-wide association analysis based on the genotypes for 15,483 SNPs and the concentrations of 23 fatty acids, including minor fatty acids, revealed significant genetic associations for eleven of them. Identified genomic regions included the loci involved in rare fatty acids variation on chromosomes 3 and 14, explaining up to 34.5% of the total variation of docosanoic acid (22:0) in sunflower oil. CONCLUSIONS This is the first large scale implementation of high-throughput lipidomic profiling to sunflower germplasm characterization. This study contributes to the genetic characterization of Russian sunflower collections, which made a substantial contribution to the development of sunflower as the oilseed crop worldwide, and provides new insights into the genetic control of oil composition that can be implemented in future studies.

Abstract
This study provides insights into the flexibility of the mitochondrial genome in sunflower (Helianthus annuus L.) as well as into the causes of ANN2-type cytoplasmic male sterility (CMS). De novo assembly of the mitochondrial genome of male-sterile HA89(ANN2) sunflower line was performed using high-throughput sequencing technologies. Analysis of CMS ANN2 mitochondrial DNA sequence revealed the following reorganization events: twelve rearrangements, seven insertions, and nine deletions. Comparisons of coding sequences from the male-sterile line with the male-fertile line identified a deletion of orf777 and seven new transcriptionally active open reading frames (ORFs): orf324, orf327, orf345, orf558, orf891, orf933, orf1197. Three of these ORFs represent chimeric genes involving atp6 (orf1197), cox2 (orf558), and nad6 (orf891). In addition, orf558, orf891, orf1197, as well as orf933, encode proteins containing membrane domain(s), making them the most likely candidate genes for CMS development in ANN2. Although the investigated CMS phenotype may be caused by simultaneous action of several candidate genes, we assume that orf1197 plays a major role in developing male sterility in ANN2. Comparative analysis of mitogenome organization in sunflower lines representing different CMS sources also allowed identification of reorganization hot spots in the mitochondrial genome of sunflower.

Abstract
BACKGROUND More than 70 cytoplasmic male sterility (CMS) types have been identified in Helianthus, but only for less than half of them, research of mitochondrial organization has been conducted. Moreover, complete mitochondrion sequences have only been published for two CMS sources - PET1 and PET2. It has been demonstrated that other sunflower CMS sources like MAX1, significantly differ from the PET1 and PET2 types. However, possible molecular causes for the CMS induction by MAX1 have not yet been proposed. In the present study, we have investigated structural changes in the mitochondrial genome of HA89 (MAX1) CMS sunflower line in comparison to the fertile mitochondrial genome. RESULTS Eight significant major reorganization events have been determined in HA89 (MAX1) mtDNA: one 110 kb inverted region, four deletions of 439 bp, 978 bp, 3183 bp and 14,296 bp, respectively, and three insertions of 1999 bp, 5272 bp and 6583 bp. The rearrangements have led to functional changes in the mitochondrial genome of HA89 (MAX1) resulting in the complete elimination of orf777 and the appearance of new ORFs - orf306, orf480, orf645 and orf1287. Aligning the mtDNA of the CMS sources PET1 and PET2 with MAX1 we found some common reorganization features in their mitochondrial genome sequences. CONCLUSION The new open reading frame orf1287, representing a chimeric atp6 gene, may play a key role in MAX1 CMS phenotype formation in sunflower, while the contribution of other mitochondrial reorganizations seems to appear negligible for the CMS development.

Abstract
Background Cytoplasmic male sterility (CMS) is a common phenotype in higher plants, that is often associated with rearrangements in mitochondrial DNA (mtDNA), and is widely used to produce hybrid seeds in a variety of valuable crop species. Investigation of the CMS phenomenon promotes understanding of fundamental issues of nuclear-cytoplasmic interactions in the ontogeny of higher plants. In the present study, we analyzed the structural changes in mitochondrial genomes of three alloplasmic lines of sunflower (Helianthus annuus L.). The investigation was focused on CMS line PET2, as there are very few reports about its mtDNA organization. Methods The NGS sequencing, de novo assembly, and annotation of sunflower mitochondrial genomes were performed. The comparative analysis of mtDNA of HA89 fertile line and two HA89 CMS lines (PET1, PET2) occurred. Results The mtDNA of the HA89 fertile line was almost identical to the HA412 line (NC_023337). The comparative analysis of HA89 fertile and CMS (PET1) analog mitochondrial genomes revealed 11,852 bp inversion, 4,732 bp insertion, 451 bp deletion and 18 variant sites. In the mtDNA of HA89 (PET2) CMS line we determined 27.5 kb and 106.5 kb translocations, 711 bp and 3,780 bp deletions, as well as, 5,050 bp and 15,885 bp insertions. There are also 83 polymorphic sites in the PET2 mitochondrial genome, as compared with the fertile line. Discussion The observed mitochondrial reorganizations in PET1 resulted in only one new open reading frame formation (orfH522), and PET2 mtDNA rearrangements led to the elimination of orf777, duplication of atp6 gene and appearance of four new ORFs with transcription activity specific for the HA89 (PET2) CMS line—orf645, orf2565, orf228 and orf285. Orf228 and orf285 are the atp9 chimeric ORFs, containing transmembrane domains and possibly may impact on mitochondrial membrane potential. So orf228 and orf285 may be the cause for the appearance of the PET2 CMS phenotype, while the contribution of other mtDNA reorganizations in CMS formation is negligible.

Abstract
The polymorphism of microsatellite loci of chloroplast genome in six Helianthus species and 46 lines of cultivated sunflower H. annuus (17 CMS lines and 29 Rf-lines) were studied. The differences between species are confined to four SSR loci. Within cultivated forms of the sunflower H. annuus, the polymorphism is absent. A comparative analysis was performed on sequences of the cpDNA inbred line 3629, line 398941 of the wild sunflower, and the American line HA383 H. annuus. As a result, 52 polymorphic loci represented by 27 SSR and 25 SNP were found; they can be used for genotyping of H. annuus samples, including cultural varieties: twelve polymorphic positions, of which eight are SSR and four are SNP.

Abstract
A complex comparative genetic approach was used for the investigation of the structural and functional diversity of genes for the restoration of sunflower pollen fertility. It includes (i) hybridological analysis; (ii) analysis of polymorphism among EST fragments.homologous to the known Rf genes that contain repeated motives of 35 amino acids (RFL-PPR); (iii) the development of molecular markers. Monogenic segregation in three interline cross combinations and the results of molecular marker analysis confirmed the allelic differences of parental lines in the Mendelian locus for CMS PET1 pollen fertility restoration. Introns were found in two RFL-PPR fragments. Two allelic variants of the QHL12D20 fragment were detected among the sixty lines of the sunflower genetic collection. An intron of QHL12D20 fragment was homologous to an intron of the AHBP-1B gene; the product of this gene-has a similarity with the transcription factor of the bZIP-family of Arabidopsis. A relationship between the QHL12D20 polymorphism and the functional state of the Rfl locus was revealed.

Abstract
The phosphatidylinositol-4-phosphate-5-kinase type IIa (PIP5K2A) gene has been proposed as a putative susceptibility gene for schizophrenia on both positional and functional grounds. The association between the (N251S)-PIP5K2A (rs10828317) variant and schizophrenia was found in German and Dutch populations but was not replicated in several other populations. The purpose of the study was to examine whether the previously implicated (N251S)-PIP5K2A variant influences susceptibility to schizophrenia in the Russian population of Siberia. Authors studied 355 patients with schizophrenic disorders from the Russian population of Siberia. The control group consisted of 100 healthy. Results confirm the association of the (N251S)-PIP5K2A (rs10828317) polymorphism with schizophrenia (p=0.04, OR=2.48, 95%CI=1.19--5.17 for the CC genotype). The association can be explained by the inability of mutant kinase to activate the phosphatidylinositol-4,5-biphosphate dependent proteins, including neuronal KCNQ channels and glutamate EAAT3 transporters, which leads to the lack of dopaminergic and glutamatergic control in schizophrenic patients carriers of this mutation.

Abstract
The expression of genomic instability was studied at the phenotypical (morphological characters, electrophoretic spectra of seed storage proteins) and molecular (DNA amplification products) levels in interspecific hybrids (ISHs) from crosses of inbred lines of cultivated sunflower Helianthus annuus with perennial species of the genus Helianthus and in introgressive lines (ILs) produced on their basis. Unstable state of the locus determining the trait of lower branching was proved by the method of hybridological analysis. It was shown with the use of RAPD markers that the IL genome is characterized by instability even after long-term inbreeding (in generations F8-F12). In progenies of different combinations of interspecific crosses, identical polymorphous variants-were revealed for a seed storage protein, helianthinin, and for DNA fragments homologous to structural genes of functionally important proteins, suggesting the nonrandom character of ISH genome variation. This variation may be determined by genome reorganizations under the action of a genome shock induced by interspecific hybridization. The factors inducing reorganizations in the genome include the activity of mobile genetic elements (MGEs). Using primers specific to different MGE families, nucleotide sequences with a high level of homology to the sequences of fragments of the mobile elements MuDR, Far1, CACTA, Stowaway, and Tourist were identified in the sunflower genome. The possibility of using MGE fragments for sunflower genotyping was demonstrated.

Abstract
The data on polymorphism and inheritance of the seed storage protein helianthinin are presented. The results of hybrid analysis indicate that in the annual sunflower Helianthus annuus, helianthinin synthesis is controlled by at least three loci: HelA, HelB, HelB, and HelC. Codominant alleles controlling different electrophoretic variants of polypeptides were identified at each of the loci. The HelA locus was inherited independently of HelB and HelC in a series of dihybrid crosses. The frequencies of recombination between loci HelB and HelC estimated in F2 and BC of two crossing combinations were respectively 21.8 and 19.0%. Segregation of the Hel-C-controlled variants in the progenies from the crosses of cultured sunflower with annual wild species and forms corresponded to that theoretically expected for Mendelian inheritance. The maternal type of helianthinin inheritance was observed in the progenies from the crosses of inbred H. annuus lines with perennial diploid and polyploid Helianthus species. Altered expression of the HelC locus was detected in some hybrid combinations. These alterations appeared in early (F1, F2) hybrid generations and were similar in different hybrid combinations. They did not depend on the perennial paternal species being more influenced by the maternal genotype and by the mode of obtaining hybrids (in an embryo culture or in the field). These results are explained by "genomic shock" generated by hybridization of genetically incompatible species.

Abstract
Multiple molecular forms of inhibitors of trypsin (TI) and chymotrypsin (CI), which are typical digestive enzymes of insects, mammals and micro-organisms, and subtilisin (SI), a proteinase of many bacteria and phytopathogenic fungi, were identified in seeds and vegetative organs of the majority of 128 wild and cultivated species representing 65 genera of three of the subfamilies of the Compositae. Inhibitors with M(r) ranging from 7450 to 7800 and combining activities towards subtilisin and trypsin and/or chymotrypsin (T/C/SI) had the widest distribution and may be involved in plant defense mechanisms. They were found in many species of the subfamilies Carduoideae (genera Carthamus, Centaurea, Cirsium), Cichorioideae (Lactuca, Taraxacum) and Asteroideae (Helianthus, Cosmos, Bidens). Partial amino acid sequencing showed that the safflower (Carthamus tinctorius) T/C/SI and Cosmos bipinnatus T/C/SI, T/SI and C/SI belonged to the potato I inhibitor family. The most active, variable and heterogeneous inhibitors were found in species of the tribe Heliantheae, which is placed in the evolutionary advanced subfamily Asteroideae. Seeds of Helianthus species, Eclipta prostrata, Gailardia aristata, Zinnia elegans and Silphium perfoliatum contained various TI with M(r) ranging from 1500 to 14,750, with some also containing SI. H. annuus seeds contain a unique cyclic TI of M(r) 1514 and similar TI were also present in other Helianthus spp. and the related species Tithonia diversifolia. Zinnia elegans contained a TI with M(r) 11,350 which appeared to represent a novel type of inhibitor distantly related to the cereal subgroup of Bowman-Birk inhibitors. TI and T/SI varied widely in H. annuus lines and wild Helianthus species in their presence or absence and composition. Similar T/SI components were found in the cultivated diploid H. annuus and annual diploid species with the B genome but not in perennials with the A genome. Some T/SI, SI and TI were detected in vegetative organs of sunflower and other Compositae. Studies of the polymorphism and distribution of proteinase inhibitors are relevant to the evolution of protective protein systems and the mechanisms of resistance to pathogenic organisms in the Compositae and other plants.

Abstract
It has been shown that when illuminating chlorophyll a solution (approximately 10(-5) M) in ethanol containing small concentrations of hydroquinone at pH higher than 7, a markable negative photopotential (-PhP) is initiated. Similar picture is also observed both in the presence of 2 . 10(-5) M parabenzoquinone and when using pheophytin a instead of chlorophyll. The data obtained are in favour of the idea that when illuminating the solutions of these pigments in ethanol containing pure p-benzoquinone at pH higher than the definite value, PhP initiation is conditioned by photochemical reaction of pigments with equilibrium amounts of hydroquinones or semiquinone always present in quinone solutions.

Abstract
The experience with the treatment of 312 acute blood vessels trauma consecutive cases is generalized in this article. The problems dealing with differential estimation of reconstructive surgery, indications for reconstructive operations on patients with traumatic shock, blood loss and severe ischemia of the injured extremity are considered. Experimental studies on 35 dogs and clinical observations over 95 (30.4%) cases of traumatic shock and blood vessels injury permitted to reveal some peculiarities of homeostasis alterations when the ischemized extremity gets involved into the blood flow, and to show the grounds for using the differential tactics under such conditions.

Abstract
Spectrophotometric study was carried out of the effect of medium polarity on the parabenzoquinone photooxidation of chlorophyll "a" at lower temperature using as solvents toluene and CCl4 containing different quantities of polaric solvents, methanole, ethanole, amilic alkohol, acetone. It is shown that the photoreaction with the formation of primary photooxidized form of the pigment starts only if some amount of the polar component is in the medium. The data are in favour of the suggestion that chlorophyll and quinone in non-polar medium form an reaction complex which disintegrates under the given conditions at a definite value of medium polarity.

Abstract
Under the illumination of ethanol solutions of chlorophyll "alpha" and "beta" in the presence of duroquinone positive photopotential (PP) appears, the sign of which is not changed with an increase of pH. However, if duroquinone is used, which had been illuminated with white light in the absence of air, in ethanol, which results in an increase of concentration of its reduced forms, at neutral weakly alkaline pH the PP sign gets negative. This fact supports the assumption that the change of PP sign at the change of pH when parabenzoquinone is used as an oxidizer results from the change of the direction of electron transfer during photoreaction. During photoreaction of pheophytin incapable of photooxidation with duroquinone and disposed to photoreduction, PP at all pH is negative.
