Abstract
Centrins are cytoskeletal proteins associated with the centrosomes or basal bodies in the eukaryotes. We previously reported the involvement of Centrin 1-3 proteins in cell division in the protozoan parasites Leishmania donovani and Trypanosoma brucei. Centrin4 and 5, unique to such parasites, had never been characterized in Leishmania parasite. In the current study, we addressed the function of centrin4 (LdCen4) in Leishmania. By dominant-negative study, the episomal expression of C-terminal truncated LdCen4 in the parasite reduced the parasite growth. LdCen4 double allele gene deletion by either homologous recombination or CRISPR-Cas9 was not successful in L. donovani. However, CRISPR-Cas9-based deletion of the homologous gene was possible in L. mexicana, which attenuated the parasite growth in vitro, but not ex vivo in the macrophages. LdCen4 also interacts with endogenous and overexpressed LdPOC protein, a homolog of centrin reacting human POC (protein of centriole) in a calcium sensitive manner. LdCen4 and LdPOC binding has also been confirmed through in silico analysis by protein structural docking and validated by co-immunoprecipitation. By immunofluorescence studies, we found that both the proteins share a common localization at the basal bodies. Thus, for the first time, this article describes novel centrin4 and its binding protein in the protozoan parasites.

Abstract
One of the major obligate plant parasites causing massive economic crop losses belongs to the class of root-knot nematodes (RKNs). Targeting of major nematode parasitism genes via Host Delivered-RNAi (HD-RNAi) to confer silencing is established as one of the most effective approaches to curb nematode infection. Utilizing nematode-responsive root-specific (NRRS) promoters to design a dsRNA molecule targeting approach to hamper nematode parasitism. Here, a previously validated peroxidase gall specific promoter, pAt2g18140, from Arabidopsis was employed to express the dsRNA construct of the nematode effector gene Mi-msp2 from Meloidogyne incognita. Arabidopsis RNAi lines of CaMV35S::Mi-msp2-RNAi and pAt2g18140::Mi-msp2-RNAi were compared with control plants to assess the decrease in plant nematode infection. When subjected to infection, the maximum reductions in the numbers of galls, females and egg masses in the CaMV35S::Mi-msp2-RNAi lines were 61%, 66% and 95%, respectively, whereas for the pAt2g18140::Mi-msp2-RNAi lines, they were 63%, 68% and 100%, respectively. The reduction in transcript level ranged from 79%-82% for CaMV35S::Mi-msp2-RNAi and 72%-79% for the pAt2g18140::Mi-msp2-RNAi lines. Additionally, a reduction in female size and a subsequent reduction in next-generation fecundity demonstrate the efficacy and potential of the gall specific promoter pAt2g18140 for utilization in the development of HD-RNAi constructs against RKN, as an excellent alternative to the CaMV35S promoter.

Abstract
Cereals are a rich source of vitamins, minerals, carbohydrates, fats, oils and protein, making them the world’s most important source of nutrition. The influence of rising global population, as well as the emergence and spread of disease, has the major impact on cereal production. To meet the demand, there is a pressing need to increase cereal production. Optimal seed development is a key agronomical trait that contributes to crop yield. The seed development and maturation is a complex process that includes not only embryo and endosperm development, but also accompanied by huge physiological, biochemical, metabolic, molecular and transcriptional changes. This chapter discusses the growth of cereal seed and highlights the novel biological insights, with a focus on transgenic and new molecular breeding, as well as biotechnological intervention strategies that have improved crop yield in two major cereal crops, primarily wheat and rice, over the last 21 years (2000–2021).

Abstract
The root-knot nematode (RKN) Meloidogyne incognita is considered one of the most damaging pests among phytonematodes. The majority of nematode oesophageal gland effector genes are indispensable in facilitating M. incognita parasitization of host plants. We report the effect of host-delivered RNAi (HD-RNAi) silencing of four selected M. incognita effector genes, namely, Mi-msp3, Mi-msp5, Mi-msp18 and Mi-msp24, in Arabidopsis thaliana. Mi-msp5, Mi-msp18 and Mi-msp24, which are dorsal gland genes, were found to be maximally expressed in the adult female stage, whereas Mi-msp3, which is a sub-ventral gland gene, was maximally expressed in an earlier stage. In transgenic plants expressing dsRNA, the reduction in the number of galls on roots was 89 %, 78 %, 86 % and 89 % for the Mi-msp3, Mi-msp5, Mi-msp18 and Mi-msp24 RNAi events, respectively. Moreover, gene transcript abundance was significantly reduced in RKN females feeding on dsRNA-expressing lines by up to 60 %, 84 %, 31 % and 61 % for Mi-msp3, Mi-msp5, Mi-msp18 and Mi-msp24, respectively. Furthermore, the M. incognita reproduction factor was reduced up to 71-, 344-, 107- and 114-fold in Arabidopsis plants expressing Mi-msp3, Mi-msp5, Mi-msp18 and Mi-msp24 dsRNA constructs, respectively. This study provides a set of potential target genes to curb nematode infestation in economically important crops via the HD-RNAi approach.

Abstract
Leishmania donovani, a protozoan parasite of family Trypanosomatidae, causes fatal visceral leishmaniasis (VL) in the Indian subcontinent and Africa and cutaneous leishmaniasis (CL) in Sri Lanka. Another member of Trypanosomatidae, Leptomonas seymouri, resembling Leishmania was discovered recently to co-exist with L. donovani in the clinical samples from India and Sri Lanka and therefore, interfere with its investigations. We earlier described a method for selective elimination of such co-existing L. seymouri from clinical samples of VL exploiting the differential growth of the parasites at 37 °C in vitro. Here, we explored ways for a rapid discriminatory diagnosis using high resolution melting (HRM) curves to detect co-occurring L. seymouri with L. donovani in clinical samples. Initial attempt with kDNA-minicircle (mitochondrial DNA) based HRM did not display different Tm values between L. donovani and L. seymouri. Surprisingly, all of their minicircle sequences co-existed in similar clades in the dendrogram analysis, although the kDNA sequences are known for its species and strain specific variations among the Trypanosomatids. However, an HRM analysis that targets the HSP70 gene successfully recognized the presence of L. seymouri in the clinical isolates. This discovery will facilitate rapid diagnosis of L. seymouri and further investigations in to this elusive organism, including the clinico-pathological implications of its co-existence with L. donovani in patients.

Abstract
Root-knot nematodes (RKNs) are devastating parasites that infect thousands of plants. As RKN infection is facilitated by oesophageal gland effector genes, one such effector gene, Mi-msp2, was selected for a detailed characterization. Based on domain analysis, the Mi-MSP2 protein contains an ShKT domain, which is likely involved in blocking K+ channels and may help in evading the plant defence response. Expression of the Mi-msp2 gene was higher in juveniles (parasitic stage of RKNs) than in eggs and adults. Stable homozygous transgenic Arabidopsis lines expressing Mi-msp2 dsRNA were generated, and the numbers of galls, females and egg masses were reduced by 52-54%, 60-66% and 84-95%, respectively, in two independent RNAi lines compared with control plants. Furthermore, expression analysis revealed a significant reduction in Mi-msp2 mRNA abundance (up to 88%) in female nematodes feeding on transgenic plants expressing dsRNA, and northern blot analysis confirmed expression of the Mi-msp2 siRNA in the transgenic plants. Interestingly, a significant reduction in the reproduction factor was observed (nearly 40-fold). These data suggest that the Mi-msp2 gene can be used as a potential target for RKN management in crops of economic importance.

Abstract
Abstract
Mungbean [Vigna radiata (L.) R. Wilczek var. radiata] is vital grain legume having nutritional and socio-economic importance, especially in the developing countries. We performed whole genome re-sequencing of three accessions representing the wild progenitor species, released and landrace of mungbean to identify SNPs with relevance to genetic relationships analyses. Approximately 9.3 million raw reads were obtained by using Ion Torrent PGM™ platform and more than 92% of the reads were mapped to the reference mungbean genome. We identified a total of 233,799 single nucleotide polymorphisms in relation to the reference genome (SNPs: 103,341 in wild, 93,078 in released and 37,380 in landrace accessions) and 9,544 insertions and deletions (InDels: 4,742 in wild, 3,608 in released and 1,194 in landrace accessions) in the coding and non-coding regions. In all accessions, genomic variants were unevenly distributed within and across the mungbean chromosomes. Among these 5,339; 4,739 and 1,795 SNPs were non-synonymous in 815, 790 and 317 genes of wild, released and landrace accessions, respectively. These polymorphisms might contribute to the variation in important pathways of genes for abiotic and biotic stress tolerance and important agronomic traits such as seed dormancy, flowering time and seed size in mungbean. Among the randomly selected SNPs, a selected subset was validated using Sanger sequencing technique. The genomic variations among mungbean wild, released and landrace accessions constitute a powerful tool to support genetic research and molecular breeding of mungbean.

Abstract
Circadian clock genes holds tremendous potential for breeding crops better adapted to environmental fluctuations inherent to climate change. Endogenous TOC1 promoter and CCA1 gene from rice were isolated, cloned and mobilized into pCAMBIA1300 vectors and RNAi constructs A, B and C. Embryogenic calli of varying ages derived from mature seeds of Taipei 309 were employed for Agrobacterium-mediated genetic transformation generating T0, T1 and T2 independent transgenic lines were analyzed for over-expression and repression of CCA1 gene along with various morphological traits. Six hundred and thirty two T0 transgenic plants were generated from rice calli using constructs A, B and C. T0 progeny plants derived from constructs A, B and C did not show any considerable difference in morphological traits. T1and T2 progeny plants derived from construct A exhibited over-expression of CCA1 gene, on the contrary, progeny plants derived from RNAi constructs B and C exhibited repression of CCA1 gene in qRT-PCR analysis at different time points and showed rhythmicity peaking at dawn (6:00 AM) and lowest expression at 12:00 Noon. T1 and T2 progeny plants derived from construct A, namely, A-17 and A-45 exhibited reduced number of tillers/panicles (6–8), reduced thousand seed weight (10.1–16.6g), decreased seed length (4.98 to 6.58mm), decreased seed width (1.1–1.8mm) as compared to wild type plants. T1 and T2 progeny plants of construct B and C showed increased number of tillers/panicles (8–19), better seed yield (4.98–28.9g), increased thousand seed weight (15.6–29.03g), slightly increased seed length (5.7–7.43mm) and slightly increased seed width (1.7–2.98mm) as compared to wild type plants. Chlorophyll content in T1 and T2 progeny plants did not show any significant difference among the three constructs, however, rhythmicity was observed over the period of time in conjunction to CCA1 gene expression. Evidence has been presented which demonstrates that endogenous repression of CCA1 gene resulted in improved morphological traits: increased number of tillers/panicle, thousand seed weight, seed size; whereas, over-expression leads to diminution in morphological traits: decreased number of tillers/panicle, thousand seed weight, seed size as compared to the wild type in T1 and T2 progeny plants. This is first report of successful regulation of endogenous CCA1 gene under control of TOC1 promoter and its effect on improved growth vigor in Japonica rice.

Abstract
RNA editing is a process which leads to post-transcriptional alteration of the nucleotide sequence of the corresponding mRNA molecule which may or may not lead to changes at the protein level. Apart from its role in providing variability at the transcript and protein levels, sometimes, such changes may lead to abnormal expression of the mitochondrial gene leading to a cytoplasmic male sterile phenotype. Here we report the editing status of 20 major mitochondrial transcripts in both male sterile (AKCMS11) and male fertile (AKPR303) pigeonpea genotypes. The validation of the predicted editing sites was done by mapping RNA-seq reads onto the amplified mitochondrial genes, and 165 and 159 editing sites were observed in bud tissues of the male sterile and fertile plant respectively. Among the resulting amino acid alterations, the most frequent one was the conversion of hydrophilic amino acids to hydrophobic. The alterations thus detected in our study indicates differential editing, but no major change in terms of the abnormal protein structure was detected. However, the above investigation provides an insight into the behaviour of pigeonpea mitochondrial genome in native and alloplasmic state and could hold clues in identification of editing factors and their role in adaptive evolution in pigeonpea.

Abstract
The present study was conducted to assess the morphophysiological and biochemical responses during different developmental stages in mungbean varieties subjected to drought stress, and to screen the varieties for drought tolerance. A field experiment was performed according to a completely randomized design on 25 mungbean varieties with 3 replicates per variety. Stress treatment was applied at 3 levels: control (no stress), vegetative stage (25 days after sowing), and reproductive stage (35 days after sowing). According to combined analysis of variance, there were significant effects from drought stress on relative water content (RWC), membrane stability index (MSI), protein and proline content of leaves, leaf area, plant height, and yield traits. MSI, RWC, protein content, leaf area, plant height, and yield traits were decreased during drought stress, while proline content was increased under drought stress conditions. The results showed that the vegetative stage was more sensitive to drought stress, which was further supported by correlation analysis. Taken together, Vigna sublobata, MCV-1, PLM-32, LGG-407, LGG-450, TM-96-2, and Sattya varieties were identified as drought tolerant as they maintained the higher values of RWC, MSI, protein, proline content, leaf area, plant height, and yield traits. These varieties could be used in breeding programs for better physiological drought tolerance traits.

Abstract
Background & objectives: Scrub typhus is a vector-borne zoonotic infection caused by Orientia tsutsugamushi. Local epidemiology of the circulating serotypes of scrub typhus is not available from most parts of India. We conducted this study for the diagnosis of scrub typhus using IgM ELISA and to detect O. tsutsugamushi serotypes circulating in southern Andhra Pradesh, India. Methods: Samples were collected from patients clinically suspected to have scrub typhus and were subjected to IgM ELISA to measure IgM antibodies against O. tsutsugamushi. Nested polymerase chain reaction (PCR) was performed targeting strain-specific regions in ELISA-positive samples. Results: Of a total of 663 samples, 258 (38.91%) were found to be positive by IgM ELISA. Serotypes could be detected in 230 (34.69%) samples only. Only two serotypes, Karp and Kawasaki, were found in the serum samples, with the former being predominant. The dual infection of Karp and Kawasaki serotypes was found in seven patients. Other serotypes such as Gilliam, Kuroki and Kato were not detected in the samples. Interpretation & conclusion: The nested PCR products proved useful in presumptively identifying the endemic O. tsutsugamushi serotypes. The present study could be significant in understanding scrub typhus epidemiology in this region.

Abstract
AIMS The present study aimed to investigate the anti-Staphylococcus aureus and anti-biofilm properties of 4-methoxy-1-methyl-2-oxopyridine-3-carbamide (MMOXC) on S. aureus UDP-MurNAc-pentapeptide (MurF), peptidyl deformylase (PDF) and uridine monophosphate kinase (UMPK). METHODS AND RESULTS The in vitro efficacy of MMOXC was evaluated using quantitative polymerase chain reaction, in vitro assays and broth microdilution methods. Further, the minimum inhibitory concentration (MIC), IC50 and zone of inhibition were recorded in addition to the anti-biofilm property. MMOXC inhibited pure recombinant UMPK and PDF enzymes with a Ki of 0·37 and 0·49 μmol l-1 . However Ki was altered for MurF with varying substrates. The MurF Ki for UMT, d-Ala-d-Ala and ATP as substrates was 0·3, 0·25 and 1·4 μmol l-1 , respectively. Real-time PCR analysis showed a significant reduction in PDF and MurF expression which correlated with the MIC90 at 100 μmol l-1 and IC50 in the range 42 ± 1·5 to 50 ± 1 μmol l-1 against all strains tested. At 5 μmol l-1 MMOXC was able completely to remove preformed biofilms of S. aureus and other drug resistant strains. CONCLUSIONS MMOXC was able to kill S. aureus and drug resistant strains tested by inhibiting MurF, UMPK and PDF enzymes and completely obliterated preformed biofilms. SIGNIFICANCE AND IMPACT OF THE STUDY Growth reduction and biofilm removal are prerequisites for controlling S. aureus infections. In this study MMOXC exhibited prominent anti-S. aureus and anti-biofilm properties by blocking cell wall formation, RNA biosynthesis and protein maturation.

Abstract
The indigenous domestic duck (Anas platyrhynchos domestica) which is domesticated from Mallard (Anas platyrhynchos) contributes significantly to poor farming community in coastal and North Eastern regions of India. For conservation and maintenance of indigenous duck populations it is very important to know the existing genetic diversity and population structure. To unravel the population structure and genetic diversity among the five indigenous duck populations of India, the mitochondrial D-loop sequences of 120 ducks were analyzed. The sequence analysis by comparison of mtDNA D-loop region (470 bp) of five Indian duck populations revealed 25 mitochondrial haplotypes. Pairwise FST value among populations was 0.4243 (p < .01) and the range of nucleotide substitution per site (Dxy) between the five Indian duck populations was 0.00034-0.00555, and the net divergence (Da) was 0-0.00355. The phylogenetic analysis in the present study unveiled three clades. The analysis revealed genetic continuity among ducks of coastal region of the country which formed a separate group from the ducks of the inland area. Both coastal as well as the land birds revealed introgression of the out group breed Khaki Campbell, which is used for breed improvement programs in India. The observations revealed very less selection and a single matrilineal lineage of indigenous domestic ducks.

Abstract
Trypanosomosis (Surra) is an economically important disease caused by Trypanosoma evansi which is an extracellular parasite present in the plasma, tissues and other body fluids of a wide range of hosts including domesticated animals. Currently, serological reports are based on detection of antibodies by ELISA using whole cell lysate (WCL) antigen, which has a limitation of persistence of anti-trypanosomal antibodies after successful treatment of the disease. Moreover, it has some ethical issues also like requirement of mice for in vivo maintenance of parasite for preparing the antigen. Therefore, in the present study, an attempt was made to evaluate the in vitro production of recombinant heat shock protein 70 (HSP70) for detection of antibodies in experimentally infected ponies. The amino acid sequence analysis of HSP70 revealed that N-terminal region of the protein was highly conserved while the C-terminal region was most divergent. The four different regions of HSP70 protein viz. HSP-1, HSP-2, HSP-3 and HSP-4 were cloned and expressed, among which HSP-1 (N-terminal region) & HSP-2 (C-terminal region) were truncated while HSP-3 & HSP-4 were complete C-terminal proteins. The recombinant fragments were probed with sequentially pooled experimental serum samples where antibodies were detected in these fragments from 10(th) day post infection till the termination of the experiment. Further, these recombinant fragments were also comparatively evaluated with WCL antigen in ELISA using experimental as well as field serum samples. It was observed that after successful treatment of infected ponies, there was a sharp fall in antibodies (within 90 days) when tested with recombinant HSP's fragments, while antibodies persisted even after 469 days when tested against WCL antigen. The sensitivity and specificity of all HSP70 fragments were also estimated from field serum samples with reference to WCL antigen ELISA. The HSP-1 showed minimum sensitivity (41.03%) among all the recombinant fragments. Among the C-terminal fragments, maximum sensitivity was observed with the HSP-2 (61.54%) while minimum was observed with HSP-4 (48.72%). The specificity increases for recombinant fragments from N-terminal to C-terminal region of protein and maximum specificity was observed with HSP-4 fragment (91.3%).

Abstract
Shikonin possess a diverse spectrum of pharmacological properties in multiple therapeutic areas. However, the nociceptive effect of shikonin is not largely known. To investigate the antinociceptive potential of shikonin, panel of GPCRs, ion channels, and enzymes involved in pain pathogenesis were studied. To evaluate the translation of shikonin efficacy in vivo, it was tested in 3 established rat pain models. Our study reveals that shikonin has significant inhibitory effect on pan sodium channel/N1E115 and NaV1.7 channel with half maximal inhibitory concentration (IC50) value of 7.6 μmol/L and 6.4 μmol/L, respectively, in a cell-based assay. Shikonin exerted significant dose dependent antinociceptive activity at doses of 0.08%, 0.05%, and 0.02% w/v in pinch pain model. In mechanical hyperalgesia model, dose of 10 and 3 mg/kg (intraperitoneal) produced dose-dependent analgesia and showed 67% and 35% reversal of hyperalgesia respectively at 0.5 h. Following oral administration, it showed 39% reversal at 30 mg/kg dose. When tested in first phase of formalin induced pain, shikonin at 10 mg/kg dose inhibited paw flinching by ∼71%. In all studied preclinical models, analgesic effect was similar or better than standard analgesic drugs. The present study unveils the mechanistic role of shikonin on pain modulation, predominantly via sodium channel modulation, suggesting that shikonin could be developed as a potential pain blocker.

Abstract
Pigeonpea (Cajanus cajan (L.) Millspaugh), a diploid (2n = 22) legume crop with a genome size of 852 Mbp, serves as an important source of human dietary protein especially in South East Asian and African regions. In this study, the draft chloroplast genomes of Cajanus cajan and Cajanus scarabaeoides (L.) Thouars were generated. Cajanus scarabaeoides is an important species of the Cajanus gene pool and has also been used for developing promising CMS system by different groups. A male sterile genotype harboring the C. scarabaeoides cytoplasm was used for sequencing the plastid genome. The cp genome of C. cajan is 152,242bp long, having a quadripartite structure with LSC of 83,455 bp and SSC of 17,871 bp separated by IRs of 25,398 bp. Similarly, the cp genome of C. scarabaeoides is 152,201bp long, having a quadripartite structure in which IRs of 25,402 bp length separates 83,423 bp of LSC and 17,854 bp of SSC. The pigeonpea cp genome contains 116 unique genes, including 30 tRNA, 4 rRNA, 78 predicted protein coding genes and 5 pseudogenes. A 50 kb inversion was observed in the LSC region of pigeonpea cp genome, consistent with other legumes. Comparison of cp genome with other legumes revealed the contraction of IR boundaries due to the absence of rps19 gene in the IR region. Chloroplast SSRs were mined and a total of 280 and 292 cpSSRs were identified in C. scarabaeoides and C. cajan respectively. RNA editing was observed at 37 sites in both C. scarabaeoides and C. cajan, with maximum occurrence in the ndh genes. The pigeonpea cp genome sequence would be beneficial in providing informative molecular markers which can be utilized for genetic diversity analysis and aid in understanding the plant systematics studies among major grain legumes.

Abstract
The present immuno-diagnostic method using soluble antigens from whole cell lysate antigen for trypanosomosis have certain inherent problems like lack of standardized and reproducible antigens, as well as ethical issues due to in vivo production, that could be alleviated by in vitro production. In the present study we have identified heat shock protein 70 (HSP70) from T. evansi proteome. The nucleotide sequence of T. evansi HSP70 was 2116 bp, which encodes 690 amino acid residues. The phylogenetic analysis of T. evansi HSP70 showed that T. evansi occurred within Trypanosoma clade and is most closely related to T. brucei brucei and T. brucei gambiense, whereas T. congolense HSP70 laid in separate clade. The two partial HSP70 sequences (HSP-1 from N-terminal region and HSP-2 from C-terminal region) were expressed and evaluated as diagnostic antigens using experimentally infected equine serum samples. Both recombinant proteins detected antibody in immunoblot using serum samples from experimental infected donkeys with T. evansi. Recombinant HSP-2 showed comparable antibody response to Whole cell lysate (WCL) antigen in immunoblot and ELISA. The initial results indicated that HSP70 has potential to detect the T. evansi infection and needs further validation on large set of equine serum samples.

Abstract
BACKGROUND Aberrant activity of epidermal growth factor receptor (EGFR) family proteins has been found to be associated with a number of human cancers including that of lung and breast. Consequently, the search for EGFR family inhibitors, a well established target of pharmacological and therapeutic value has been ongoing. Therefore, over the years several small molecules, which compete for ATP in the kinase domain have been synthesised and some of them have proved to be effective in attenuating EGFR mediated proliferation. Thus, there exists in literature a vast amount of experimental data on EGFR tyrosine kinase inhibitors. In this paper, we describe a comprehensive database EGFRIndb that contains details of the small molecular inhibitors of EGFR family. DESCRIPTION EGFRIndb is a literature curated database of small synthetic molecular inhibitors of EGFR. It consists of 4581 compounds showing in vitro inhibitory activities (IC50, IC80, GI50, GI90, EC50, Ki, Kd and percentage inhibition) either against EGFR or its different isoforms i.e. Erbb2 (v-erb-b2 avian erythroblastic leukaemia viral oncogene homolog 2) and Erbb4 (v-erb-b2 avian erythroblastic leukaemia viral oncogene homolog 4) or various mutants. For each compound, database provides information on structure, experimentally determined inhibitory activity of compound against kinase as well as various cell lines, properties (physical, elemental and topological) and drug likeness. Additionally, it provides information on irreversible as well as dual inhibitors that have gained importance in recent years due to the emergence of clinical resistance to known drugs. As compound activity against similar kinases is a measure of its selectivity and specificity, the database also provides this information. It also provides simple search, advanced search, browse facility as well as a tool for structure based searching. CONCLUSION EGFRIndb gathers biological and chemical information on EGFR inhibitors from the literature. It is hoped that it will serve as a useful resource in drug discovery and provide data for docking, virtual screening and Quantitative structure-activity relationship (QSAR) model development to the cancer researchers.

Abstract
Grafting is a well-established practice to facilitate asexual propagation in horticultural and agricultural crops. It has become a method for studying molecular aspects of root-to-shoot and/or shoot-to-root signaling events. The objective of this study was to investigate differences in gene expression between the organs of the scion and rootstock of a homograft (Arabidopsis thaliana). MapMan and Gene Ontology enrichment analysis revealed differentially expressed genes from numerous functional categories related to stress responses in the developing flower buds and leaves of scion and rootstock. Meta-analysis suggested induction of drought-type responses in flower buds and leaves of the scion. The flower buds of scion showed over-representation of the transcription factor genes, such as Homeobox, NAC, MYB, bHLH, B3, C3HC4, PLATZ etc. The scion leaves exhibited higher accumulation of the regulatory genes for flower development, such as SEPALLATA 1-4, Jumonji C and AHL16. Differential transcription of genes related to ethylene, gibberellic acid and other stimuli was observed between scion and rootstock. The study is useful in understanding the molecular basis of grafting and acclimation of scion on rootstock.

Abstract
Fungal infections are being increasingly reported from immuno-compromised as well as immuno-competent patients. Transplant patients are on long term immunosuppressive therapy which makes them highly vulnerable to opportunistic fungal infections .These infections can be cutaneous or systemic. Several fungi have been reported to be the culprits such as Candida spp., Aspergillus spp., C. neoformans, P. carinii, and zygomycetes group of fungi. Cutaneous infections are most commonly caused by Pityriasis (tinea) versicolor, dermatophytes, and candida sp but these days the demtiaceous fungi are becoming more frequently reported .Here we report a case of post renal transplant cutaneous infection caused by dematiaceous fungus belonging to the order Pleosporales.

Abstract
Guggulsterone is an aromatic steroidal ketonic compound obtained from vertical rein ducts and canals of bark of Commiphora wightii (Arn.) Bhandari (Family - Burseraceae). Owing to its multifarious medicinal and therapeutic values as well as its various other significant bioactivities, guggulsterone has high demand in pharmaceutical, perfumery and incense industries. More and more pharmaceutical and perfumery industries are showing interest in guggulsterone, therefore, there is a need for its quantitative determination in existing natural populations of C. wightii. Identification of elite germplasm having higher guggulsterone content can be multiplied through conventional or biotechnological means. In the present study an effort was made to estimate two isoforms of guggulsterone i.e. E and Z guggulsterone in raw exudates of 75 accessions of C. wightii collected from three states of North-western India viz. Rajasthan (19 districts), Haryana (4 districts) and Gujarat (3 districts). Extracted steroid rich fraction from stem samples was fractionated using reverse-phase preparative High Performance Liquid Chromatography (HPLC) coupled with UV/VIS detector operating at wavelength of 250 nm. HPLC analysis of stem samples of wild as well as cultivated plants showed that the concentration of E and Z isomers as well as total guggulsterone was highest in Rajasthan, as compared to Haryana and Gujarat states. Highest concentration of E guggulsterone (487.45 μg/g) and Z guggulsterone (487.68 μg/g) was found in samples collected from Devikot (Jaisalmer) and Palana (Bikaner) respectively, the two hyper-arid regions of Rajasthan, India. Quantitative assay was presented on the basis of calibration curve obtained from a mixture of standard E and Z guggulsterones with different validatory parameters including linearity, selectivity and specificity, accuracy, auto-injector, flow-rate, recoveries, limit of detection and limit of quantification (as per norms of International conference of Hormonization). Present findings revealed the role of environmental factors on biosynthesis of guggulsterone isomers under natural conditions.
