A pathogenic vancomycin-resistant Staphylococcus aureus (VRSA) isolate (MIC > or =64 microg ml(-1)) was obtained from a Kolkata hospital in June 2005. Species identification confirmed by Gram staining, standard biochemical tests and PCR amplification of the nuc gene, which encodes thermostable nuclease that is highly specific for S. aureus. The VRSA also resistant to beta-lactams (amoxicillin, ampicillin, cefepime, cefotaxime, cefuroxime, cephalexin meticillin), chloramphenicol,...
NAC [no apical meristem (NAM), Arabidopsisthaliana transcription activation factor [ATAF1/2] and cup-shaped cotyledon (CUC2)] proteins belong to one of the largest plant-specific (TF) families play important roles in plant development processes, response biotic abiotic cues hormone signalling. Our genome-wide analysis identified 110 StNAC genes potato encoding for 136 proteins, including 14 membrane-bound TFs. The physical map positions on 12 chromosomes were non-random, 40 found be...
Abiotic stresses such as salinity, drought and extreme temperatures affect nitrogen (N) uptake assimilation in plants. However, little is known about the regulation of N pathway genes at transcriptional level under abiotic stress conditions Brassica juncea. In present work, encoding nitrate transporters (NRT), ammonium (AMT), reductase (NR), nitrite (NiR), glutamine synthetase (GS), glutamate synthase (GOGAT), dehydrogenase (GDH), asparagines (ASN) were cloned from juncea L. var. Varuna. The...
Crop plants face a multitude of diverse abiotic and biotic stresses in the farmers' fields. Although there now exists considerable knowledge underlying mechanisms response to individual stresses, crosstalk between pathways various remains enigmatic. Here, we investigated if cytotoxic metabolite methylglyoxal (MG), excess which is generated as common consequence many may serve key molecule linking responses stresses. For this, transgenic rice overexpressing entire two-step glyoxalase pathway...
Edaphic factors such as salinity, sodicity, and drought adversely affect crop productivity, either alone or in combination. Despite soil sodicity being reported an increasing problem worldwide, limited efforts have been made to address this issue. In the present study, we aimed generate rice with tolerance conjunction salinity drought. Using a fusion gene from E. coli coding for trehalose-6-phosphate synthase/phosphatase (TPSP) under control of ABA-inducible promoter, generated marker-free,...
Winter dormancy is a well known mechanism adopted by temperate plants, to mitigate the chilling temperature of winters. However, acquisition sufficient during winter ensures normal phenological traits in subsequent growing period. Thus, low appears play crucial roles growth and development plants. Apple, being an important fruit crop, also requires release traits, which are often associated with yield quality fruits. DNA cytosine methylation one epigenetic modifications remarkably affect...
Crocus sativus stigmas form rich source of apocarotenoids like crocin, picrocrocin and saffranal which besides imparting color, flavour aroma to saffron spice also have tremendous pharmacological properties. Inspite their importance, the biosynthetic pathway is not fully elucidated. Moreover, mechanism stigma specific accumulation remains unknown. Therefore, deep transcriptome sequencing rest flower tissue was done identify genes transcriptional regulators involved in biosynthesis these...
Abstract To unravel the molecular mechanism of defense against blister blight (BB) disease caused by an obligate biotrophic fungus, Exobasidium vexans , transcriptome BB interaction with resistance and susceptible tea genotypes was analysed through RNA-seq using Illumina GAIIx at four different stages during ~20-day cycle. Approximately 69 million high quality reads were assembled de novo yielding 37,790 unique transcripts more than 55% being functionally annotated. Differentially expressed,...
Abstract The MADS-box transcription factors play essential roles in various processes of plant growth and development. In the present study, phylogenetic analysis 142 apple proteins with that other dicotyledonous species identified six putative Dormancy-Associated (DAM) four Flowering Locus C-like (FLC-like) proteins. order to study expression genes, RNA-seq 3 apical 5 spur bud stages during dormancy, 6 flower 7 fruit development was performed. dramatic reduction two MdDAMs , MdMADS063...
Summary Polyphosphate kinase 1 (PPK1) helps bacteria to survive under stress. The ppk1 gene of Mycobacterium tuberculosis was overexpressed in Escherichia coli and characterized. Residues R230 F176, predicted be present the head domain PPK1, were identified as residues critical for polyphosphate (polyP)‐synthesizing ability dimerization PPK1. A knockout mutant smegmatis compromised its long‐term hypoxia. transcription rel synthesis stringent response regulator ppGpp impaired restored after...
Abstract Background Drought tolerance is an attribute maintained in plants by cross-talk between multiple and cascading metabolic pathways. Without a sequenced genome available for horse gram, it difficult to comprehend such complex networks intercalated genes associated with drought of gram ( Macrotyloma uniflorum ). Therefore, de novo transcriptome discovery analyses was done this highly tolerant yet under exploited legume decipher its genetic makeup. Results Eight samples comprising shoot...
Abstract Stevia is a natural source of commercially important steviol glycosides (SGs), which share biosynthesis route with gibberellic acids (GAs) through plastidal MEP and cytosolic MVA pathways. Ontogeny-dependent deviation in SGs one the key factor for global cultivation Stevia, has not been studied at transcriptional level. To dissect underlying molecular mechanism, we followed transcriptome sequencing approach generated more than 100 million reads. Annotation 41,262 de novo assembled...
Abstract Aluminum (Al) toxicity is a major limiting factor for plant growth and productivity in acidic soil. At pH lower than 5.0 (pH < 5.0), the soluble toxic form of Al (Al 3+ ions) enters root cells inhibits uptake water nutrients. The organic acids malate, citrate, oxalate are secreted by roots chelate to non‐toxic Al‐OA complex, which decreases entry into cells. When enters, it leads production reactive oxygen species (ROS) cells, cause damage biomolecules like lipids, carbohydrates,...
