Abstract An experiment was conducted with three wheat genotypes differing in their sensitivity to moisture and/or temperature stress study the relationship of chloroplast antioxidant system tolerance. Both and increased glutathione reductase peroxidase decreased membrane stab‐iltty, chlorophyll content stability index all genotypes. Under stress. DL 153–2 showed highest stabihty index, content, activity activity. However, under elevated conditions, HD 2285, a lesser extent 153–2, higher...
Recent studies have identified rice (Oryza sativa) as a major dietary source of inorganic arsenic (As) and poses significant human health risk. The predominant model for plant detoxification heavy metals is complexation with phytochelatins (PCs), synthesized non-translationally by PC synthase (PCS) compartmentalized in vacuoles. In this study, order to restrict As the roots mechanism, transgenic approach has been followed through expression phytochelatin synthase, CdPCS1, from Ceratophyllum...
The role of plant antioxidant system in water stress tolerance was studied three contrasting wheat genotypes. Water imposed at different stages after anthesis resulted a general increase lipid peroxidation (LPO) and decrease membrane stability index (MSI), contents chlorophylls (Chl) carotenoids (Car). Antioxidant enzymes like glutathione reductase ascorbate peroxidase significantly increased under stress. Genotype C 306, which had highest activity, also showed lowest LPO MSI, Chl Car...
Abstract Excess Phosphorus (P) in agriculture is causing serious environmental problems like eutrophication of lakes and rivers. Unlike the enormous information available for phosphate starvation response (P 0 ), very few effect excess P i on plants. Characterization Phosphate Response (EP R) essential designing strategies to increase accumulation tolerance. We show a significant modulation root developmental plasticity under increasing supply . An 20 mM ) produces shallow system...
Abstract A large number of plants have been tested and exploited in search a green chemistry approach for the fabrication gold or other precious metal nanomaterials. Despite potential plant based methods, very little is known about underlying biochemical reactions genes involved biotransformation mechanism AuCl 4 into nanoparticles (AuNPs). In this research, we thus focused on studying effect Au growth formation by analyses transcriptome, proteome ionome shift Arabidopsis . exposure favored...
The unique physico-chemical properties of gold nanoparticles (AuNPs) find manifold applications in diagnostics, medicine and catalysis. Chemical synthesis produces reactive AuNPs generates hazardous by-products. Alternatively, plants can be utilized to produce an eco-friendly manner. To better control the biosynthesis AuNPs, we need first understand detailed molecular response induced by AuCl(-) 4 In this study, carried out global transcriptome analysis root tissue Arabidopsis grown for 12-...
Very little is known about molecular events associated with callus differentiation in indica rice. The genes expressed differentially during shoot meristem initiation were identified on genomic arrays applied to efficiently regenerating rice calli. A thidiazuron (TDZ; N-phenyl-N-thiadiazol-1,2,3-5,ylurea)-dependent regeneration protocol was developed for efficient embryogenesis embryogenic calli induced by TDZ 10 days showed transcriptional modulation of a number photosynthesis, hormone...
Heterotrimeric G-proteins constitute the classical signaling paradigm along with their cognate G-protein coupled receptors (GPCRs) and appropriate downstream effectors. complex is composed of highly conserved Gα, Gβ, Gγ subunits. In present study, we have characterized cis-regulatory elements promoter, signature motifs, transcript profile in response to abiotic stresses, sub-cellular localization β subunit RGB1(I) from Indica rice. The promoter sequence has various stress-related suggesting...
The paper deals with morphological and physiological variability of Colletotrichum falcatum Went on different temperature, pH, medium, nitrogen sources, carbon sources also first time reporting the two National Pathotypes from North East Zone Uttar Pradesh, India. Thirty-four isolates were isolated infected samples sugarcane varieties during survey maintained Oat Meal Agar (OMA) slants as well Petri dishes at 30±1 °C. These showed in their optimum radial growth pattern. all was recorded 8,...
Very little is known about the genes responsible for Au uptake, reduction and detoxification in plants, which indeed essential to understand complex trait of AuNP biosynthesis. We designed a targeted experiment elucidate response plant at transcriptional level under exposure, microarray was performed on root tissue treated with AuCl4 (-) absence nutrient media record specific gene expression signature. Here, we describe experimental procedures data analysis detail reproduce results...
