Abstract Background Widespread use of chromium (Cr) contaminated fields due to careless and inappropriate management practices effluent discharge, mostly from industries related metallurgy, electroplating, production paints pigments, tanning, wood preservation elevates its concentration in surface soil eventually into rice plants grains. In spite many previous studies having been conducted on the effects stress, precise molecular mechanisms both phytotoxicity, defense reactions against...
Arsenic (As) contamination in rice leads to yield decline and causes carcinogenic risk human health. Although the role of nitric oxide (NO) reducing As toxicity is known, NO-mediated genetic modulation plant during arsenic has not yet been established. We analyzed key components NO metabolism correlations between interaction stress using as a relevant model plant. Illumina sequencing was used investigate genome-wide temporal transcriptomic root upon AsIII exposure 12 days (d) growth period....
Abstract Arsenic (As) contamination of water is a global concern and rice consumption the biggest dietary exposure to human posing carcinogenic risks, predominantly in Asia. Sulfur (S) involved di-sulfide linkage many proteins plays crucial role As detoxification. Present study explores variable S supply on leaf proteome, its inclination towards amino acids (AA) profile non protein thiols under arsenite exposure. Analysis 282 detected 2-DE gel revealed 113 differentially expressed proteins,...
Drought stress, an inevitable factor due to global climate change, hampers plant biomass production and overall yield. mediated stress sensitivity exerts multi-dimensional effect on transcriptional proteomic variations leading changes in morphological, physiological, metabolic hormonal responses. To cope up water scarcity, plants adapt several drought avoidances or tolerance mechanisms including biochemical, physiological gene regulatory networks, their effective survival. Genomic...
Drought is the major abiotic factors that limit crop productivity worldwide. To withstand stress conditions, plants alter numerous mechanisms for adaption and tolerance. Therefore, in present study, 106 rice varieties were screened drought tolerance phenotype via exposing different concentrations of polyethylene glycol 6000 (PEG) hydroponic nutrient medium at time interval 1, 3, 7 days to evaluate changes their root system architecture. Further, based on obtained after PEG-induced drought,...
A field experiment was conducted during the rabi season of 2012-13 at Research cum Instructional Farm Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) to study effects seaweed saps on growth, yield, nutrient uptake and economic maize (sweet corn) in Matasi soil Chhattisgarh. The foliar spray two different species (namely Kappaphycus Gracilaria) applied thrice interval crop with concentrations (0, 2.5, 5.0, 7.5, 10.0 15% v/v) extracts. Foliar applications extract significantly...
Cadmium (Cd) contamination of aquatic systems is major concern since it a nonessential element and hampers plant growth upon accumulation. The aim this study was to investigate the Cd accumulation behavior coontail plant, Ceratophyllum demersum L., toxicity induced response antioxidant system. Plants were exposed various concentrations (0-10 microM) for period 1-7 days. Accumulation found be concentration duration dependent phenomenon. maximum Cd, 1293 microg g(-1) dw, observed after 7 days...
Chhurpi is a traditional cottage cheese found in different hilly regions of India including Sikkim, Darjeeling, Ladakh, etc. The main aim this study was to explore the preparation process, microbial, and chemical compositions chhurpi Ladakh. There are mainly two types Ladakh: soft hard (sun dried). Results showed that yeast, mold, lactic acid bacteria, Bifidobacterium sp. were major participating microbes Ladakhi chhupri. amount riboflavin (162.71 μg/g), thiamine (64.48 vitamin C (23.53...
Abstract Climatic fluctuations largely affects species turnover and cause major shifts of terrestrial ecosystem. In the present study five decade old herbarium specimens lichens were compared with recent collection from Darjeeling district respect to elements, PAHs accumulation carbon isotope composition (δ 13 C) explore changes in climatic conditions its impact on lichen flora. The δ C has increased which is contrast assumption that anthropogenic emission leads depletion air discrimination...
Traditional leavened wheat based flat bread khambir is a staple food of high altitude people the Western Himalayan region. The health promoting abilities two types khambir, yeast added (YAK) and buttermilk (BAK) were evaluated. A group microbes like yeast, mold, lactic acid bacteria, Bifidobacterium sp. abundant in both but varied proportion. Both are enriched with phenolics flavonoids. aqueous extracts strongly inhibited growth enteropathogens. Molecular docking experiments showed that...
The adverse effects of arsenic (As) contamination are well known. Rice is a staple food for 50% the world population but accumulation As into rice hampers security and safety. Thus amelioration stress reduction levels in needed. In this study, transcriptome (Illumina sequencing) proteome (2D gel electrophoresis) explored mechanisms consortium ( P. putida+C. vulgaris ) mediated growth promotion rice. seedlings grown hydroponically Hewitt nutrient medium after acclimatization, exposed to 50 µM...
In this study, rice plants were co-exposed to selenium (Se) and silica (Si) under arsenic (As) stress evaluate As accumulation in grains, associated cancer risk, its impact on the types numbers of grain metabolites. A total 58 metabolites identified, which, 19 belong sugars, drastically altered during different treatments. Arsenic exposure significantly reduced monosaccharides,
