The mechanisms of perception of arsenic (As)-induced stress and ensuing tolerance in plants remain unresolved. To obtain an insight into these mechanisms, biochemical and transcriptional profiling of two contrasting genotypes of Brassica juncea was performed. After screening 14 varieties for As tolerance, one tolerant (TPM-1) and one sensitive (TM-4)(More)
MicroRNAs (miRNAs) constitute a novel mechanism of gene regulation affecting plant development, growth, and stress response. To study the role of miRNAs in arsenic (As) stress, microarray profiling of miRNAs was performed in Brassica juncea using a custom Phalanx Plant OneArray containing 381 unique miRNA probes representing 618 miRNAs from 22 plant(More)
Coat protein (CP)-mediated resistance against an Indian isolate of the Cucumber mosaic virus (CMV) subgroup IB was demonstrated in transgenic lines of Nicotiana benthamiana through Agrobacterium tumefaciens-mediated transformation. Out of the fourteen independently transformed lines developed, two lines were tested for resistance against CMV by challenge(More)
The present study was aimed to evaluate the effect of different seed priming methods to enhance the sodium chloride (NaCl) and polyethylene glycol-8000 (PEG-8000) stress tolerance in Indian mustard (Brassica juncea L.). Seeds subjected to different priming treatments such as water (hydro-priming), calcium chloride (CaCl2) (chemo-priming), and abscisic acid(More)
A severe leaf curl disease was observed on ~45% of the grain amaranth (Amaranthus cruentus L.) plants growing in experimental plots of CSIR-NBRI, Lucknow, India, during the year 2011. The causal pathogen was transmitted through whiteflies (Bemisia tabaci) from infected to healthy A. cruentus seedlings. Association of Papaya leaf curl virus (PLCV) with the(More)
With the advent of deep sub-microntechnologies,interconnectloads and delays are becoming dominant. Consequently, the currently used design ow of iterativelyperforming logic synthesis with statistical wire-load models, doing placement & routing, extracting par-asitics, and using them back in the synthesis tool runs into serious timing convergence problems.(More)
In the present agricultural scenario, the major thrust is to increase crop productivity so as to ensure sustainability. In an earlier study, foliar application of thiourea (TU; a non physiological thiol based ROS scavenger) has been demonstrated to enhance the stress tolerance and yield of different crops under field condition. Towards this endeavor,(More)
Twenty nine strains of vegetable amaranth (Amaranthus tricolor were grown for two successive seasons to study different selection parameters for foliage yield and its nine contributing morphological and quality traits. The strains AV-38 (5.06 kg/plot) and AV-31 (5.04 kg/plot) recorded highest foliage yield, followed by AV-30 (4.78 kg/plot) and AV-23 (4.70(More)
In cynobacteria and higher plants, salinity is known to inhibit the activity of several enzymes involved in photosynthesis and hence decreases the overall photosynthetic rate. This gave us an impetus to search for a protease, which may be involved in the turnover of non-functional enzymes produced under salinity stress. Taking the possible changes in pH(More)
Past observational and toxicity studies have established an association between the deaths of children and consumption of Cassia occidentalis (CO) seeds. We recently reported chemical evidence of this association following the identification of toxic anthraquinones (AQs), viz. aloe-emodin, chrysophanol, emodin, physcion, and rhein, in CO seeds (Panigrahi,(More)
