MicroRNAs (miRNAs) are ubiquitous components of endogenous plant transcriptome. miRNAs are small, single-stranded and ~21 nt long RNAs which regulate gene expression at the post-transcriptional level and are known to play essential roles in various aspects of plant development and growth. Previously, a number of miRNAs have been identified in potato through(More)
Brassica juncea var. Varuna is an economically important oilseed crop of family Brassicaceae which is vulnerable to abiotic stresses at specific stages in its life cycle. Till date no attempts have been made to elucidate genome-wide changes in its transcriptome against high temperature or drought stress. To gain global insights into genes, transcription(More)
Micro RNAs (miRNAs) are involved in diverse biological processes including adaptive response towards abiotic stresses. To unravel small RNAs and more specifically miRNAs that can potentially regulate determinants of abiotic stress tolerance, next generation sequencing of B. juncea seedlings subjected to high temperature, high salt and drought conditions was(More)
Low temperature is a major abiotic stress that impedes plant growth and development. Brassica juncea is an economically important oil seed crop and is sensitive to freezing stress during pod filling subsequently leading to abortion of seeds. To understand the cold stress mediated global perturbations in gene expression, whole transcriptome of B. juncea(More)
Carthamus tinctorius L. (safflower) is an important oilseed crop that is cultivated in several countries. The present study investigates the genetic diversity and population structure of 531 safflower accessions from 43 countries representing all safflower growing regions of the world. Diversity analysis was performed using ten informative EcoRI/MseI(More)
Plants are continuously exposed to a wide range of pathogens, including parasitic nematodes. Being sessile, plant have developed elaborate defense mechanisms that allow them to recognize potential invading pathogens and to initiate successful defenses. Plant parasitic nematodes are ubiquitous, tiny and microscopic animals, which can attack nearly all parts(More)
