Cover Story: Plant microRNAs are key regulators of gene expression in development, defense against invading pathogens, and in mounting an adaptive response to environmental stress. Here we report on the use of a high throughput sequencing approach to identify large microRNA cohorts in Arabidopsis thaliana, responsive to the abiotic stresses of heat, drought and salt. The altered abundance of a select number of microRNAs was experimentally validated for each assessed stress, and it was further found that altered microRNA abundance directed opposing changes in the expression of the target gene of each experimentally-validated microRNA. Taken together, this study identifies the Arabidopsis thaliana microRNA/microRNA target gene expression modules responsive to heat, drought and salt stress. View this paper
