Abstract excerpt

Arabidopsis thaliana (Arabidopsis) double-stranded RNA binding (DRB) proteins DRB1, DRB2 and DRB4 perform essential roles in microRNA (miRNA) production, with many of the produced miRNAs mediating aspects of the molecular response of Arabidopsis to abiotic stress. Exposure of the drb1, drb2 and drb4 mutants to mannitol stress showed drb2 to be the most sensitive to this form of osmotic stress. Profiling of the...
