Differential expression of stress-responsive microRNAs and their target genes under PEG6000-induced osmotic stress in wild and mutation-bred tomato genotypes
Water deficit, intensified by global warming and climate change, is a major constraint on crop productivity, making it essential to understand and enhance plant adaptation to limited water availability. MicroRNAs (miRNAs), small non-coding RNAs of ~ 20–22 nucleotides, are key post-transcriptional regulators of gene exp...
