Abstract:
Stress conditions including biotic and abiotic stress influence the normal growth of plant and cause great loss to cropyield. In the long course of evolution,plants have developed intr icate mechanism to resist stressed conditions.Responsive induced expression genes are the representative examples.Under various stressed conditions,not only the protein-coding genes, the non-protein-coding genes will be induced expression also.More and more researches show that the transcripts of these non-protein-coding genes play a big role in regulation of gene expression miRNAs are one of the group of these no-coding regulatory small RNAs. Recent research findings show that in order to resist the biotic and abiotic stresses, miRNA (microRNA) gene will be induced expression and the transcripts (miRNAs) can regulate gene expression by guiding target mRNA cleavage or translational inhibition.This paper focuses on the advances of plant miRNAs research in some stressed conditions,especially the induced expression of miRNA and target genes regulation and its role on the adaptation to stressed conditions.
