Abstract:

microRNA(miRNA)is a small non-coding RNA that negatively regulates its complementary target genes by cleaving mRNA or inhibiting translation. In recent years,the regulatory module of miRNA/target genes is extensively and deeply involved in the plant physiological and biochemical processes. Plant miR169 and the main targets Nuclear Factor Y-As(NFYAs)are also participated in these processes through abscisic acid-mediated hormone signaling pathways. This paper summarizes the mechanism of miR169/NFYA module and their growth and development in plant abiotic stress and provides a reference for in-depth theoretical studies and resistance molecular breeding.

Key words: miR169, NFYA, abiotic stress, plant
