摘要:

microRNA(miRNA)是一类非编码小RNA,通过剪切mRNA或抑制翻译调控与其互补的靶基因。近年来,已发现miRNA及其靶基因组成的调控模块广泛且深度地参与植物的生理生化过程。植物miR169及主要靶基因Nuclear Factor Y-As(NFYAs)家族会通过脱落酸介导的激素信号通路参与植物抵御非生物胁迫过程。本文阐述了miR169/NFYA模块在植物非生物胁迫及生长发育中的作用机制,为抗性分子育种提供参考。

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.
