摘要: MicroRNAs(miRNAs)是真核生物中普遍存在的一类参与基因表达调控的小分子RNA。miR169家族是植物中保守且规模较大的一类miRNA基因家族,其在转录后水平调控植物中一类保守的转录因子NF-YA(Nuclear transcription factor Y subunit A)。已有研究表明,miR169/NF-YA调控模块对植物的发育和逆境响应起着重要作用。本文对植物miR169基因家族的起源、进化、分子多样性及miR169/NF-YA模块在植物中调控功能的研究进展进行了阐述,特别介绍了miR169/NF-YA参与调控“逆境诱导早花”的分子机制,并展望了未来的研究方向。

Abstract: Plant microRNAs (miRNAs) are a class of small non-coding RNAs which target and regulate the expression of genes involved in several growth, development, and metabolism processes. The miR169 family is the largest and most conserved miRNA family in plants. Recent researches have shown involvement of miR169 members in the regulation of plant responding to abiotic stress and development. Computational prediction and experimental analyses suggest that miR169 targets members of the transcription factor NF-YA gene family. In this review, we summarize the origins, evolution and diversity of miR169 family members. In addition, a comprehensive understanding the regulatory functions of the miR169/NF-YA module in plant with particular emphasis on stress-induced flowering is discussed.
