    摘要:

    miR397是植物中保守的miRNA之一,在不同植物中miR397家族大多由1~3个成员组成。通过调控漆酶基因等miR397广泛参与调控植物生长发育和胁迫响应,从而影响植物种子产量、果实品质等重要经济性状。因此,miR397作为分子育种的重要靶标在植物遗传改良中具有很大的应用潜力。本文对miR397在植物中的分布、miR397靶基因的鉴定、miR397调控植物生长发育和胁迫应答的分子机制进行了评述,并提出了仍有待解决的问题,以期为miR397在植物遗传改良中的应用提供参考。

    Abstract:

    miR397 is one of the conserved miRNAs in plants. In different plants, the miR397 family is mostly composed of one to three members. Through regulating the laccase gene and other genes, miR397 is widely involved in regulating plant growth, development, and stress responses, thus affecting important economic traits such as seed yield and fruit quality. Therefore, as a target gene of molecular breeding, miR397 has great application potential in plant genetic improvement. In this article, the distribution of miR397 in plants, the identification of target genes of miR397, and the regulating roles of miR397 in plant growth, development, and stress responses were reviewed, and the problems that remain to be solved are pointed out, which provides a reference for the application of miR397 in plant genetic improvement.
