摘要: microRNA(miRNA)是真核生物中广泛存在的一类长21~23个核苷酸的非编码RNA分子,通过与靶基因mRNA的特异结合调节基因转录后表达,在调控细胞周期、生物体发育时序等方面起重要作用。miR160、miR167和miR390 3个miRNAs家族均为靶向ARF(Auxin Response Factor)基因家族,预示着它们在行使调控功能的过程中既有相似性又有特异性。笔者详细阐述了miR160/miR167/miR390在植物发育过程中的调控作用及与其靶基因之间的相互调控关系,发现miR160/miR167/miR390均在植物生长发育过程中发挥重要的作用,但miR160则侧重于调控胚胎和根的发育,miR167侧重于调控植物花和果实的发育,而miR390则对植物横向器官的发育具有调控作用,并且,miR160/miR167/miR390与其靶基因之间存在反馈调节作用。

Abstract: MicroRNA(miRNA)is endogenous and non-coding small RNA with 21-23 nucleotides, and it widely exits in eukaryotes. MiRNAs repress gene expression at post transcriptional level by acting on near-perfect complementary sequences in mRNA coding region to guide cleavage and translational repression, and it plays an important role in regulating cell cycle and development timing of biology. Three miRNA families including miR160, miR167 and miR390 all targeting to ARF(Auxin response factor)gene family have been reviewed, and which indicates that they fulfil the similar and differential function. For example, miR160/miR167/miR390 plays an important role in plant development. But miR160 focuses on regulating embryo and root development, miR167 focuses on the regulation of flowers and fruit development, and miR390 has remarkable effect on regulating plant lateral organ development. Moreover, feedback regulation exists between miR160/miR167/miR390 and their target genes.
