摘要: 【目的】 回顾与总结番茄MicroRNA(miRNA)调控其生长发育及逆境响应的研究现状及进展,为番茄育种的应用提供理论和科学依据。【方法】 查阅国内外相关文献,汇总并对比分析文献数据。【结果】 miRNA是一类广泛存在于植物体内,位于基因组非编码区长约21~25个核苷酸的内源性非编码小分子RNA。其通过定向降解靶基因mRNA和抑制其翻译,对靶基因表达在转录后水平起调控作用。高通量测序的出现有助于植物miRNAs的数量呈指数增长,使得miRNAs相关数据库种类及数据量日渐丰富。番茄诸多生物学过程都受到miRNA的调控,包括植株形态、器官发育、生长发育以及响应干旱、盐、温度和生物胁迫等方面。【结论】 miRNAs在番茄生长发育和胁迫应答等方面起重要作用,围绕miRNAs及其靶基因对番茄的调控机制,定向改变番茄果实品质及生长周期。

Abstract: 【Objective】 This paper reviews and summarizes the research status and progress of the regulation of tomato miRNAs on its growth and development and response to adversity, so as to provide theoretical and scientific basis for the application of tomato breeding.【Methods】 Consult the relevant literature at home and abroad, summarize and compare the literature data.【Result】 MiRNA is a kind of endogenous noncoding microRNA, which widely exists in plants. It is located in the noncoding region of genome and has about 21-25 nucleotides. It regulates target gene expression at the post-transcriptional level by directional degradation of target gene mRNA and inhibition of its translation. The emergence of high-throughput sequencing is conducive to the exponential growth of the number of plant miRNAs, which makes the types and data volume of miRNAs related databases increasingly rich. Recent research results show that many biological processes of tomato are regulated by miRNA, including plant morphology, organ development, growth and development, and response to drought, salt, temperature, and biological stress.【Conclusion】 MiRNAs play a crucial role in tomato growth and development, and stress response. The research should focus on the regulatory mechanism of miRNAs and their target genes on tomato. In the future, it is expected to change the quality and growth cycle of tomato fruits in a targeted manner, and provide new ideas and methods for tomato resistance to adversity.

Key words: microRNAs; tomato; growth and development; adversity stress
