Abstract MicroRNAs (miRNAs) are short (19–24 nucleotides in length) noncoding RNAs that have a profound effect on gene expression. By completely or almost perfectly base-pairing with their individual target mRNAs they cause mRNA cleavage or repression of translation. As important regulators, miRNAs plays an important role in the regulation of fruit quality. Extensive studies have been reported in fruits, however current studies are mostly focused on the identification of miRNAs and the prediction and validation of target genes. This review summarizes research progress on the role of miRNAs in regulating fruit ripening and senescence and quality characteristics, such as coloration, flavor metabolism, and texture for providing information for future research.

MicroRNAs调控果实品质特性的研究进展
MicroRNAs（miRNAs）是短的（长度为19-24个核苷酸）非编码RNA，对基因表达有深远的影响。通过完全或几乎完全的碱基与它们的单个靶基因配对，它们会导致mRNA断裂或翻译抑制。miRNAs作为重要的调控因子，在果实品质调控中发挥着重要作用。已有大量的研究报道，但目前的研究主要集中在miRNAs的鉴定和靶基因的预测与验证上。本文综述了miRNAs在果实成熟衰老过程中的调控作用以及在色泽、风味代谢、质地等品质特性方面的研究进展，为今后的研究提供参考。
