摘要： MicroRNAs (miRNAs) are endogenous noncoding small RNAs containing 21-24 nucleotides (nt) that regulate gene expression precisely and efficiently at the posttranscriptional level through the negative regulation of target messenger RNA (mRNA) expression, such as translational inhibition or degradation. Likewise, as a controlling element, miRNA itself is regulated by a variety of factors when performing its basic purposes, such as SNP detection, miRNA purging, methylation, and the circadian clock in model crops. In current years, miRNA-mediated controls have been intensely investigated in horticultural plants, leading to the discovery of numerous novel mechanisms that exhibit significantly greater mechanistic complexity and distinctive regulatory properties than those explored in model species. In fruit crops, miRNAs play a crucial role corresponding to various biological, metabolic functions and environmental challenges, including growth, expansion, response to biotic and abiotic stress, signaling of growth hormones, and the regulation of secondary product metabolism. In this study, we appraisal the current improvement of small regulatory RNA research in fruit crops, emphasizing miRNA mechanisms and their correlation with key trait rule. Considering that miRNAs engaged in the regulation of all aspects of fruit tree life activities, we focus here on their biosynthesis, target genes, function and regulatory network, as well as the mechanistic connection among them, to provide a theoretic base and breakthrough for upcoming exploration on miRNAs in fruit plants.
