The microRNAs (miRNAs) comprise a broad class of non-coding small endogenous RNAs that are associated with many biological processes through the regulation of target genes, such as leaf morphogenesis and polarity, biotic and abiotic stress responses, and root and flower development. We identified a miRNA that affects flower development, miR319a, in Prunus mume. The Pm-miR319a target, Pm-TCP4, was validated by 5'RACE. The higher expression of Pm-TCP4 in imperfect flowers showed that Pm-TCP4 might promote pistil abortion. Further experiments showed that Pm-miR319a negatively regulates the expression of Pm-TCP4 mRNAs and affected pistil development. Sixteen downstream genes of Pm-TCP4 related to flower development were predicted. Previous studies have shown that they have an impact on the development of pistils. In this study it was established that Pm-miR319a indirectly regulates the development of pistils by regulating its target gene Pm-TCP4.
