In order to verify the relationship between PmmiR319 a and its predicted target gene PmTCP2,and study the role of PmmiR319 a in flower development. The Prunus mume cultivar Daqiandi was used as the experimental material to isolate the Pmm TR319 a precursor sequence and the predicted target gene PmTCP2,and their expression during the flower bud development were analyzed. The relationship between PmmiR319 a and its target gene PmTCP2 was verified with RLM-5'RACE. The results indicated that the PmmiR319 a prec...
