摘　　要：microRNAs(miRNA)families play a critical role in plant growth,development,and responses to abiotic stress.In this study,we characterized Up-miR-843 and its targets genes in Ulva prolifera responses to nitrogen depravation and heat stress.The data demonstrated that 184 target genes of Up-miR-843 could be successfully validated.N deficiency not heat stress stimulus induced increase in abundance of the Up-miR-843 while exhibited reverse expression of target genes,including cyclin A3 and cyclin L,which were strictly required for cell cycle progression.In addition,U.prolifera with highly expression of Up-miR-843 showed improved biomass,and photosynthesis compared with that under normal growth conditions.Thus,the N deprivation and heat responsive miRNAs might be a possible member mediating the expression of these target genes,which further regulated the growth of U.prolifera.
