摘要： Male oriental river prawns (Macrobrachium nipponense) grow faster than females, and therefore, reach larger sizes by harvest time. Histological observations have indicated that the sex-differentiation sensitive period (which includes the formation of the androgenic gland, the testis, and the ovary) is from post-larvae (PL) developmental stage for M. nipponense. In this study, we prepared four microRNA (miRNA) and mRNA libraries using samples collected from sex-differentiation sensitive period (PL7 to PL16) to perform RNA-sequencing for identifying sex-related candidate miRNAs, genes, and metabolic pathways. A total of nine intersection miRNAs were identified, of which three were highly expressed in the androgenic gland, and their expression was verified by quantitative Real-Time PCR (qPCR). These three miRNAs and their 11 predicted target genes may be strong candidates for sex-related miRNAs and sex-related genes in M. nipponense. Five vital sex-related metabolic pathways were also identified that may regulate other sex-differentiation and sex-determination mechanisms. Finding of the study provide important insights to enhance our understanding on sex-differentiation and sex-determination mechanisms for M. nipponense.
