In this study, essential metabolic pathways and candidate genes involved in male sexual improvement were selected from M. nipponense. The methodology involved performing long-read and next generation transcriptome sequencing of genes in the androgenic gland soon after eyestalk ablation. qPCR analysis revealed that the mRNA expression of Mn-IAG was substantially enhanced just after ablation of each the single-side (SS) and double-side (DS) eyestalk, compared together with the control group (CG). The long-read transcriptome generated 49,840 non-redundant transcripts. A total of 1319, 2092 and 4351 differentially expressed genes (DEGs) had been identified between CG versus SS, SS versus DS and CG versus DS, respectively. These information indicated that ablation of your double-sided eyestalk played stronger regulatory roles than the single-side ablation on male sexual development in M. nipponense. This was consistent together with the qPCR evaluation. Cell Cycle, Cellular Senescence, LPAR1 web Oxidative Phosphorylation, Glycolysis/Gluconeogenesis and Steroid Hormone Biosynthesis had been the key enriched metabolic pathways in all three comparisons, and the vital genes from these metabolic pathways had been also chosen. qPCR permitted secondary confirmation of ten DEGs identified by way of RNA-seq. RNAi-mediated silencing analyses of Hydroxysteroid dehydrogenase like 1 (HSDL1) revealed that HSDL1 includes a constructive regulatory effect on testes development. This study gives valuable insight into male sexual development in M. nipponense, such as metabolic pathways and genes, paving the way for sophisticated research on male sexual improvement within this species and in other crustaceans. The oriental river prawn, Macrobrachium nipponense (Crustacea; Decapoda; Palaemonidae), is widely distributed in China as well as other Asian countries1. This species is commercially essential with an annual aquaculture production of 205,010 tons in 20164. Related to other Macrobrachium species, male prawns develop more quickly and reach a bigger size at harvest time2. Hence, male prawns are preferred inside the M. nipponense aquaculture sector. Furthermore, the speedy development of testes in the reproductive season is a further issue restricting the sustainable development of M. nipponense. Preceding studies revealed that the testes of M. nipponense attain sexual maturity within 40 days soon after hatching5. Thus, inbreeding will happen amongst the newborn prawns. Inbreeding will bring about a decrease in ERK2 Storage & Stability resistance to adversity in their offspring, smaller scale of market prawn, in addition to a degradation in germplasm resources. Therefore, it is essential to totally have an understanding of the mechanism of male sexual differentiation and developm.
