摘要： A previous study identified slow-tonic S2 tropomyosin and slow tropomyosin isoform as sex-related genes in Macrobrachium nipponense. Their functions were analyzed using RNA interference. However, more than half of the specimens died approximately 8-12 h after injection of the respective double-stranded RNAs (dsRNAs), and HE staining indicated that the heart and gills were the most likely tissues responsible for the resultant deaths. In the current study, we conducted a comparative transcriptomic study of the gills and hearts of M. nipponense to identify potential target genes associated with acute death after dsRNA injection. A total of 68,772 annotated unigenes were generated. In the heart, differentially expressed genes (DEGs) were mainly enriched in glycolysis/ gluconeogenesis and oxidative phosphorylation, while the most relevant pathways in the gills were lysosome, phagosome, and peroxisome. Ten DEGs were screened out and analyzed under lethal hypoxic stress. Among these, fructose 1, 6-biphosphate-aldolase (FBA), glyceraldehyde 3-phosphate dehydrogenase (GDPDH), alcohol dehydrogenase class-3 (ADC3), ATP-synthase subunit 9 (ATPS9), and acid ceramidase-like (ACL) were all differentially expressed under hypoxic conditions. This study shed light on the lethal mechanism caused by interference with tropomyosin genes in M. nipponense, and identifies the related pathways and key genes that could help to improve stress resistance and tolerance in M. nipponense.
