The razor clam Sinonovacula constricta , is one of the most commercially important cultured bivalves in China and Southeast Asia, while S. rivularis is its closer relatives discovered more than a decade ago. In order to obtain offspring with faster growth rate and stronger salt tolerance of S. constricta and S. rivularis , interspecific hybrids were produced, and the hybridity of the interspecific hybrids was confirmed by micr...

The circadian clock is an endogenous regulation mechanism that coordinates biological processes with daily changes, which are regulated by circadian clock genes. Bmal1 and Period are key circadian clock genes and their roles in reproductive development have been widely studied. The spawning time of Sinonovacula constricta is limited to the night even under external artificial stimulation, and it might be regulated by the inter...

Ammonia nitrogen is a common toxic substance in the aquatic system, which seriously threatens the survival and growth of clams. However, less is known about the ammonia metabolism and detoxification strategy in razor clam. In this study, the polymorphism of the Glutamine synthetase gene from Sinonovacula constricta ( Sc-GS ) was found to be related to ammonia tolerance. By comparing the coding sequence (CDS) region of Sc-GS fr...

The razor clam, Sinonovacula constricta is a commercially important bivalve in the western Pacific Ocean, yet little is known about the mechanisms of sex determination/differentiation and gametogenesis. In the present study, the comparative transcriptome analysis of adult gonads (female gonads and male gonads) was conducted to identify potential sex-related genes in S. constricta . The number of reads generated for each target...
