Abstract：The solute carrier 6 (SLC6) gene family, known as neurotransmitter transporters, plays a crucial role in stress regulation and osmotic regulation of aquatic organisms. In the present study, the members of the SLC6 gene family of Sinonovacula rivularis (SrSLC6) were identified and analyzed by using bioinformatics methods, and expression patterns under salinity stress were investigated. The results showed that a total of 29 SrSLC6 genes were identified, which belonged to 4 subfamilies and contained 12 conserved motifs and 2 conserved domains SLC6sbd-TauT-like and SLC5-6-like_sbd. Under high and low salinity stress, 16 SrSLC6 gene family members showed different expression responses and their expression levels were up-regulated or down-regulated. Amino acid transporter 4 protein of S. rivularis (SrAAT4) related to salinity adaptation was mainly located in lateral ciliated columnar cells and flat cells on the side of gill filaments, and the expression patterns showed the same trend as transcriptome expression profile, which was significantly decreased at different time points under low salt stress (P<0.05), and significantly increased at different time points under high salt stress (P<0.05). These results indicated that the amino acid transporters (AATs) and neurotransmitter transporters (NTTs) members of SrSLC6 gene family might played important roles in osmotic regulation of S. rivularis, which provided theoretical basis for further research on the osmotic regulation and salinity adaptation of SLC6 gene family in mollusks.
