Abstract BackgroundNitrite is a major environmental toxin in aquaculture systems disrupting multiple physiological functions in aquatic animals. Although nitrite tolerance in shrimp is closely related to successful industrial production, few genetic studies of this trait are available. ResultsIn this study, we constructed a high-density genetic map of L. vannamei with 17,242 single nucleotide polymorphism markers spanning 6,828.06 centimorgans (cM) and an average distance of 0.4 cM between adjacent markers on 44 linkage groups (LGs). Using this genetic map, we identified 2 quantitative trait loci (QTLs) involved in nitrite tolerance on two LGs explaining 8.42–10.31% of the phenotypic variance. We then sequenced the transcriptomes of the most nitrite-tolerant and the most nitrite-sensitive individuals from each of four genetically distinct L. vannamei families and found 2,002, 1,983, 1,954, and 1,867 differentially expressed genes in the four families, respectively. By integrating QTL and transcriptomics analyses, we identified a candidate gene associated with nitrite tolerance. This gene was annotated as solute carrier family 26 member 6 (SLC26A6). RNA interference (RNAi) analysis demonstrated that SLC26A6 was critical for nitrite tolerance in L. vannamei. ConclusionsThe present study increases our understanding of the molecular mechanisms underlying nitrite tolerance in shrimp, and provides a basis for molecular-marker-assisted shrimp breeding.
