AI Article Synopsis
- Low salinity significantly impacts the population of swimming crabs, making it a crucial environmental factor.
- Researchers utilized quantitative trait loci (QTL) mapping to identify genetic markers linked to low salinity tolerance in these crabs, focusing on linkage group 17 (LG17).
- A total of 95 markers and 79 candidate genes related to low salinity tolerance were identified, providing insights into the genetic basis for salinity adaptation in swimming crabs.
Article Abstract
Low salinity is one of the most important abiotic factors that directly affect the abundance of the swimming crab, . Quantitative trait loci (QTL) mapping could be helpful in identifying the markers and genes involved in low salinity tolerance. In this study, two QTLs of low salt tolerance were mapped on linkage group 17 (LG17, 2.6-5.2 cM) based on a high-density linkage map. Ninety-five markers related to low salinity tolerance were identified association analysis, and seventy-nine low salt-related candidate genes (including ammonium transport, aldehyde dehydrogenase, and glucosyltransferase) were screened from draft genome of the species these markers. This represents the first report of QTL mapping for low salinity tolerance in the swimming crab, which may be useful to elucidate salinity adaptation mechanisms.
