英文摘要 | Bighead carp (Hypophthalmichthys nobilis) and silver carp (Hypophthalmichthys molitrix) are genetically close aquaculture fish in the Cyprinidae, which have been confirmed to hold XX/XY sex determination. However, genomic locations of potential sex-related loci in these two fishes are still unknown. In this study, a high-resolution genetic linkage map was constructed by using 2976 SNP and 924 microsatellite markers in a F1 full-sib family of bighead carp, the length of which spanned 2022.34 cM with an average inter-marker distance of 0.52 cM. Comparative genomics revealed a high level of genomic synteny between bighead carp and zebrafish as well as grass carp. QTL fine mapping for sex trait was performed based on this linkage map of bighead carp and an unpublished linkage map of silver carp. A map distance of 3.863 cM (69.787-73.650 cM) on LG19 of bighead carp and 4.705 cM (79.096-83.801 cM) on LG21 of silver carp was significantly associated with sex phenotypes, and these two LGs are homologous between two fish species. Fourteen markers harboring in these regions were in strong linkage disequilibrium with the sex phenotype variance explained (PVE) varying from 89 to 100%. Two common markers were mapped on the QTL regions of bighead carp and silver carp, suggesting that these two carp species may have similar genetic bases for sex determination. Eleven potentially sex-related genes were identified within or near the sex QTL markers in two species. This study provided insights into elucidating mechanisms and evolution of sex determination in cyprinid fishes. |
