| 摘 要： | 采用190个微卫星分子标记对罗非鱼282个全同胞个体进行数量性状位点(QTL)定位,获得15个罗非鱼耐盐QTL,其中st-c、mst-a可分别解释19.2％的两性耐盐差异和19.1％的雄性耐盐差异,XY性别决定位点、钠钾氯协同转运蛋白2(NKCC2)基因分别定位于st-c、mst-a的峰值处.研究结果表明,罗非鱼海水养...

| Abstract: | 190 microsatellite markers were used to perform QTL mapping in 282 full sib tilapia individuals,and 15 salt-tolerant QTLs were identified.Among them,st-c and mst-a could explain 19.2%of the difference in salt tolerance among all fish and 19.1%of the difference in salt tolerance among males,respectively.One XY sex-determining locus and sodium potassium chloride cotransporter 2(NKCC2)gene were located at the peaks of st-c and mst-a,respectively.The results indicated that all male tilapia may have salt tolerance advantage in mariculture,and NKCC2 could be an important candidate gene in the breeding of salt-tolerant tilapia. |
