In this study, 1,800 turbot (Scophthalmus maximus) individuals from 30 full‐sib families were experimentally infected with Vibrio anguillarum, and the expression levels of the immune factors lysozyme, hepcidin, heat‐shock protein 70 (HSP70), HSP90, immunoglobulin M (IgM), C‐type lectin and Lily‐type lectin in the liver were measured by real‐time PCR. Heritability values of the seven immune factors were 0.289 ± 0.087, 0.092 ± 0.024, 0.282 ± 0.043, 0.244 ± 0.027, 0.343 ± 0.081, 0.092 ± 0.011 and 0.084 ± 0.009, respectively. The ranges of phenotypic, genetic and environmental correlations were –0.889 to 0.759, –0.841 to 0.888 and –0.919 to 0.883, respectively. The heritability values of HSP70, HSP90 and IgM were moderate, and the genetic correlations between HSP70, HSP90 and IgM were moderate to highly positive, which suggests that the immunocompetence of turbot against V. anguillarum can be improved by genetically improving these three immune characters via multi‐trait integrated breeding technology or indirect selection.

鳗弧菌感染的大菱turbo中7种免疫因子的遗传参数

在这项研究中，实验性地感染了来自30个全同胞家族的1800尾大S（Scophthalmus maximus），并感染了鳗弧菌，并表达了免疫因子溶菌酶，肝素，热休克蛋白70（HSP70），HSP90，免疫球蛋白M的表达水平。通过实时PCR检测肝脏中的IgM，C型凝集素和Lily型凝集素。七个免疫因子的遗传值分别为0.289±0.087、0.092±0.024、0.282±0.043、0.244±0.027、0.343±0.081、0.092±0.011和0.084±0.009。表型，遗传和环境相关性的范围分别为–0.889至0.759，–0.841至0.888和–0.919至0.883。HSP70，HSP90和IgM的遗传力值适中，并且HSP70，HSP90和IgM之间的遗传相关性为中等至高度阳性，这表明可以通过遗传改良这三种免疫特性来提高大菱turbo抗鳗弧菌的免疫能力。多性状综合育种技术或间接选择。
