摘要： Background G-protein subunit beta 1 like (GNB1L) encodes a G-protein beta-subunit-like polypeptide. ChickenGNB1Lis upregulated in the breast muscle of high feed efficiency chickens, and its expression is 1.52-fold that in low feed efficiency chickens. However, no report has described the effects ofGNB1Lindels on the chicken carcass and growth traits. Results This study identified a 31-bp indel in the 5 ' untranslated region (UTR) ofGNB1Land elucidated the effect of this gene mutation on the carcass and growth traits in chickens. The 31-bp indel showed a highly significant association with the body weight at 8 different stages and was significantly correlated with daily gains at 0 to 4 weeks and 4 to 8 weeks. Similarly, the mutation was significantly associated with small intestine length, breast width, breast depth and breast muscle weight. Moreover,DDandIDwere superior genotypes for chicken growth and carcass traits. Conclusions These results show that the 31-bp indel ofGNB1Lsignificantly affects chicken body weight and carcass traits and can serve as a candidate molecular marker for chicken genetics and breeding programs.
