摘要： This study aimed to investigate the role of the LCORL gene in regulating the growth performance of Zhedong white (ZDW) geese, belonging to the swan geese (Anser cygnoides), and identify possible selective signatures in diverse goose breeds. Single nucleotide polymorphisms around LCORL were genotyped, and their associations with body-size-related (BSR) traits were estimated. The results showed that the genotyped loci upstream of LCORL were significantly related to the body weight and breast width of ZDW geese aged 10 weeks (p < 0.05). A genome scan comparing expected heterozygosity among different breeds identified a similar to 150 kb long genomic region with extremely low heterozygosity downstream of LCORL among swan geese. Further, significant associations of variants within the low heterozygosity region among ZDW geese with BSR traits, including body weight, body length and breast width (p < 0.05) were also detected. Overall, mutations adjacent to LCORL were related to the growth performance of swan geese, and the significant effects of variants in a low-heterozygosity region on BSR traits provided valuable insights into the molecular mechanism of artificial selection reshaping body stature in swan geese.
