With the advent of global climate change, heat-tolerance is becoming more and more important to the sustainability of animal husbandry production systems. Previous studies have shown that MYO1A gene associated with pigmentation may be closely related to heat-tolerance in cattle. In this study, a novel missense mutation (NC_037332.1 g.56390345 A > G) was first detected in MYO1A in 891 individuals of 35 cattle breeds, which transformed the amino acid isoleucine into valine. The purpose of...

Previous studies have shown that the feather growth rate of chicks is determined by two alleles located on the sex chromosome Z; however, in chicken production, feathering is usually not consistently controlled by the sex chromosome. To identify whether the feathering rate is related to autosomal inheritance, whole-genome resequencing was performed in eight chickens with slow- and fast-feathering rate. A total of 54,984 autosomal single nucleotide polymorphisms (SNPs) were identified, including 393 and 376 exonic...
