Abstract
- 1. The goal of the current study was to evaluate the genetic effects of the vascular endothelial growth factor (VEGF) and its receptor (VEGFR-2) on feather maturity in the Qingyuan partridge chicken, Guangxi sanhuang chicken and Princess chicken. 2. Both SSCP-PCR and qPCR were employed to detect the polymorphism and gene expression of the VEGF and VEGFR-2 genes. 3. Four SNPs were identified in the VEGFR-2 gene. Exon10-A69G was associated with feather maturity (P < 0.01). Princess chickens with the genotype EF had higher feather maturity scores (P < 0.01). Higher expression levels of VEGF and VEGFR-2 were detected in the immature feather group of Qingyuan partridge chickens, especially in the skin. 4. The VEGF and VEGFR-2 genes play critical roles in feather maturity. In addition, exon10-A69G and genotype EF in the Princess chicken could potentially be utilised as genetic markers to improve efficiency in breeding. [ABSTRACT FROM AUTHOR]
