PCR–SSCP and DNA sequencing methods were employed to screen the genetic variation of vascular endothelial growth factor (VEGF) gene in 675 individuals belonging to three Chinese indigenous cattle breeds including Qinchuan (QC), Jiaxian Red (JX) and Nanyang (NY) breed. Three new single nucleotide polymorphisms (SNPs) (g.6765T > C ss130456744, g.6860A > G ss130456745, g.6893T > C ss130456746) were found. One SNP (g.6765T > C) was detected in intron II of VEGF gene in all three breeds and the other two SNPs (g.6860A > G, g.6893T > C) were in exon III of VEGF gene only in NY breed. Among them, two synonymous mutations of exon III were identified: CCA (Pro) > CCG (Pro) at position 65th amino acid (aa) and TGT (Cys) > TGC (Cys) at position 76th aa of VEGF(190aa) in NY breed. Our study revealed that NY breed exhibited the most abundant genetic diversity in VEGF gene within the three cattle breeds. Furthermore, JX cattle breed was more similar to QC breed than to NY breed. Our genetic data in the present study supported the hypothesis that the distribution pattern of Chinese indigenous cattle breeds was closely related to the geographical and climatic background again.
