[Genetic polymorphism of HSP70-1 gene and its correlation with resistance to mastitis in Chinese Holstein].

Abstract excerpt

The polymorphisms of HSP70-1 gene in 253 Chinese Holstein dairy cows were studied, and the association between the polymorphisms and somatic cell score (SCS) were analyzed. PCR-SSCP, PCR-RFLP and DNA sequencing were used to investigate mutations in the coding region of HSP70-1 gene. The G-->A-->C mutation at 1 623 bp and G-->A mutation at 2 409 bp were found and both of them were silence mutations that caused no...
