Detection method and application of goat atbf1 gene single nucleotide polymorphism

Abstract

The invention discloses a method for detecting the single-nucleotide polymorphism of a goat ATBF1 gene and the application of the goat ATBF1 gene. According to the method, the goat whole-genome DNA to be tested is taken as a template, the goat ATBF1 gene is amplified by use of the PCR technology, the PCR product is digested by use of a restriction enzyme MspI or HpaII, next, the agarose gel electrophoresis is performed, and the genotype of No.25748nt or No.163517nt SNP of the goat ATBF1 gene is identified according to the electrophoresis result; different genotypes of the No.25748nt and No.163517nt SNPs of the ATBF1 gene have remarkable relevance with the growth and development traits of the goat, and therefore, the ATBF1 gene is advantageous for quickly establishing a good goat genetic resource population.

Description

technical field [0001] The invention belongs to the field of animal molecular breeding, and relates to a method for detecting single nucleotide polymorphism (SNP) of an important functional gene and its application, in particular to a method for detecting the single nucleotide polymorphism of goat ATBF1 gene and its application in breeding. application. Background technique [0002] Animal breeding technology mainly includes conventional breeding technology based on phenotype and phenotypic value and molecular breeding technology based on DNA polymorphism. As an important part of the molecular breeding technology system, marker-assisted selection (MAS) breeding technology first detects DNA polymorphisms of important genes, then analyzes the correlation between DNA polymorphisms and genetic traits, and finally Trait selection based on DNA markers significantly associated with genetic traits. As a new technology born during the development of modern molecular biology technol...
