Abstract

The invention provides SNP molecular markers, primer pairs and a kit of FABP4 gene related to beef quality in Yanbian yellow cattle, and application of the SNP molecular markers, the primer pairs andthe kit, and belongs to the technical field of beef quality screening in yellow cattle. The SNP molecular markers of the FABP4 gene contain a nucleotide sequence of a polymorphism at the 3496 bp as anA / C site, a polymorphism at the 3533 bp as an A / T site, a polymorphism at the 3711 bp as a G / C site, a polymorphism at the 3745 bp as a T / C site and a polymorphism at the 3767 bp as a T / C site of theFABP4 gene. The above five polymorphic sites are located in the third exon, and are in a strong linkage disequilibrium state with similar genetic effects. When the SNP molecular markers are applied to screen breeding fat cattle, fat content and marble pattern are selected as the detection indicators for screening breeding fat cattle while the genotype is heterozygous.

Description

technical field

[0001] The invention belongs to the technical field of yellow beef quality screening, and in particular relates to a FABP4 gene SNP molecular marker related to Yanbian yellow beef quality, a primer pair, a kit and an application thereof. Background technique

[0002] With the continuous improvement of living standards, people have put forward higher requirements for meat quality, not only requiring meat quality to be fresh and tender, but also requiring meat quality to meet the standards of green food. Therefore, countries around the world have conducted extensive research on meat quality. "High-grade beef" and "fattening cattle" have become the current consumption fashion.

[0003] Beef quality involves many indicators, and the definition of high-grade beef is different in each country. Generally, beef with good color, good freshness, high fat content, obvious marble shape, good tenderness and high edible value is called "high-grade beef". Developed countr...
