摘要

Calpain 1?(CAPN1) and its activator?HRSP12?are evaluated as candidate gene for quantitative trait loci (QTLs) affecting meat tenderness. In this?study, SNPs were detected by sequencing in 323 cattle from 9 breeds. The association results showed that the A3553G and T824C loci individually related with marbling and tenderness, and?CAPN1/HRSP12?double homozygote and heterozygote/homozygote pairs (AA/TT, AA/CC, AG/TT and GG/TT) had higher marbling score than the other groups. Our findings suggest that polymorphisms inCAPN1?and?HRSP12?might be the important genetic factor influencing meat quality in carcass trait.
