Genotypes of the nucleotide substitution g.23655332G>C of SNP marker rs385360448 at Lysophospholipase I (LYPLA1) gene intron 7, were tested for their effect on the carcass traits of Hanwoo and Jeju Crossbred cattle (F1 progeny produced between Hanwoo × Jeju Black cattle) populations on Jeju Island. In the Hanwoo steer population, the meats containing LYPLA1 rs385360448 G/- genotypes showed significantly higher marbling scores and greater texture indices, compared to those of rs385360448 C/C homozygous animals (p<0.05). However, the LYPLA1 genotypes were not associated with the levels of carcass weight, backfat thickness, eye muscle area (EMA), meat color, and fat color (p>0.05). On the other hand, in the JCC steer population, the LYPLA1 G/- harboring meats showed significantly greater EMA levels, compared to those of C/C homozygotes (p<0.05). The results of the present study indicate that the LYPLA1 genotypes could alter the levels of intramuscular fat deposition, texture index, and eye muscle area via phospholipid metabolism in the Longissimus dorsi muscle of the cattle. These findings suggested that LYPLA1 genotypes may effect molecular genetic markers in the improvement of carcass traits of Hanwoo and Jeju Black industrial cattle populations on Jeju Island.
