- Abstract
- The present study was undertaken to find out novel single nucleotide polymorphism (SNPs) and to analyze the association between SNPs of OCX-32 gene and egg production traits, in the four Korean native chicken breeds (Ogol, black, gray, and white). Twenty-one variations (16 SNPs and 5 INDELs) in the intronic region of the OCX-32 gene were detected, including new 9 variants (1500T > A, 1504A > G, 1658A > G, 1668A > T, 1821A > C, 1234 del A, ins CTT, ins TTC, and 1681 del T) in the chicken population (n=120). Fifteen variations (1346A > G, 1373G > A, 1399T > C, 1446C > G, 1500T > A, 1504A > G, 1522G > A, 1530T > A, 1563G > A, 1668A > T, 1743G > T, 1772T > A, 1821A > C, ins TTC, and ins TCT) showed significant association with egg production ratio, weight and age in the chickens. Conclusively, the result obtained suggested that SNPs and INDELs of the OCX-32 gene might be useful as genetic markers for egg production traits in breeding program of the Korean native chicken.
