摘要: The Xinjiang brown cattle, Red steppe cattle, and Yunling cattle are indigenous cultivated cattle breeds in Chinese frontier provinces, and they produce high-grade beef and milk products, however, their genetic diversity in many important genes related to excellent meat and milk production is still unknown. Our previous studies have found that several candidate genes (e.g., SREBP1c and PAX7) were associated with bovine economically important phenotypic traits, but none has been reported in the above-mentioned three cattle breeds. Since the InDel (insertion/deletion) marker becomes a useful tool applied in the animal molecular breeding, herein, we firstly found that the InDel variations of seven candidate genes in these cattle. Results showed that the genotypic and allelic distributions of these seven genes were remarkably different among these three cattle (p < 0.05 or p < 0.01). Furthermore, the InDel variations of SREBP1c and PAX7 genes were significantly associated with eight phenotypic traits in Xinjiang brown cattle (p < 0.05 or p < 0.01), respectively, suggesting that they can become the useful DNA markers.
