Polymorphisms of the bovine growth differentiation factor 9 gene associated with superovulation performance in Chinese Holstein cows

K. Q. Tang, Yang, W. C., Li, S. J., and Yang, L. - G., Polymorphisms of the bovine growth differentiation factor 9 gene associated with superovulation performance in Chinese Holstein cows, vol. 12, pp. 390-399, 2013.

Growth differentiation factor 9 (GDF9) belongs to the transforming growth factor β superfamily and plays a critical role in ovarian follicular development and ovulation rate. We examined the bovine GDF9 gene polymorphism and analyzed its association with superovulation performance. Based on the sequence of the bovine GDF9 gene, six pairs of primers were designed to detect single nucleotide polymorphisms of two exons and intron 1 of GDF9 using polymerase chain reaction-single-strand conformation polymorphism.
