Identification of complete linkage disequilibrium in the DSG4 gene and its association with wool length and crimp in Chinese indigenous sheep

Y. H. Ling, Xiang, H., Zhang, G., Ding, J. P., Zhang, Z. J., Zhang, Y. H., Han, J. L., Ma, Y. H., and Zhang, X. R., Identification of complete linkage disequilibrium in the DSG4 gene and its association with wool length and crimp in Chinese indigenous sheep, vol. 13, pp. 5617-5625, 2014.

The desmoglein 4 (DSG4) gene is a potential candidate in the search for genes that may affect wool traits, because of its function. This study aimed to screen for polymorphisms in partial exon 16 and 3ꞌUTR of the sheep desmoglein 4 DSG4 gene, and to test its possible association with wool length and crimp associated with fur. Overall, 326 sheep were scanned via single-strand conformational polymorphism assay, through three pairs of primers.

Study of the correlation between GH gene polymorphism and growth traits in sheep

J. L. Jia, Zhang, L. P., Wu, J. P., Ha, Z. J., and Li, W. W., Study of the correlation between GH gene polymorphism and growth traits in sheep, vol. 13, pp. 7190-7200, 2014.

The growth hormone gene plays an important role in the physiological function of an organism. The current study aimed to investigate the correlation between polymorphisms in the 5ꞌ regulatory region, exon 4, and 3ꞌ untranslated region (UTR) of the sheep GH gene and sheep growth traits. The DNA from 510 adult sheep was analyzed by DNA sequencing and polymerase chain reaction single-strand conformation polymorphism.
