Characterization of myostatin gene (MSTN) of Pekin duck and the association of its polymorphism with breast muscle traits

T. S. Xu, Gu, L. H., Zhang, X. H., Ye, B. G., Liu, X. L., and Hou, S. S., “Characterization of myostatin gene (MSTN) of Pekin duck and the association of its polymorphism with breast muscle traits”, vol. 12, pp. 3166-3177, 2013.

Myostatin, encoded by the MSTN gene, is a negative regulator of muscle growth, and its expression level in muscle tissue is closely correlated with muscle growth and satellite cell proliferation.

Developmental characteristics of pectoralis muscle in Pekin duck embryos

L. H. Gu, Xu, T. S., Huang, W., Xie, M., Shi, W. B., Sun, S. D., and Hou, S. S., “Developmental characteristics of pectoralis muscle in Pekin duck embryos”, vol. 12, pp. 6733-6742, 2013.

To confirm the entire developmental process and transition point of embryonic Pekin duck pectoral muscle, and to investigate the association between pectoral muscle development and their regulating genes, anatomical and morphological analyses of embryonic Pekin duck skeletal muscles were performed, and the expression patterns of its regulating genes were investigated. The anatomical analysis revealed that body weight increased with age, while increases in pectoral muscle weight nearly ceased after the embryo was 20 days of hatching (E20).
