Comparison and transcriptomic analysis of embryonic leg muscle development differences between Shitou and Wuzong goose.

ABSTRACT: Shitou goose (STE) and Wuzong goose (WZE) are both characteristic goose breeds in Guangdong, China. Their growth cycle is similar, but there are huge differences in body size. One of the reasons for the difference in body size is the individual muscle mass, which is determined by myofiber development. The number of myofibers is fixed as early as the embryonic stage. Therefore, in this study, the leg muscles of 15, 23-day-old geese embryos (E15, E23), and the first day of hatching (P1) goslings of both STE and WZE were selected for analysis. Muscle tissue samples were subjected to histological sectioning and staining for morphological analysis. Differentially expressed genes (DEGs) across developmental stages were identified through systematic screening. An expression map of the identified
