Description
Porcine meat production is determined by total myofiber number, while during embryonic stages, total myofiber number is determined by primary myofiber number. Thus, primary myofiber is a crucial determinant factor of porcine adult meat production. Understanding the molecular mechanisms of distinct primary myofiber formation time in pig breeds with different meat production will help to improve pig meat production by genetic methods and benefit the researches concerning muscle development. In this study RNA-seq to uncover the molecular mechanisms of distinct primary myofiber formation time in pig breeds with different meat production (Landrace and Wuzhishan) by using longissimus dorsi muscle (LDM) samples during 3 early embryonic stages (18,21,28 dpc).
