Abstract[English]
The present invention belongs to the technical field of animal genetic engineering, and specifically relates to a method for improving the growth rate of pigs. The method comprises the following steps: fusing, in vivo, a coding region of a GH1 gene with a strong promoter of another endogenous high-expression gene without introducing an exogenous gene to generate a GH1 high-expression gene, wherein the strong promoter is a PSMC5 gene promoter, an ACTA1 gene promoter, an ACTB gene promoter, an NME2 gene promoter or an RPL23 gene promoter. According to the method, pig breeds with a rapid growth rate can be created.[French]
La présente invention se rapporte au domaine technique de l'ingénierie génétique animale, et concerne en particuliuer un procédé pour améliorer le rythme de croissance des porcs. Le procédé comprend les étapes suivantes : fusionner, in vivo, une région codante d'un gène GH1 avec un promoteur fort d'un autre gène endogène à expression élevée sans introduire de gène exogène pour générer un gène GH1 à expression élevée, le promoteur fort étant un promoteur du gène PSMC5, un promoteur du gène ACTA1, un promoteur du gène ACTB, un promoteur du gène NME2, ou un promoteur du gène RPL23. Selon le procédé, des races de porc ayant un rythme de croissance rapide peuvent être créées.[Chinese]
本发明属于动物基因工程技术领域，具体涉及一种提高猪类生长速度的方法。所述方法包括以下步骤：在不引入外源基因的条件下，将GH1基因的编码区与另一内源高表达基因的强启动子体内融合，产生GH1高表达基因，所述强启动子为PSMC5基因启动子、ACTA1基因启动子、ACTB基因启动子、NME2基因启动子或RPL23基因启动子。其能创造出生长迅速的猪类品种。
