Abstract:

【Objective】 The relationship between porcine DNA polymorphisms of POU1F1 and mRNA expression was studied. 【Method】 The intron 1, a partial regional polymorphisms of porcine POU1F1 of two breeds of Yorkshare and Zhongxu black, were investigated by PCR-SSCP. Based on the total RNA contracted from animals pituitary, the mRNA quantities of POU1F1, GH, PRL, and TSH-? were masured by RQ-PCR. 【Result】 It was found that a SNP of T→C in intron 1 (site 1515bp), markedly correlated with the daily weight gain (R=-0.6, P＜0.05) and the expression of GH (P＜0.05) before slaughtering. 【Conclusion】The SNP of T→C led to the increase of the GH expression; But the daily weight gain decreasd in the growth trait before slaughtering.

Key words: POU1F1, PCR-SSCP, polymorphisms, SNP
