Abstract:

The differential expression of Agouti gene mRNA and its encoding ASIP in goat skin with white,black and brown was detected by SYBR Green real-time PCR and Western blotting respectively in order to investigate the regulation mechanism of Agouti gene on coat color.The results indicated that the expression of mRNA was white>black>brown.There was significant difference of mRNA expression between white and brown (P<0.05),and between black and brown (P<0.05).No significant difference of mRNA expression was found between white and black (P>0.05).The ASIP expression was white>brown>black,and the significant difference of ASIP expression was detected between white and black (P<0.05),no significant difference was found between white and brown,and between brown and black.It could be inferred that there might be different regulatory mechanism of Agouti gene in different skin with different coat color.
