AANAT基因编码区多态性与家兔生长性状的关联分析
Association Analysis between Polymorphism of Coding Sequence of AANAT Gene and Growth Traits of Rabbits
摘要
Abstract
To study the association between Coding sequence(CDS)of five HT-N-acetyltransferase gene (AANAT) polymorphism and growth traits in rabbits.In the study we used direct sequencing method to detect single nucleotide polymorphism of exons of AANAT gene region with Tianfu black rabbit,IRA rabbit and New Zealand rabbit as experimental materials.There were 5 complete linkage mutation sites(C.132 T＞C,C.153T＞C,C.159 A＞T,C.234 A＞G,C.291A＞G) in the CDS ofAANAT gene in the three rabbit breeds.3 genetypes(wild type:TTTTAAAAAA,heterozygous:TCTCATAGAG mutant type:CCCCTTGGGG) were formed.In New Zealand,the 56,70 and 84 days body weight of mutant type was significantly higher than those of other types rabbits and in the IRA rabbit and Tianfu black rabbit (P＜0.05),70 and 84 days body weight were higher (P＜0.05).The AANAT gene can be used as a candidate gene for growth traits in rabbit.关键词
