京海黄鸡IGFBP-1基因遗传多态性及其与生长性状的关联分析
Genetic Polymorphisms of the IGFBP-1 Gene and its Relationship with Growth Traits in Jinghai Chicken
摘要
Abstract
Single nucleotide polymorphisms of exon 4 of the chicken IGFBP-1 gene were detected in Jinghai,Arbor Acre,Bian and Youxi chickens by PCR-SSCP. Genetic effects of the IGFBP-1 gene on growth traits of Jinghai chicken were analyzed. Results showed that there were two mutation in the region of exon 4 of IGFBP-1 gene(5550T→C,5692AAT insertion).For primer P3,three genotypes (AA, AB and BB) were detected in Youxi chickens, while the AA and Bian chickens displayed two genotypes (AA and AB), at the same time one genotype(AA) was detected in Jinghai chickens. For primer P4, three genotypes (CC,CD and DD) were detected in four chicken populations. The least square means analysis showed there were significant difference between hatch weight and genotypes(P＜0.05).关键词
