狼山鸡保种群不同世代MHC BF基因遗传多样性研究
Genetic Diversity of MHC BF Gene in Different Generations of Langshan Conserved Population
摘要
Abstract
The MHC BF1 and BF2 loci polymorphisms of different generations (G0,G5,G10,G12,G14,G15,G17) were analyzed by illumina platform Miseq re-sequencing,and revealed the genetic diversity of MHC BF gene between different generations of Langshan chicken,in order to provide a scientific basis for better monitoring of the conservation effect.There were 59 and 34 SNPs ofMHC BF1,BF2 gene identified in seven generations.Ho,He and PIC ofMHC BF1 gene in generations G12,G14,and G15 remained stable.There were differences in different generations for Ho of MHCBF1 gene,with generations G17＞G15＞G14,G12,G10＞G5＞G0.There were differences in different generations for He and PIC of MHC BF1 gene,with generations G17,G15＞G14,G12,G10＞G5＞G0.Ho ofMHC BF2 gene in generations G10,G14 and G15 remained stable.There were differences in different generations for Ho ofMHC BF2 gene,with generations G17,G12＞G15,G14,G10＞G5,G0.He and PIC ofMHC BF2 gene in generations G12,G14 and G15 remained stable.There were differences in different generations for He and PIC ofMHC BF2 gene,with generations G17,G15,G14,G12＞G10＞G5,G0.The results showed that the genetic diversity of MHC BF1 and BF2 were different in different generations,but the overall law was in accordance with the hypothesis of the choice of fluctuation (choice of spatiotemporal transformation).The genetic diversity of the MHC BF gene became more abundant over time,and the genetic diversity remained stable in some successive generations,which may be related to the MHC BF gene function.关键词
