Abstract: In order to explore the polymorphism of bone morphogenetic protein receptor ⅠB (BMPR-ⅠB) gene promoter region and its correlation with reproductive traits,three Guizhou local goats,including Qianbei Ma goats,Guizhou Black goats and Guizhou White goats were selected as experimental materials.SNPs were screened by constructing a mixed DNA pool combined with PCR product direct sequencing technology,and various bioinformatics software were used to predict the effects of SNPs on the core promoter region,CpG island and transcription factor binding sites.The results showed that there were 4 SNPs in the promoter region of BMPR-ⅠB gene,which were g.29893005 T > C,g.29893016 C > T,g.29893729 C > G and g.29894370 C > T.The bioinformatics software predicted the core promoter region and CpG island of BMPR-ⅠB gene,and the SNPs site caused the transcription factor binding site to change.The g.29893005 T > C and g.29893016 C > T mutations caused the original transcription factors site binding Sp1 to disappear,g.29893729 C > G mutation caused the original transcription factor binding site AP-1 to disappear,resulting in a new transcription factor binding site USF.g.29894370 C > T mutation produced a new transcription factor binding site C/EBPalp changed the original transcription factor binding site Sp1 to C/EBPalp and Sp1.It was speculated that SNPs might have important effects on regulatory promoter functional elements.
