cDNA CLONING AND ANALYSIS OF POLYMORPHISM OF GFI1B GENEIN GUIZHOU WHITE GOAT

摘要

This study mainly aimed to research the CDS sequence (coding sequence), polymorphisms of exon 1, exon 2 and part of exon 8 of GFI1B in GuiZhou white goat of indigenous Chinese goat. The cDNA of GFI1B was analysed through bioinformatics which was obtained by the reverse transcription PCR (RT-PCR). The polymorphisms of GFJIB gene exons region was identified whose association with growth traits was analysed by GuiZhou white goat. The results revealed that the cDNA of GF11B which contained a complete open reading frame (ORF) was 996 bp in full length. The accession numbers on GenBank was JX627316. One new mutation sites of C347A had been determined in the eighth intron. Our results could lay the foundation for the further investigation on the role of GFIIB gene in goat growth traits.
