Cloning and Phylogenetic Analysis of Mitochondrial Cytochrome b Gene from Soybean ( Glycine max)
摘要
Abstract
In this study, mitochondrial DNA uncompleted sequence was used to design special prime of mitochondrial cyto-chrome b gene(cob)and obtained conservation domain of soybean cob gene by PCR amplification. The results showed that cob gene was consisted by 1 173 bp which encoded 391 amino acids,with 58.1% A +T and 41.9% G + C content. Southern blot analysis revealed that more than 2 cob gene copies were found in G. Max mitochondrial genome. Amino acid sequence and phy-logenetic analysis showed that cob was most similar to the dicotyledon,with 98% identity at the nucleotide level. In conclusion, cob gene is a potential hereditary marker for phyletic classification basing on its highly conservative property.关键词
