Abstract
The atp6 gene is an important mitochondrial functional gene.The studies on some plant species showed that RNA editing of atp6 gene was related to the cytoplasmic male sterility.In this paper,the comparative studies of RNA editing of atp6 gene between the cytoplasmic male sterile line NJCMS1A and its maintainer line NJCMS1B in soybean(Glycine max L.Merr.) were conducted.The results showed that two editing sites were found on the conservative region of the atp6 gene of NJCMS1A and NJCMS1B,but the two editing sites of the atp6 gene of NJCMS1A were different from those of NJCMS1B,and led to the different changes of amino acid.The results of the mtDNA sequence comparision showed that one base difference was found in the conservative region of atp6-3 gene between NJCMS1A and NJCMS1B.In addition,the obvious difference was found on the expression of atp6-1,atp6-2 and atp6-3 between NJCMS1A and NJCMS1B.
