| Abstract: | Cytoplasmic male sterile (CMS) plants were obtained by asymmetrical protoplast fusion between red cabbage (fertile) and normal radish (fertile). The CMS plants showed restriction fragment length polymorphism (RFLP) patterns of mitochondrial (mt) DNA that were different from those of both parental lines. PCR analysis of mtDNA of the CMS plants and though Southern blot analysis showed that the mtDNA of the CMS line had the characteristics of the ogura CMS type. The results suggested that the orf138 gene and the ogura type atp6 gene are present in normal fertile cabbage and radish at a low copy level. This revised version was published online in July 2006 with corrections to the Cover Date. |
