| Abstract: | Physical maps of the cobmtDNA region were constructed and compared between sugar beet Beta vulgarisL. plants with normal fertility and with cytoplasmic male sterility (CMS). A CMS-associated rearrangement did not affect the coding region of coband combined two mtDNA regions which are normally about 150 kb apart. Two point substitutions were found in the 3"-untranslated region of cob. |
