| Abstract: | Summary The complete physical map of the mitochondrial genome of the Owen cytoplasm of sugar beet has been determined from overlapping cosmid clones. The genome is 386 kb in size and has a multicircular organisation generated by homologous recombination across repeated DNA elements. The location of the rRNA genes and several polypeptide genes has been determined. In addition the mitochondrial genome was found to contain a sequence of chloroplast DNA including part of the 16 S rRNA gene. |
