To determine the origin of Ogura male sterile cytoplasm in radish (Raphanus sativus L.), wild and cultivated radishes were crossed. Three types of progeny resulted from the F1 hybrids between the wild radish from 'Kushikino' with Ogura-type mtDNA and the cultivars ('Uchiki-Gensuke' or 'Comet'). The
Ogura male-sterile cytoplasm was surveyed in common Japanese radish cultivars and in wild radishes growing in various localities in Japan. Mitochondrial (mt) DNA rearrangement involving the atp6 gene was used as a molecular marker. To detect the mtDNA rearrangement, polymerase chain reactions (PCR)
orf224 is a novel reading frame present upstream of the atp6 gene in the mitochondria of "Polima" cms cytoplasm of rapeseed. In order to determine the origin of orf224, the sequences homologous to orf224 were isolated and characterized. Sequence analysis indicated that orf224 originated by recombina
