Abstract The mitochondrial genome (mtDNA) organization from a fertile revertant line (V3) derived from the maize cytoplasmic male sterile type T (cmsT) callus tissue culture has been determined. We report that the sequence complexity can be mapped on to a circular "master chromosome" of 705 kb which includes a duplication of 165 kb of DNA when compared to its male sterile progenitor. Associated with this event is also a 0.423-kb deletion, which removed the cmsT-associated urf13 gene. As found for the maize normal type (N) and cmsT mitochondrial genomes, the V3 master chromosome also exists as a multipartite structure generated by recombination through repeated sequences.

Configurations of mitochondrial coxI and orfB gene regions were analysed by polymerase chain reaction (PCR) in three wild and one cultivated species of Raphanus. A total of 207 individual plants from 60 accessions were used. PCR with five combinations of primers identified five different amplification patterns both in wild and cultivated radishes. While the mitochondrial DNA (mtDNA) type of Ogura male-sterile cytoplasm was distinguishable from the normal type, the mtDNAs of normal radishes were further classified into four types. The variations were common to wild and cultivated radishes, although contrasting features were found depending on the region of cultivation. These results provide evidence that cultivated radishes have multiple origins from various wild plants of Raphanus.Key words : Raphanus sativus, origin, PCR, mitochondrial coxI.
