Abstract

Repeated sequences known as recombination repeats are present in the majority of plant mitochondrial genomes. Two recombination repeat sequences from Petunia have been analyzed. The two repeats are virtually identical over 1.42 kb. One of the repeats is truncated and is likely to have arisen from a rare recombination event in the full-length repeat. Two sequence-blocks within the Petunia repeat are highly similar to sequences in the 5' flank of several plant mitochondrial genes. No sequence motifs are shared by the Petunia repeat and other sequenced plant mitochondrial recombination repeats, suggesting that the recombination occurs by an homologous, rather than a site-specific, mechanism.
