Abstract
Flowering plants have complex mitochondrial genomes that exhibit remarkable plasticity in size and structure. Their recombinogenic nature contributes to a mosaic of DNA sequences, both endogenous and exogenous in origin. This review focuses on the effects that DNA rearrangements have on the organization, structure, and expression of mitochondrial genes in both normal and mutant plants. The association of mitochondrial DNA recombinational events with the phenomenon of cytoplasmic male sterility is highlighted. Key words: chimeric genes, cytoplasmic male sterility, DNA rearrangements, gene expression, genome evolution, mitochondrial genes, nuclear restorer genes.Keywords
