- genetic exchanges among mitochondrial genomes can occur as nonreciprocal gene conversion, rather than exclusively as homologous crossing-over
- on the basis of weighted means of seven mitochondrial genes from rice and maize (and assuming a divergence time of 50 million years), Gaut (4) estimated an absolute rate of 0.33 × 10− 9 synonymous substitutions per site per year
- our independent analysis of 10 mitochondrial genes from rice and maize yields a weighted mean of 0.40 × 10− 9 synonymous substitutions per site per year
