Abstract excerpt
Plant mitochondrial (mt) genomes have long been known to evolve slowly in sequence. Here we show remarkable departure from this pattern of conservative evolution in a genus of flowering plants. Substitution rates at synonymous sites vary substantially among lineages within Plantago. At the extreme, rates in Plantago exceed those in exceptionally slow plant lineages by approximately 4,000-fold. The fastest...
