“…Chloroplast genome analysis (Ishii et al 2001;Hirosawa et al 2004;Goryunova et al 2010), mitochondrial genome fingerprinting (Breiman 1987;Terachi and Tsunewaki 1992;Wang et al 2000), and phenotypic effect of each cytoplasm type in the alloplasmic condition were further used for classification and evolutionary studies among these species (Tsunewaki 2009). In the present study, we isolated and sequenced ATP6-1 and ATP6-2 from several alloplasmic and euplasmic lines in this group of species to discern the evolutionary patterns of this region.…”

Mutation and chromosomal rearrangements are the two main forces of increasing genetic diversity for natural selection to act upon, and ultimately drive the evolutionary process. Although genome evolution is a function of both forces, simultaneously, the ratio of each can be varied among different genomes and genomic regions. It is believed that in plant mitochondrial genome, rearrangements play a more important role than point mutations, but relatively few studies have directly addressed this phenomenon. To address this issue, we isolated and sequenced the ATP6-1 and ATP6-2 genes from 46 different euplasmic and alloplasmic wheat lines. Four different ATP6-1 orthologs were detected, two of them reported for the first time. Expression analysis revealed that all four orthologs are transcriptionally active. Results also indicated that both point mutation and genomic rearrangement are involved in the evolution of ATP6. However, rearrangement is the predominant force that triggers drastic variation. Data also indicated that speciation of domesticated wheat cultivars were simultaneous with the duplication of this gene. These results directly support the notion that rearrangement plays a significant role in driving plant mitochondrial genome evolution.
