In plants, horizontal transfer of entire plastid, mitochondrial, or nuclear genomes between species generates new combinations of nuclear and organellar genomes, or produces novel species that are allopolyploid. The evolutionary dynamics of plant mitochondrial (mt) genomes have long been known to be unusual compared with those of animals and most other eukaryotes at both the sequence level (exceptionally low rate of point mutations) and structural level (high rates of rearrangement, duplication, genome. The human mitochondrial genome is the entirety of hereditary information contained in human mitochondria. Ensuring continuity of the mitochondrial genome during plant cell dedifferentiation through massive mitochondrial fusion.

The mitochondrial genomes of higher plants are larger than those of animals and form a complex series of linear and circular. Here, we review patterns and processes that shape plant mitochondrial genomes, some relevant interactions between organelles, and the. Palmer jd (1992) comparison of chloroplast and mitochondrial genome evolution in plants. As noted earlier, mitochondrial division and segregation is one of the last events of the tachyzoite cell cycle. They have a high rearrangement but low mutation rate, and a large size.
