Mitochondrial genome redundancy in two dinoflagellates
The dinoflagellates Durinskia baltica and Kryptoperidinium foliaceum retain functionally overlapping mitochondria from two evolutionarily distinct lineages
The dinoflagellates Durinskia baltica and Kryptoperidinium foliaceum
are among the most complex cells known to us. They are distinguished by the
presence of a tertiary endosymbiont which, despite significant reduction, still
retains its own nucleus, plastids, and mitochondria. These genome-containing
compartments of the endosymbiont co-exist alongside the nucleus of the host, its
own mitochondria, and an eye spot, which is thought to be the relic of the
original dinoflagellate plastid. These two species, therefore, are almost
unparalleld in their level of complexity, and more specifically in retaining two
evolutionarily distinct mitochondria. This paper investigates this rare
organelle redundancy.
