Multiple Independent Changes in Mitochondrial Genome Conformation in Chlamydomonadalean Algae.

ABSTRACT: Chlamydomonadalean green algae are no stranger to linear mitochondrial genomes, particularly members of the Reinhardtinia clade. At least nine different Reinhardtinia species are known to have linear mitochondrial DNAs (mtDNAs), including the model species Chlamydomonas reinhardtii. Thus, it is no surprise that some have suggested that the most recent common ancestor of the Reinhardtinia clade had a linear mtDNA. But the recent uncovering of circular-mapping mtDNAs in a range of Reinhardtinia algae, such as Volvox carteri and Tetrabaena socialis, has shed doubt on this hypothesis. Here, we explore mtDNA sequence and structure within the colonial Reinhardtinia algae Yamagishiella unicocca and Eudorina sp. NIES-3984, which occupy phylogenetically intermediate positions between species with o
