| Popis: | The past decade has seen the determination of complete mitochondrial genome sequences from a taxonomically diverse set of organisms. These data have allowed an unprecedented understanding of the evolution of the mitochondrial genome in terms of gene content and order, as well as genome size and structure. In addition, phylogenetic reconstructions based on mitochondrial DNA (mtDNA)-encoded protein sequences have firmly established the identities of protistan relatives of the animal, fungal and plant lineages. Analysis of the mtDNAs of these protists has provided insight into the structure of the mitochondrial genome at the origin of these three, mainly multicellular, eukaryotic groups. Further research into mtDNAs of taxa ancestral and intermediate to currently characterized organisms will help to refine pathways and modes of mtDNA evolution, as well as provide valuable phylogenetic characters to assist in unraveling the deep branching order of all eukaryotes. |
