Genomic footprints of a cryptic plastid endosymbiosis in diatoms.
Diatoms and other chromalveolates are among the dominant phytoplankters in the world's oceans. Endosymbiosis was essential to the success of chromalveolates, and it appears that the ancestral plastid in this group had a red algal origin via an ancient secondary endosymbiosis. However, recent analyses have turned up a handful of nuclear genes in chromalveolates that are of green algal derivation...
متن کاملA phylogenomic approach for studying plastid endosymbiosis.
Gene transfer is a major contributing factor to functional innovation in genomes. Endosymbiotic gene transfer (EGT) is a specific instance of lateral gene transfer (LGT) in which genetic materials are acquired by the host genome from an endosymbiont that has been engulfed and retained in the cytoplasm. Here we present a comprehensive approach for detecting gene transfer within a phylogenetic fr...
متن کاملEndosymbiosis: Double-Take on Plastid Origins
Plastids--the light-harvesting machines of plant and algal cells--evolved from cyanobacteria inside a eukaryotic host more than a billion years ago. New data reveal that a mysterious unicellular alga acquired its photosynthetic apparatus much more recently than other eukaryotes, affording a second look at the primary endosymbiotic origin of plastids.
متن کاملPlastid thylakoid architecture optimizes photosynthesis in diatoms
Photosynthesis is a unique process that allows independent colonization of the land by plants and of the oceans by phytoplankton. Although the photosynthesis process is well understood in plants, we are still unlocking the mechanisms evolved by phytoplankton to achieve extremely efficient photosynthesis. Here, we combine biochemical, structural and in vivo physiological studies to unravel the s...
متن کاملPlastid endosymbiosis, genome evolution and the origin of green plants.
Evolutionary relationships among complex, multicellular eukaryotes are generally interpreted within the framework of molecular sequence-based phylogenies that suggest green plants and animals are only distantly related on the eukaryotic tree. However, important anomalies have been reported in phylogenomic analyses, including several that relate specifically to green plant evolution. In addition...
