AIR: A batch-oriented web program package for construction of supermatrices ready for phylogenomic analyses
The AIR program package allows for efficient creation of multigene alignments and better assessment of evolutionary rates in sequence alignments, resulting in improved phylogenetic resolution and increased statistical support for branching patterns among the early diverging eukaryotes.
Phylogenomics Reshuffles the Eukaryotic Supergroups
This work reports the sequencing of expressed sequence tags for two species belonging to the supergroup Rhizaria and presents the analysis of a unique dataset combining 29908 amino acid positions and an extensive taxa sampling made of 49 mainly unicellular species representative of all supergroups.
Phylogenomics reveals a new ‘megagroup’ including most photosynthetic eukaryotes
This work investigates early evolution among the major eukaryotic supergroups using the broadest multigene dataset to date and provides strong support for the clustering of plants, chromalveolates, rhizarians, haptophytes and cryptomonads, thus linking nearly all photosynthetic lineages and raising the question of a possible unique origin of plastids.
Patterns of Rare and Abundant Marine Microbial Eukaryotes
Multigene Phylogeny of Choanozoa and the Origin of Animals
Animals are evolutionarily related to fungi and to the predominantly unicellular protozoan phylum Choanozoa, together known as opisthokonts. To establish the sequence of events when animals evolved
Marine protist diversity in European coastal waters and sediments as revealed by high-throughput sequencing.
This extensive and systematic sequencing of geographically separated sites provides the most comprehensive molecular description of coastal marine protist diversity to date.
Phylogenetic analyses indicate that the 19'Hexanoyloxy-fucoxanthin-containing dinoflagellates have tertiary plastids of haptophyte origin.
Analyses of SSU rDNA from the plastid and the nuclear genome of these dinoflagellate species indicate that they have acquired their plastids via endosymbiosis of a haptophyte, and distance, parsimony, and maximum-likelihood phylogenetic analyses of plastido rRNA gene sequences place the three species within the haptophical clade.
