The Marine Microbial Eukaryote Transcriptome Sequencing Project (MMETSP): Illuminating the Functional Diversity of Eukaryotic Life in the Oceans through Transcriptome Sequencing
TLDR
This Community Page describes a resource of 700 transcriptomes from marine microbial eukaryotes to help understand their role in the world's oceans. Expand
The Puzzle of Plastid Evolution
TLDR
New models of plastid evolution involving ancient secondary and tertiary endosymbioses are needed to explain the full spectrum of photosynthetic eukaryotes. Expand
Endosymbiosis and Eukaryotic Cell Evolution
TLDR
Modern views on endosymbiotic theory in a historical context are framed, highlighting the transformative role DNA sequencing played in solving early problems in eukaryotic cell evolution, and posing key unanswered questions emerging from the age of comparative genomics. Expand
Lateral gene transfer and the evolution of plastid-targeted proteins in the secondary plastid-containing alga Bigelowiella natans
TLDR
The results underscore the importance of lateral gene transfer in contributing foreign proteins to eukaryotic cells and their organelles, and also suggest that its impact can vary from lineage to lineage. Expand
Complex protein targeting to dinoflagellate plastids.
TLDR
An expressed sequence tag survey of the peridinin-plastid containing din oflagellate Heterocapsa triquetra is conducted to identify and characterize numerous targeting presequences of plastid proteins encoded in the nucleus, suggesting that two mechanisms, perhaps even trafficking routes, may direct proteins to dinoflageLLate plastids. Expand
MKKS/BBS6, a divergent chaperonin-like protein linked to the obesity disorder Bardet-Biedl syndrome, is a novel centrosomal component required for cytokinesis
TLDR
The findings provide the first insight into the nature and cellular function of BBS6, and shed light on the potential causes of several ailments, including obesity, retinal degeneration, kidney dysfunction and congenital heart disease. Expand
Diversity, nomenclature, and taxonomy of protists.
TLDR
Evaluating placental inter-ordinal phylogenies with novel sequences including RAG1, γ -fibrinogen, ND6, and mt-tRNA, plus MCMC-driven nucleotide, amino acid, and codon models, plus a phylogenetic foundation for comparative mammalian genomics is evaluated. Expand
Recurrent paralogy in the evolution of archaeal chaperonins
TLDR
A third chaperonin-encoding gene (TF55-gamma) is described from two Sulfolobus species; phylogenetic analyses indicate that the gene duplication producing TF55-Gamma occurred within crenarchaeal evolution. Expand
Plastid genome sequence of the cryptophyte alga Rhodomonas salina CCMP1319: lateral transfer of putative DNA replication machinery and a test of chromist plastid phylogeny.
TLDR
The plastid genome of Rhodomonas salina CCMP1319 is sequenced and it possesses interesting features not seen in the distantly related cryptophyte Guillardia theta or in other red secondary plastids, including pseudogenes, introns, and a bacterial-derived gene for the tau/gamma subunit of DNA polymerase III (dnaX), the first time putative DNA replication machinery has been found encoded in any plastID genome. Expand
Algal genomes reveal evolutionary mosaicism and the fate of nucleomorphs
TLDR
The nuclear genomes of the cryptophyte Guillardia theta and the chlorarachniophyte Bigelowiella natans are sequenced and extensive genetic and biochemical mosaicism is revealed, with both host- and endosymbiont-derived genes servicing the mitochondrion, the host cell cytosol, the plastid and the remnant endosYmbionT cytOSol of both algae.
