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.

Genes for the cytoskeletal protein tubulin in the bacterial genus Prosthecobacter
TLDR
It is predicted that the Prosthecobacter tubulins are monomeric, unlike eukaryotic α and β tubulinins, which form dimers and are therefore unlikely to form microtubule-like structures.

Characterization and Evolution of Cell Division and Cell Wall Synthesis Genes in the Bacterial Phyla Verrucomicrobia, Lentisphaerae, Chlamydiae, and Planctomycetes and Phylogenetic Comparison with…
TLDR
Comprehensive sequence analyses of available genome data for representatives of Verrucomicrobia, Lentisphaerae, Chlamydiae, and Planctomycetes strongly indicate that their last common ancestor possessed a conserved, ancestral type of dcw gene cluster and an FtsZ-based cell division mechanism.

A Multidisciplinary Approach to Describe Protists: Redescriptions of Novistrombidium testaceum Anigstein 1914 and Strombidium inclinatum Montagnes, Taylor, and Lynn 1990 (Ciliophora, Oligotrichia)
TLDR
The 18S rDNA molecular data, in accordance with morphological and ultrastructural observations, indicate that the Strombidiida (Oligotrichia) constitute a well-supported clade and is recommended that when possible, ecologists, morphological taxonomists, and molecular biologists combine their expertise to provide comprehensive taxonomic descriptions.

Microtubules in Bacteria: Ancient Tubulins Build a Five-Protofilament Homolog of the Eukaryotic Cytoskeleton
The unequivocal identification of microtubules in bacteria throws light on the evolution of modern eukaryotic microtubules from a primordial structure.

The Passive Yet Successful Way of Planktonic Life: Genomic and Experimental Analysis of the Ecology of a Free-Living Polynucleobacter Population
TLDR
Experiments indicated that these bacteria live as chemoorganotrophs by mainly utilizing low-molecular-weight substrates derived from photooxidation of humic substances, which resulted in a highly passive lifestyle so far only known among free-living bacteria from pelagic marine taxa dwelling in environmentally stable nutrient-poor off-shore systems.

Defensive extrusive ectosymbionts of Euplotidium (Ciliophora) that contain microtubule-like structures are bacteria related to Verrucomicrobia.
TLDR
The prokaryotic vs. eukaryotic nature of epixenosomes was resolved by comparative sequence analysis of amplified small subunit rRNA genes and in situ hybridization with fluorescently labeled rRNA-targeted polynucleotide probes.

A molecular approach to the tangled intrageneric relationships underlying phylogeny in Euplotes (Ciliophora, Spirotrichea).
TLDR
Small subunit rRNA sequences of 11 morphologically defined species colonizing different habitats were determined and pointed to a high divergence between this genus and the other Spirotrichea, together with a high variability within the genus Euplotes.

“Candidatus Midichloriaceae” fam. nov. (Rickettsiales), an Ecologically Widespread Clade of Intracellular Alphaproteobacteria
TLDR
It is suggested that aquatic/environmental protista have acted as evolutionary reservoirs for members of this novel family, from which one or more lineages with the capacity of infecting metazoa have evolved.
