The results provide further evidence that natural populations of Prochlorococcus and Synechococcus consist of multiple coexisting ecotypes, genetically closely related but physiologically distinct, which may vary in relative abundance with changing environmental conditions.
Triploblastic relationships with emphasis on the acoelomates and the position of Gnathostomulida, Cycliophora, Plathelminthes, and Chaetognatha: a combined approach of 18S rDNA sequences and…

For the first time, a data analysis recognizes a clade of acoelomates, the Platyzoa, which is expanded to include the enigmatic phylum Cycliophora, as sister group to Syndermata.
Rapid Diversification of Marine Picophytoplankton with Dissimilar Light-Harvesting Structures Inferred from Sequences of Prochlorococcus and Synechococcus (Cyanobacteria)

Standard phylogenetic methods and newer algorithms insensitive to such biases did not recover different branching patterns within the marine picophytoplankton group, and failed to cluster Prochlorococcus with chloroplasts or other chlorophyll b-containing prokaryotes.
Cyclin: A protein specified by maternal mRNA in sea urchin eggs that is destroyed at each cleavage division
Fine-scale phylogenetic architecture of a complex bacterial community
It is proposed that such microdiverse clusters arise by selective sweeps and persist because competitive mechanisms are too weak to purge diversity from within them, indicating a large predominance of closely related taxa in this community.
Genotypic Diversity Within a Natural Coastal Bacterioplankton Population
This work shows that this group of coastal bacterioplankton consists of at least a thousand distinct genotypes, each occurring at extremely low environmental concentrations (on average less than one cell per milliliter), and shows extensive allelic diversity and size variation.

The coexistence of two phylogenetically distinct symbiont species within a single cell, a condition not previously known in any metazoan, is demonstrated in the gills of a Mid-Atlantic Ridge…
High-resolution quantitative imaging of mammalian and bacterial cells using stable isotope mass spectrometry
MIMS makes it possible for the first time to both image and quantify molecules labeled with stable or radioactive isotopes within subcellular compartments.
Teredinibacter turnerae gen. nov., sp. nov., a dinitrogen-fixing, cellulolytic, endosymbiotic gamma-proteobacterium isolated from the gills of wood-boring molluscs (Bivalvia: Teredinidae).

A cellulolytic, dinitrogen-fixing bacterium isolated from the gill tissue of a wood-boring mollusc (shipworm) Lyrodus pedicellatus and 58 additional strains with similar properties, isolated from gills of 24 bivalve species representing 9 of 14 genera of Teredinidae, are described.
Sulfur-oxidizing bacterial endosymbionts: analysis of phylogeny and specificity by 16S rRNA sequences
The 16S rRNAs from the bacterial endosymbionts of six marine invertebrates from diverse environments were isolated and partially sequenced and showed that each of the bacterial symbionts is distinct from the others and that all fall within a limited domain of the gamma subdivision of the purple bacteria.
