The smallest known eukaryotes, at ≈1-μm diameter, are Ostreococcus tauri and related species of marine phytoplankton. The genome of Ostreococcus lucimarinus has been completed and compared with that of O. tauri. This comparison reveals surprising differences across orthologous chromosomes in the two species from highly syntenic chromosomes in most cases to chromosomes with almost no similarity. Species divergence in these phytoplankton is occurring through multiple mechanisms acting differently…

Typical Features of Genomes in the Mamiellophyceae

Prasinophyte algae lie at the base of the green lineage, but various metabolic processes reflect their marine lifestyles and distinguish them from land plants, including a high proportion of selenoprotein enzymes and C4 photosynthesis.

Cryptic sex in the smallest eukaryotic marine green alga.

The complete genomes of three strains from different ecological niches revealed them to represent biologically distinct species despite their identical cellular morphologies (cryptic species), and showed that sexual exchanges must be inferred to account for the between-locus and between-chromosome marker combinations observed.

A Viral Immunity Chromosome in the Marine Picoeukaryote, Ostreococcus tauri

It is shown that virus-producing resistant cell lines arise in many independent cell lines during lytic infections, but over two years, more and more of these lines stop producing viruses.

Comparative Genomics of a Bacterivorous Green Alga Reveals Evolutionary Causalities and Consequences of Phago-Mixotrophic Mode of Nutrition

The results suggest that early, ancestral host eukaryotes that gave rise to phototrophs had the capacity to assimilate building block molecules from inorganic substances (i.e., prototrophy) and may at least partially explain the apparent lack of instances of permanent incorporation of photosynthetic endosymbionts in later-divergent, auxotrophic eukARYotic lineages, such as metazoans and ciliates.

Clues about the genetic basis of adaptation emerge from comparing the proteomes of two Ostreococcus ecotypes (Chlorophyta, Prasinophyceae).

It is shown that faster evolving genes encode significantly more membrane or excreted proteins, consistent with the notion that selection acts on cell surface modifications that is driven by selection for resistance to viruses and grazers, keystone actors of phytoplankton evolution.

Green Evolution and Dynamic Adaptations Revealed by Genomes of the Marine Picoeukaryotes Micromonas

It is found that genomes from two isolates shared only 90% of their predicted genes, and divergence appears to have been facilitated by selection and acquisition processes that actively shape the repertoire of genes that are mutually exclusive between the two isolate differently than the core genes.

The Penium margaritaceum Genome: Hallmarks of the Origins of Land Plants

Genomics against flatulence

The list of recently sequenced genomes includes bacteria that inhabit a variety of ecological niches and degrade numerous environmental contaminants, as well as two γ-proteobacteria with near-minimal gene sets.

Gene functionalities and genome structure in Bathycoccus prasinos reflect cellular specializations at the base of the green lineage

The minimal genomes of the Mamiellophyceae provide a baseline for evolutionary and functional analyses of metabolic processes in green plants and it is hypothesized that these genes are associated with the process of scale biogenesis.

Ancient recruitment by chromists of green algal genes encoding enzymes for carotenoid biosynthesis.

It is argued that the prasinophyte genes were retained because they enhance photosynthetic performance in chromalveolates, thus extending the niches available to these organisms, and found a mosaic evolutionary origin of these enzymes in chromists.



Genome analysis of the smallest free-living eukaryote Ostreococcus tauri unveils many unique features.

The complete genome sequence of an ancient member of this lineage, the unicellular green alga Ostreococcus tauri, is unveiled, making O. tauri an ideal model system for research on eukaryotic genome evolution, including chromosome specialization and green lineage ancestry.

Ecotype diversity in the marine picoeukaryote Ostreococcus (Chlorophyta, Prasinophyceae).

Different growth rates and features strongly suggest distinct adaptation to environmental conditions encountered at surface and the bottom of the oceanic euphotic zone, reminiscent of that described in prokaryotes.

The Genome of the Diatom Thalassiosira Pseudonana: Ecology, Evolution, and Metabolism

It is identified novel genes for silicic acid transport and formation of silica-based cell walls, high-affinity iron uptake, biosynthetic enzymes for several types of polyunsaturated fatty acids, use of a range of nitrogenous compounds, and a complete urea cycle, all attributes that allow diatoms to prosper in aquatic environments.

Mmicular mechanisms of cytochrome c biogenesis: three distinct systems

In this review, common principles of assembly for all systems and the mmicular mechanisms predicted for each system are summarized.

Study of Genetic Diversity of Eukaryotic Picoplankton in Different Oceanic Regions by Small-Subunit rRNA Gene Cloning and Sequencing

The diversity of marine picoeukaryotes was determined by sequencing cloned 18S rRNA genes in five genetic libraries from North Atlantic, Southern Ocean, and Mediterranean Sea surface waters, and the phylogenetic diversity in each library was rather great, and each library included many different OTUs and members of very distantly related phylogenetic groups.

Copper-containing plastocyanin used for electron transport by an oceanic diatom

It is reported that the greater Cu requirement in an oceanic diatom, Thalassiosira oceanica, is entirely due to a single Cu-containing protein, plastocyanin, which was only known to exist in organisms with chlorophyll b and cyanobacteria.

A comprehensive evolutionary classification of proteins encoded in complete eukaryotic genomes

Functional and evolutionary patterns in the recently constructed set of 5,873 clusters of predicted orthologs (eukaryotic orthologous groups or KOGs) from seven eukaryosis genomes are examined, revealing a conserved core of largely essential eukARYotic genes as well as major diversification and innovation associated with evolution of eUKaryotic genomes.

Evolution of selenocysteine-containing proteins: significance of identification and functional characterization of selenoproteins.

It is proposed that Sec was added to the already existing genetic code and its use has accumulated during evolution of eukaryotes culminating in vertebrates.

Abundance and Distribution of Ostreococcus sp. in the San Pedro Channel, California, as Revealed by Quantitative PCR

A genus-specific TaqMan-based quantitative PCR assay is designed and implemented to investigate the dynamics and ecology of Ostreococcus at the USC Microbial Observatory and demonstrates the seasonal dynamics of this genus and its contribution to picoeukaryote biomass at the coastal sampling station.
