The Marine Microbial Eukaryote Transcriptome Sequencing Project (MMETSP): Illuminating the Functional Diversity of Eukaryotic Life in the Oceans through Transcriptome Sequencing
This Community Page describes a resource of 700 transcriptomes from marine microbial eukaryotes to help understand their role in the world's oceans.
Phylogeny and Molecular Evolution of the Green Algae
Current understanding of organelle genome evolution in the green algae is summarized, genomic insights into the ecology of oceanic picoplanktonic prasinophytes, molecular mechanisms underlying the evolution of complexity in volvocine green algae, and the Evolution of genetic codes and the translational apparatus in green seaweeds are summarized.
Mitochondrial and plastid genome architecture: Reoccurring themes, but significant differences at the extremes
It is argued that organelle DNA repair processes, mutation rates, and population genetic landscapes are all important factors leading to the observed convergence and divergence in organelle genome architecture.

Findings provide convincing support for the earlier proposed theory that the GC content of land-plant organelle DNA is positively correlated and directly connected to levels of organelle RNA editing.
Correlation between Nuclear Plastid DNA Abundance and Plastid Number Supports the Limited Transfer Window Hypothesis
Analysis of newly available genome sequences from diverse mono- and polyplastidic taxa shows that the limited transfer window hypothesis holds, and NUPT content was positively related to nuclear genome size, indicating that in addition to plastid number, NUPTs are influenced by the forces controlling the expansion and contraction of noncoding nuclear DNA.

It is argued that for many protists the plastid mutation rate is lower than that of the mitochondrion, including groups with primary or secondary plastids as well as nonphotosynthetic algae.
Complete Mitochondrial DNA Sequence of the Scallop Placopecten magellanicus: Evidence of Transposition Leading to an Uncharacteristically Large Mitochondrial Genome
Transposition involving tRNAs or tRNA-like structures is occurring and is responsible for the large size and abundance of noncoding DNA in the molecule, suggesting a small, compact organization is an actively maintained feature of metazoan mtDNA.
The GC-Rich Mitochondrial and Plastid Genomes of the Green Alga Coccomyxa Give Insight into the Evolution of Organelle DNA Nucleotide Landscape
This work presents the GC-rich mitochondrial and plastid DNAs from the trebouxiophyte green alga Coccomyxa sp.
