An ancient (late Paleoproterozoic) origin of photosynthetic eukaryotes with the primary endosymbiosis that gave rise to the first alga having occurred after the split of the Plantae from the opisthokonts sometime before 1,558 MYA is supported.
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 natural history of group I introns.
DEFINING THE MAJOR LINEAGES OF RED ALGAE (RHODOPHYTA) 1
This study determined 48 sequences of the PSI P700 chl a apoprotein A1 (psaA) and rbcL coding regions and established a robust red algal phylogeny to identify the major clades and proposes that the Rhodophyta contains two new subphyla, the Cyanidiophytina with a single class, the cyanidiophyceae, and the Rhodology with six classes.
Draft Assembly of the Symbiodinium minutum Nuclear Genome Reveals Dinoflagellate Gene Structure
The origin and establishment of the plastid in algae and plants.
Recent genomic and phylogenomic approaches have significantly clarified plastid genome evolution, the movement of endosymbiont genes to the "host" nuclear genome (endosYmbiotic gene transfer), and plastsid spread throughout the eukaryotic tree of life.

Using a genome-wide approach to estimate the “green” contribution to diatoms, it is identified >1700 green gene transfers, constituting 16% of the diatom nuclear coding potential.
Phylogenomic analysis supports the monophyly of cryptophytes and haptophytes and the association of rhizaria with chromalveolates.

This chapter reviews the current knowledge of gene regulation and transcription in dinoflagellates with regard to the unique aspects of the nuclear genome and the implications for understanding organellar genome evolution are discussed.
Hidden biodiversity of the extremophilic Cyanidiales red algae
The research revealed an unexpected level of genetic diversity among Cyanidiales that revises current thinking about the phylogeny and biodiversity of this group and predicts that future environmental PCR studies will significantly augment known biodiversity that is discovered and demonstrate the Cyanidials to be a species‐rich branch of red algal evolution.
