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.

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.
Phylogenomic analysis supports the monophyly of cryptophytes and haptophytes and the association of rhizaria with chromalveolates.

It is postulated that the plastid of peridinin- and fucoxanthin-containing dinoflagellates originated from a haptophyte tertiary endosymbiosis that occurred before the split of these lineages.
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.
Insights into a dinoflagellate genome through expressed sequence tag analysis
This is the most extensive collection to date of ESTs from a toxic dinoflagellate and will be instrumental to future research to understand the unique and complex cell biology of these organisms and for potentially identifying the genes involved in toxin production.
Photosynthetic eukaryotes unite: endosymbiosis connects the dots.

Algal diversity is examined and endosymbiosis is shown to be a major force in algal evolution, with long-standing issues such as the chromalveolate hypothesis and the extent of endOSymbiotic gene transfer clarified.
The Single, Ancient Origin of Chromist Plastids
Here a taxonomically diverse group of chlorophyll are analyzed to show that a taxonomicically diversegroup ofchlorophyll is represented in algal lineages with complex evolutionary history involving a secondary en-dosymbiotic event.

A taxonomically diverse group of chlorophyll c2-containing protists comprising cryptophyte, haptophyte and stramenopiles algae (Chromista) share a common plastid that most likely arose from a single, ancient secondary endosymbiosis involving a red alga, consistent with Chromista monophyly and implicates secondary endOSymbiotic as an important force in generating eukaryotic biodiversity.
Phylogeny of Alariaceae, Laminariaceae, and Lessoniaceae (Phaeophyceae) based on plastid-encoded RuBisCo spacer and nuclear-encoded ITS sequence comparisons.

The phylogenetic analyses show that the kelps form eight well-supported clades (represented by Egregia, Laminaria, Hedophyllum, Macrocystis, Alaria, Agarum, Ecklonia, and Lessonia) that conform to the tribes of the current morphological classification system of the "advanced"kelps.
