Primary plastids derive from a cyanobacterium that entered into an endosymbioticrelationship with a eukaryotic host. This event gave rise to the supergroup Archaeplastida whichcomprises Viridiplantae (green algae and land plants), Rhodophyta (red algae) and Glaucophyta. Afterprimary endosymbiosis, red and green algae spread the ability to photosynthesize to other eukaryoticlineages via secondary endosymbioses. Although considerable progress has been made in theunderstanding of the evolution of… 

New Material of Carbonaceous Compressions from the ∼1.5 Ga Singhora Group, Chhattisgarh Supergroup, India, and their Interpretation as Benthic Algae

The origin, antiquity, and affinity of benthic seaweeds (multicellular algae) in the geological past are shrouded in mystery due to their preservation bias. In this study, we present a new material

A template for an improved rock-based subdivision of the pre-Cryogenian timescale

The geological timescale before 720 Ma uses rounded absolute ages rather than specific events recorded in rocks to subdivide time. This has led increasingly to mismatches between subdivisions and the

The single, ancient origin of chromist plastids

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.

Primary endosymbiosis: have cyanobacteria and Chlamydiae ever been roommates?

A reevaluation of the contribution of Chlamydiae genes to the genome of Archaeplastida is presented and the strengths and weaknesses of this tripartite model for primary endosymbiosis are discussed.

The many twists and turns of plastid evolution each represent major evolutionary transitions, and each offers a glimpse into how genomes evolve and how cells integrate through gene transfers and protein trafficking.

Algal genomes reveal evolutionary mosaicism and the fate of nucleomorphs

The nuclear genomes of the cryptophyte Guillardia theta and the chlorarachniophyte Bigelowiella natans are sequenced and extensive genetic and biochemical mosaicism is revealed, with both host- and endosymbiont-derived genes servicing the mitochondrion, the host cell cytosol, the plastid and the remnant endosYmbionT cytOSol of both algae.

The Glaucophyta: the blue-green plants in a nutshell

Diverse comparative studies using information from the nuclear genome of Cyanophora paradoxa and recent transcriptomic data from other glaucophyte species provide support for the common origin of Archaeplastida.

A new model for the origin of multimembrane plastids belonging to the red lineage is proposed and it is suggested that obstacles in solving this dilemma result from the acceptance of a single evolutionary scenario for the endosymbiont‐to‐plastid transformation formulated by Cavalier‐Smith & Lee (1985).

Tertiary endosymbiosis driven genome evolution in dinoflagellate algae.

These results underline the remarkable ability of dinoflagellates to remodel their genomes through endosymbiosis and the considerable impact of this process on cell evolution.
