A molecular timeline for the origin of photosynthetic eukaryotes.
The appearance of photosynthetic eukaryotes (algae and plants) dramatically altered the Earth's ecosystem, making possible all vertebrate life on land, including humans. Dating algal origin is,… Expand

DEFINING THE MAJOR LINEAGES OF RED ALGAE (RHODOPHYTA) 1
Previous phylogenetic studies of the Rhodophyta have provided a framework for understanding red algal phylogeny, but there still exists the need for a comprehensive analysis using a broad sampling of… Expand

The origin and establishment of the plastid in algae and plants.
The establishment of the photosynthetic organelle (plastid) in eukaryotes and the diversification of algae and plants were landmark evolutionary events because these taxa form the base of the food… Expand

Genomic Footprints of a Cryptic Plastid Endosymbiosis in Diatoms
Green for Diatoms Diatoms account for 20% of global carbon fixation and, together with other chromalveolates (e.g., dinoflagellates and coccolithophorids), represent many thousands of eukaryote taxa… Expand

Draft Assembly of the Symbiodinium minutum Nuclear Genome Reveals Dinoflagellate Gene Structure
BACKGROUND Dinoflagellates are known for their capacity to form harmful blooms (e.g., "red tides") and as symbiotic, photosynthetic partners for corals. These unicellular eukaryotes have permanently… Expand

The natural history of group I introns.
There are four major classes of introns: self-splicing group I and group II introns, tRNA and/or archaeal introns and spliceosomal introns in nuclear pre-mRNA. Group I introns are widely distributed… Expand

Phylogenomic analysis supports the monophyly of cryptophytes and haptophytes and the association of rhizaria with chromalveolates.
Here we use phylogenomics with expressed sequence tag (EST) data from the ecologically important coccolithophore-forming alga Emiliania huxleyi and the plastid-lacking cryptophyte Goniomonas cf.… Expand

A single origin of the peridinin- and fucoxanthin-containing plastids in dinoflagellates through tertiary endosymbiosis
The most widely distributed dinoflagellate plastid contains chlorophyll c2 and peridinin as the major carotenoid. A second plastid type, found in taxa such as Karlodinium micrum and Karenia spp.,… Expand

Photosynthetic eukaryotes unite: endosymbiosis connects the dots.
The photosynthetic organelle of algae and plants (the plastid) traces its origin to a primary endosymbiotic event in which a previously non-photosynthetic protist engulfed and enslaved a… Expand

Insights into a dinoflagellate genome through expressed sequence tag analysis
BackgroundDinoflagellates are important marine primary producers and grazers and cause toxic "red tides". These taxa are characterized by many unique features such as immense genomes, the absence of… Expand
