Red Algal Phylogenomics Provides a Robust Framework for Inferring Evolution of Key Metabolic Pathways

This analysis revealed losses of the mevalonate pathway on at least three separate occasions in lineages that contain Cyanidioschyzon, Porphyridium, and Chondrus, establishing a framework for in-depth studies of the origin and evolution of genes and metabolic pathways in Rhodophyta.

Evidence of ancient genome reduction in red algae (Rhodophyta)

Analysis of orthologous gene gains and losses identifies two putative major phases of genome reduction: in the stem lineage leading to all red algae resulting in the loss of major functions such as flagellae and basal bodies, the glycosyl‐phosphatidylinositol anchor biosynthesis pathway, and the autophagy regulation pathway.

Non-random sharing of Plantae genes

It turns out that genes involved in complex interactive networks such as biological regulation and transcription/translation are less susceptible to endosymbiotic or horizontal gene transfer, when compared to genes with metabolic and transporter functions.

Highly Conserved Mitochondrial Genomes among Multicellular Red Algae of the Florideophyceae

Red algal phylogenetic relationships are elucidated and organelle data support a rapid radiation and surprisingly high conservation of mtDNA gene syntheny among the morphologically divergent multicellular lineages of Rhodymeniophycidae.

Analysis of the Genome of Cyanophora paradoxa : An Algal Model for Understanding Primary Endosymbiosis

Key insights about Plantae evolution that were gleaned from a recent analysis of a draft genome assembly from Cyanophora paradoxa (Glaucophyta) are reviewed and results that conclusively demonstrate Plantae monophyly are presented.

Cyanophora paradoxa Genome Elucidates Origin of Photosynthesis in Algae and Plants

Draft genome and transcriptome data from the basally diverging alga Cyanophora paradoxa are analyzed and provide evidence for a single origin of the primary plastid in the eukaryote supergroup Plantae.

Algal endosymbionts as vectors of horizontal gene transfer in photosynthetic eukaryotes

The idea that Plantae (in particular red algae) are one of the major players in eukaryote genome evolution by virtue of their ability to act as "sinks" and "sources" of foreign genes through HGT and endosymbiosis, respectively is discussed.

Re-evaluating the Green versus Red Signal in Eukaryotes with Secondary Plastid of Red Algal Origin

The impact of EGT on eukaryote genomes is evaluated by reanalyzing the recently published EST dataset for Chromera velia, an interesting test case of a photosynthetic alga closely related to apicomplexan parasites, which reveals the lack of congruence and the subjectivity resulting from independent phylogenomic screens for EGT.

Analysis of horizontal genetic transfer in red algae in the post-genomics age

The impacts of this infusion of red algal genome data on addressing questions regarding the complex nature of algal evolution are explored and the need for scalable phylogenomic approaches to handle the forthcoming deluge of sequence information is highlighted.

Ancient gene paralogy may mislead inference of plastid phylogeny.

Compared and contrasted features associated with genome reduction due to primary endosymbiosis in Paulinella plastids and in marine, free-living strains of the picocyanobacterium, Prochlorococcus to show gene inactivation, concerted evolution, and contraction of gene families that impact highly conserved single-copy phylogenetic markers in the plastid.

A phylogenomic falsification of the chromalveolate hypothesis that estimates signal strength across the three genomic compartments is devised, and the hypothesis is rejected as falsified in favor of more complex evolutionary scenarios involving multiple higher order eukaryotes-eukaryote endosymbioses.

Ancient recruitment by chromists of green algal genes encoding enzymes for carotenoid biosynthesis.

It is argued that the prasinophyte genes were retained because they enhance photosynthetic performance in chromalveolates, thus extending the niches available to these organisms, and found a mosaic evolutionary origin of these enzymes in chromists.

Did an ancient chlamydial endosymbiosis facilitate the establishment of primary plastids?

These findings provide a glimpse into the complex interactions that were necessary to establish the primary endosymbiotic relationship between plastid and host cytoplasms, and thereby explain the rarity with which long-term successful endosYmbiotic relationships between heterotrophs and photoautotrophic relationships were established.
