The process of gene fusion involves the formation of a single chimeric gene from multiple complete or partial gene sequences. Gene fusion is recognized as an important mechanism by which genes and their protein products can evolve new functions. The presence-absence of gene fusions can also be useful characters for inferring evolutionary relationships between organisms. Here we show that the nuclear genomes of two unrelated single-celled algae, the cryptophyte Guillardia theta and the chlorarach...

The Synurophyceae is one of most important photosynthetic stramenopile algal lineages in freshwater ecosystems. They are characterized by siliceous scales covering the cell or colony surface and possess plastids of red-algal secondary or tertiary endosymbiotic origin. Despite their ecological and evolutionary significance, the relationships amongst extant Synurophyceae are unclear, as is their relationship to most other stramenopiles. Here we report a comparative analysis of plastid genomes sequ...

Summary A lineage of predatory, non-photosynthetic protists related to red algae has been discovered, changing the way we think about the biology of the first photosynthetic eukaryotes.
Cyanobacteria occupy a special place in the pantheon of prokaryotic life. It is in the ancestors of these ubiquitous microbes that oxygenic photosynthesis first evolved more than 2 billion y ago (1), and it is from endosymbiotic cyanobacteria that the plastids (chloroplasts) of plants and algae are derived (2). Modern-day cyanobacteria are diverse in form and function; they include coccoid marine picoplankton such as Prochlorococcus (3), freshwater biofilm-forming genera [e.g., Gloeomargarita (4...

Oomycetes include many well-studied, devastating plant pathogens. Across oomycete diversity, plant-infecting lineages are interspersed by non-pathogenic ones. Unfortunately, our understanding of the evolution of lifestyle switches is hampered by a scarcity of data on the molecular biology of saprotrophic oomycetes, ecologically important primary colonizers of dead tissue that can serve as informative reference points for understanding the evolution of pathogens. Here, we established Salisapilia ...
