Assembling the Green Algal Tree of Life (GrAToL).

Green plants, including the green algae and land plants, comprise one of the most diverse groups of eukaryotes. More than 14,000 species of green algae have been described. The green algae are an ancient group originating hundreds of millions of years before the invasion of land by plants. Although we have some ideas about the evolutionary history of land plants and green algae, many of the oldest relationships remain unresolved. For example, the sister taxon to land plants remains controversial, as does the relationship among the major lineages of Chlorophyta (the Chlorophyceae, Trebouxiophyceae and Ulvophyceae). Considering the large number of poorly studied, early-diverging lineages of green algae, a broader phylogenetic framework for understanding their evolutionary history is needed. The Green Algal Tree of Life (GrAToL) is a collaborative project focused on resolving the oldest evolutionary relationships among green algae. The project investigates a large number of taxa from all major groups of green plants, as well as representatives of land plants. Increasingly we are using Next Generation sequencing technology to collect organellar genome data as well as transcriptomic data from select taxa. We will provide an overview of the project as well as a summary of our progress to date.
