Red and green algal monophyly and extensive gene sharing found in a rich repertoire of red algal genes
The Plantae comprising red, green (including land plants), and glaucophyte algae are postulated to have a single common ancestor that is the founding lineage of photosynthetic eukaryotes [1, 2]. However, recent multiprotein phylogenies provide little [3, 4] or no [5, 6] support for this hypothesis....

However, recent multiprotein phylogenies provide little [3, 4] or no [5, 6] support for this hypothesis.

Here, using novel genome data from the mesophilic Porphyridium cruentum and Calliarthron tuberculosum, we analyze 60,000 novel red algal genes to test the monophyly of red + green (RG) algae and their extent of gene sharing with other lineages. Using a gene-by-gene approach, we find an emerging signal of RG monophyly (supported by ∼50% of the examined protein phylogenies) that increases with the number of distinct phyla and terminal taxa in the analysis. A total of 1,808 phylogenies show evidence of gene sharing between Plantae and other lineages.
