Summary	Three diverse eukaryotic groups are thought to be related by primary endosymbiosis and have been placed together in the Kingdom Plantae: these are the glaucocystophytes, rhodophytes and green plants. Certain physical characteristics of their plastids have indicated that glaucocystophytes could be the ancestor of this group. The purpose of this research is to find evidence that glaucocystophytes are the protistan ancestors of green plants. The sequence of the largest subunit of RNA polymerase II (RPBI) is examined because it is evolutionarily conserved and, therefore, makes a suitable gene for comparative analyses of early eukaryote evolution. Three complementary approaches are used to place Glaucocystophyta on the evolutionary tree; phylogenetic analyses of RPBI sequences, presence of a conserved C-terminal domain, and intron positions in RPBI. Data from all three characters are consistent with a close relationship between green plants and glacucocystophytes, but do not provide compelling support that they are immediate sister groups.
