Phylogenomic Analysis of Deep-Branching Telonemid.

ABSTRACT: The evolutionary history of eukaryotic supergroups has been investigated primarily by large-scale phylogenomics, but one major hindrance to continued progress is that some major eukaryotic groups have extremely sparse sampling. The phylum Telonemia is one such group. Environmental sampling shows two major subgroups of Telonemia, but there are only multigene phylogenomic data from three closely related species belonging to one of the subgroups, TEL1. Here, a single cell was isolated from the pelagic Pacific Ocean, which SSU phylogenetic analysis reveals to be a telonemid of the TEL2 subgroup and distantly related to telonemids with multigene sequence data. Through single-cell transcriptome sequencing and phylogenomic analysis, we investigate the impact of this new telonemid on the relation
