Fig. 4: Phylogenetic trees of subunit 1 of RNA polymerase.

a A maximum likelihood tree for subunit 1 of RNA polymerase in selected Viridiplantae species. b A maximum likelihood tree of subunit 1 of RNA polymerase using an extended taxon sampling of bryophytes. The domain information is displayed for each group. The tree was constructed by maximum likelihood using 500 bootstrap replicates, values ≥30% are shown on internal branches. The PROTCATGTR model was predicted by Modelfinder. For species designations of sequence IDs, see Supplementary data S3.
