Fig. 3: Phylogenetic analyses of the DRB and RDR genes.

a A maximum likelihood tree of DRB in selected Viridiplantae species. b A maximum likelihood tree of RDR in selected Viridiplantae species. Other RDR homologs were taken as an outgroup. The tree was constructed by maximum likelihood using 500 bootstrap replicates, values ≥20% are shown on internal branches. For species designations of sequence IDs see Supplementary data S3.
