RNA polymerase subunit 1 (RNAP1) phylogenetic tree. RNAP1 Maximum-Likelihood (ML) tree was constructed using aligned sequences from Megavirales (red), Bacteria (green), Archaea (pink), and Eukarya (blue). The confidence values were computed through SH-like support using the FastTree program. The scale bar represents the number of estimated changes per position.
