Table 1. Distribution of red algal plasmids and their homologous sequences (BLASTp results, cut-off = e⁻⁰⁵).

Rd = red algae, Cy = Cyanobacteria, Bc = Bacteria (excluding Cyanobacteria), Gn = green plant lineage (Viridiplantae), Vr = Virus, Rz = Rhizaria, St = Stramenopile. Letters beside the filled circles indicate origins: m for the mitochondrial homolog, p for the plastid homolog and g for the nuclear genome homolog. When the letters m, p, or g are absent, the origin of the gene is unknown.
