Caulimovirus genome linearised at the pregenomic RNA transcription start site (black arrow), numbered from the Met-tRNA primer binding site (black diamond). ORFs (light grey) include domains for the viral movement protein (VMP, blue), coat protein conserved C-terminus (CP, green), retropepsin (pepsin-like aspartic protease, AP, red), reverse transcriptase (RT, orange), RNase H1 (RH1, yellow), and translation transactivator (TA, black).
