(a) Genomic structure of green Sichuan pepper-enamovirus (GSPEV) and profile distribution of transcriptomic reads from GSPEV. The colorful blocks in proteins represent conserved amino acid sequences, domains or motifs. P0, P1 and P1-P2 are the protein names. Pro: Proteinase. Hel: Helicase. VPg: Viral protein linked to the genome. RdRp: RNA dependent RNA polymerase. APC: APC domain. CP: Coat protein. CP-RTD: CP-RTD fusion protein; (b) phylogenetic tree constructed from amino acid sequences of the RdRp domains within GSPEV (marked with small red triangle) and viruses of the family Luteoviridae, using the maximum-likelihood method with JTT model, 1000 bootstrap replicates, and with the bootstrap percent values >50 shown on the nodes. The accession number associated with a virus is in taxa names.
