Abstract

The complete genome sequence of maracuja mosaic virus (MarMV) was determined and analyzed. The full MarMV genome consisted of 6794 nucleotides, and this is the largest genome size among known tobamoviruses. The MarMV genome RNA contained four open reading frames (ORFs) coding for proteins of M(r) 126, 181, 34 and 18 kDa from the 5′ to 3′ end, respectively. The lengths of the 5′ nontranslated region (NTR) and the 3′ NTR were 54 and 177 nucleotides, respectively. Phylogenetic tree analysis revealed that these MarMV-encoded proteins are related to members of the Malvaceae - and Cucurbitaceae -infecting tobamoviruses. MarMV is different from other tobamoviruses and forms a new Passifloraceae -infecting subgroup. Western blot analysis showed that MarMV cross-reacted strongly with antibodies against Kyuri green mottle mosaic virus and Hibiscus latent Singapore virus. Synthesized capped transcripts from full-length cDNA of MarMV were infectious. These data clearly indicate that MarMV belongs to a separate species of the genus Tobamovirus .
