Abstract
High-throughput sequencing was used to analyze Hibiscus rosa-sinensis (family Malvaceae) plants with virus-like symptoms in Hawaii. Bioinformatic and phylogenetic analysis revealed the presence of two tobamoviruses, hibiscus latent Fort Pierce virus (HLFPV) and a new tobamovirus with the proposed name "hibiscus latent Hawaii virus" (HLHV). This is the first report of the complete sequence, genome organization, and phylogenetic characterization of a tobamovirus infecting hibiscus in Hawaii. RT-PCR with virus-specific primers and Sanger sequencing further confirmed the presence of these viruses. Inoculation experiments showed that HLFPV could be mechanically transmitted to Nicotiana benthamiana and N. tabacum, while HLHV could only be mechanically transmitted to N. benthamiana.
