Technical Abstract: A new tobamovirus species, Hibiscus latent Fort Pierce virus (HLFPV) was recently isolated from the malvaceous plant hibiscus (Hibiscus rosa-sinensis) in the Florida landscape. Virion morphology and genome organization are typical of tobamoviruses. The experimental host range of HLFPV is mostly limited to the Malvaceae, which includes economically important ornamental crops like hibiscus, in addition to fiber and food crops such as cotton, kenaf and okra. Another new tobamovirus species, Hibiscus latent Singapore virus (HLSV), was recently reported infecting hibiscus in Singapore. Sequence comparisons indicate that HLFPV is distinct from but related to HLSV. The coat protein (CP) genes and deduced CPs are 68% and 73% identical, respectively, whereas the movement protein (MP) genes and deduced MPs are 70% and 73% identical, respectively. However, the HLFPV and HLSV CP genes are only 45-53% and 37-47% identical at the nucleotide and amino acid levels, respectively, to all other tobamoviruses and the MP genes are even more dissimilar, suggesting the existence of a malvaceous-infecting subgroup of tobamoviruses.
