Presence of passiflora latent virus and a serologically distinct strain of maracuja mosaic virus in Passiflora spp. in Florida

Rigid rod-shaped particles with a main maximum length at 312 nm were seen in negatively stained leaf extracts of virus-infected Passiflora incarnata plants growing in Dade County, Florida. The particles were from the tobamovirus, maracuja mosaic virus (MrMV). This isolate (MrMV-FL) induced systemic symptoms in manually inoculated plants of Nicotiana benthamiana, Passiflora edulis f. edulis, P. edulis f. flavicarpa, P. foetida, P. incarnata, and P. quadrangularis (.)
