Molecular characterisation of a novel recombinant Ribgrass mosaic virus strain FSHS.

ABSTRACT:

Background

The genus Tobamovirus (Virgaviridae) comprises 33 accepted species with the recent addition of eight new viruses and is divided in to three subgroups based on the origin of assembly of the virion and host range. Within the subgroup 1 tobamoviruses the orchid-associated tobamovirus was hypothesized to be a chimeric derivative of recombinations between genome fragments from subgroup 3 and 1. Recombination events involving RdRp, movement and coat protein genes are recorded within subgroup 1 and 2. However natural recombinations have not previously been reported between subgroup 3 tobamoviruses.

Findings

The organization and phylogenetic analyses of the complete genome and the different ORFs placed the new isolate within the Ribgrass mosaic virus clade of subgroup 3 t
