Yellow tailflower mild mottle virus: a new tobamovirus described from Anthocercis littorea (Solanaceae) in Western Australia.

The complete genome sequence of a tobamovirus was determined from a wild plant of yellow tailflower (Anthocercis littorea, family Solanaceae) that exhibited mild mottling and chlorosis on the leaves. The virus induced severe symptoms including systemic necrosis when inoculated to plants of three other solanaceous species. The viral genome was resequenced after passage in Nicotiana benthamiana. The two genomes were 6379 nucleotides in length, and they differed by three nucleotides. Phylogenetic analysis and the deduced architecture of the genome place the virus, provisionally named yellow tailflower mild mottle virus, with other tobamoviruses that infect solanaceous hosts.
