Near-complete genome sequence and biological properties of an allexivirus found in Senna rizzinii in Brazil

Senna rizzinii is a flowering shrub found mainly in the northeast region of Brazil. Here, we report the coding-complete genome sequence, particle morphology, mode of transmission, and the indicator host responses of an isolate of the putative allexivirus cassia mild mosaic virus (CaMMV) found in S. rizzinii . The virus was transmitted mechanically to Chenopodium amaranticolor , C. quinoa , Gomphrena globosa , which showed local lesions, and S. rizzinii , and S. occidentalis , which were infected systemically. It was also efficiently transmitted to S. rizzinii by grafting. Seed transmission was not observed. The near-complete genome sequence of the virus is 7829 nucleotides in length, containing six open reading frames (ORF), like other allexiviruses.
