Sumario:A novel RNA virus was identified in firespike (Odontonema tubaeforme) plants exhibiting leaf curling and chlorosis. The molecular features of the viral genomic RNA and proteins resemble those of ampeloviruses. Based on sequence comparisons and phylogenetic analysis, we propose a new species in the genus Ampelovirus, which we have tentatively named Firespike leafroll-associated virus (FLRaV). Bioassays showed that the virus is mechanically transmissible to Nicotiana benthamiana. In addition, a full-length cDNA clone of FLRaV could successfully infect N. benthamiana via agroinfiltration.
