- Abstract
- Potyvirids (the family Potyviridae) are the largest family of plant RNA viruses. Two novel potyvirid viruses, Striga-associated poty-like virus 1 (SaPlV1) and Striga-associated poty-like virus 2 (SaPlV2), were identified from the transcriptome data of purple witchweed (Striga hermonthica). SaPlV1 was most closely related to bellflower veinal mottle virus (BVMoV), the only member of the genus Bevemovirus, and then to macluraviruses (the genus Macluravirus). The SaPlV1 genome encodes a 2462-amino acid (aa) polyprotein that may be cleaved into nine mature peptides. The cleavage sites of SaPlV1, BVMoV, and macluravirus polyproteins shared strong sequence similarities. SaPlV2 was most closely related to celery latent virus, the sole species of the genus Celavirus, which is the most divergent potyvirid genus. The SaPlV2 polyprotein contained 3329 aa and it may be cleaved into at least seven or eight mature peptides. Phylogenetic analysis suggested that SaPlV1 and SaPlV2 may be novel species of the genera Bevemovirus and Celavirus, respectively. The genome sequences of SaPlV1 and SaPlV2 are useful resources for studying the genome evolution of potyvirids.
