title: Phylogenetic placement of a novel tenuivirus from the grass Urochloa plantaginea.
abstract: Evidence is presented that a tenuivirus recovered from the grass Urochloa plantaginea is probably a novel tenuivirus species, to be called Urochloa hoja blanca virus (UHBV). It is related to both Echinochloa hoja blanca virus (EHBV) and Rice hoja blanca virus (RHBV), and these three form a group distinct from Maize stripe virus (MStV) and Rice stripe virus (RStV). Phylogenetic analysis of the sequence data for RNA-3 and RNA-4 of these viruses supports the hypothesis that EHBV and UHBV may have evolved from an ancestral form of RHBV, precipitated by the introduction of Echinochloa colona and Urochloa plantaginea to America.
