title: A novel sugarcane-infecting mastrevirus from South Africa.
abstract: The sugarcane-infecting streak viruses (SISVs) are a diverse collection of mastreviruses (family Geminiviridae) within the African streak virus group. Four SISVs have currently been described, including the well-characterized maize streak virus. Here, we present a full annotated sequence record of an isolate of a new SISV species, Saccharum streak virus (SacSV), isolated in South Africa. The isolate shares less than 66% identity with any other mastrevirus, but is most closely related to Urochloa streak virus (USV), a mastrevirus from Nigeria that has until now been an outlier in the African streak virus phylogenetic tree. As with USV, the SacSV isolate we have characterized bears no obvious evidence of inter-species recombination.
