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.
甘蔗坏死条纹病毒(SISVs)是一个多样化的群体,包含了在非洲坏死条纹病毒组内的类麦二叉蚜病毒(家族 Geminiviridae)。目前已经描述了四个 SISVs,其中包括特征明确的玉米坏死条纹病毒。在这里,我们呈现了一个新的 SISV 种,甘蔗坏死条纹病毒(SacSV)的完整注释序列记录,该病毒分离自南非。该分离株与任何其他类麦二叉蚜病毒的相似度均低于 66%,但与尼日利亚的 Urochloa 坏死条纹病毒(USV)最为接近,后者直到现在一直是非洲坏死条纹病毒系统发育树上的一个异类。与 USV 一样,我们所描述的 SacSV 分离株没有明显的种间重组证据。
