Three monocot-infecting mastreviruses from Australia, all found primarily in pasture and naturalised grasses, have been characterised at the molecular level. Here, we present the full genome sequence of a fourth, Paspalum striate mosaic virus (PSMV), isolated from Paspalum dilatatum from south-east Queensland. The genome was 2816 nt long and had an organisation typical of other monocot-infecting mastreviruses. Its nearest relative is Bromus cartharticus striate mosaic virus (BCSMV), with which it shares an overall genome identity of 75%. Phylogenetic analysis of the complete genome and each of the putative viral proteins places PSMV in a group with the other three Australian striate mosaic viruses. PSMV, BCSMV and Digitaria didactyla striate mosaic virus all contain a similar, small recombinant sequence in the small intergenic region.
三种主要感染单子叶植物的玛斯特病毒（mastrevirus）已在分子水平上得到鉴定，它们均来自澳大利亚，主要存在于牧场和归化草中。在此，我们介绍了第四个单子叶植物感染玛斯特病毒，即从昆士兰东南部的帕帕斯草（Paspalum dilatatum）中分离得到的条纹叶斑驳病毒（Paspalum striate mosaic virus，PSMV）的全基因组序列。该基因组长 2816 个核苷酸，具有其他单子叶植物感染玛斯特病毒的典型组织结构。与其亲缘关系最近的是布氏雀麦条纹叶斑驳病毒（Bromus cartharticus striate mosaic virus，BCSMV），两者的全基因组相似度为 75%。基于完整基因组和每个假定病毒蛋白的系统发育分析，PSMV 与其他三种澳大利亚条纹叶斑驳病毒一起构成一个群组。PSMV、BCSMV 和粗山羊草条纹叶斑驳病毒（Digitaria didactyla striate mosaic virus）均在小基因间隔区含有类似的小重组序列。
