Two novel mastreviruses (genus Mastrevirus; family Geminiviridae), with proposed names chickpea chlorosis virus (CpCV) and chickpea redleaf virus, are described from chickpea (Cicer arietinum) from eastern Australia. The viruses have genomes of 2,582 and 2,605 nucleotides, respectively, and share similar features and organisation with typical dicot-infecting mastreviruses. Two distinct strains of CpCV were suggested by phylogenetic analysis. Additionally, a partial mastrevirus Rep sequence from turnip weed (Rapistrum rugosum) indicated the presence of a distinct strain of Tobacco yellow dwarf virus (TYDV). In phylogenetic analyses, isolates of Bean yellow dwarf virus, Chickpea chlorotic dwarf Pakistan virus and Chickpea chlorotic dwarf Sudan virus from southern and northern Africa and south-central and western Asia clustered separately from these three viruses from Australia. An Australian, eastern Asian, or south-eastern Asian origin for the novel mastreviruses and TYDV is discussed.
两种新型的牧病毒（属牧病毒；双生病毒科），分别命名为鹰嘴豆黄化病毒（CpCV）和鹰嘴豆红叶病毒，从澳大利亚东部的鹰嘴豆（鹰嘴豆）中分离得到。这两种病毒的基因组分别为 2582 和 2605 个核苷酸，与典型的双子叶植物感染牧病毒具有相似的特征和组织。系统发育分析表明 CpCV 有两种不同的株系。此外，从野萝卜（ Rapistrum rugosum ）中分离到的牧病毒 Rep 序列的一部分表明，存在烟草黄矮病毒（TYDV）的一个独特株系。在系统发育分析中，来自非洲南部和北部以及亚洲中南部和西部的豇豆花叶病毒、鹰嘴豆矮化皱缩巴基斯坦病毒和鹰嘴豆矮化皱缩苏丹病毒的分离物与来自澳大利亚的这三种病毒分开聚类。讨论了新型牧病毒和 TYDV 的澳大利亚、东亚或东南亚起源。
