Two begomoviruses were isolated in the northern Brazilian state of Pará, infecting non-cultivated Hibiscus sp. and cultivated tomato (Solanum lycopersicum). The complete genomes (DNA-A and DNA-B) of the two viruses showed the typical organization of New World bipartite begomoviruses. Based on the species assignment criteria in the genus Begomovirus, each virus is a member of a new species. The virus from Hibiscus is most closely related to sida yellow mosaic Yucatan virus, while the tomato virus is most closely related to abutilon mosaic Brazil virus and corchorus mottle virus. Recombination events were detected in the DNA-A of the tomato virus, but not in the Hibiscus virus genome. We propose the names "hibiscus golden mosaic virus" (HGMV) and "tomato chlorotic leaf curl virus" (ToCLCV) for the viruses reported in this study.
在巴西北部的帕拉州分离出两种双生病毒，它们分别感染野生的木槿属植物和栽培番茄（茄属番茄）。这两种病毒的完整基因组（DNA-A和DNA-B）呈现出新大陆双分体双生病毒的典型结构。根据双生病毒属的物种分类标准，每种病毒都是一个新物种的成员。来自木槿的病毒与尤卡坦 sida 黄花叶病毒关系最为密切，而番茄病毒与巴西苘麻花叶病毒和黄麻斑驳病毒关系最为密切。在番茄病毒的DNA-A中检测到了重组事件，但在木槿病毒基因组中未检测到。我们为该研究中报道的病毒分别提议命名为“木槿金色花叶病毒”（HGMV）和“番茄褪绿卷叶病毒”（ToCLCV）。
