Several species in the genus Datura (family Solanaceae) are hosts for begomoviruses (family Geminiviridae), both in the New World and the Old World. Here, we report the genome characterization of two isolates of a novel Old World monopartite begomovirus infecting Datura innoxia in Sudan, which we propose to be named "datura leaf curl virus" (DaLCV). Pairwise sequence comparisons and phylogenetic analysis showed that DaLCV isolates are related to begomoviruses causing tomato yellow leaf curl disease, a global menace for tomato crops. Thus, the novel begomovirus could pose an additional threat to tomato cultivation in Africa.
曼陀罗属（茄科）的几个物种是新世界和旧世界中双生病毒科（Geminiviridae）菜豆金色花叶病毒属病毒的寄主。在此，我们报告了在苏丹感染无刺曼陀罗的一种新型旧世界单组分双生病毒的两个分离株的基因组特征，我们提议将其命名为“曼陀罗叶卷曲病毒”（DaLCV）。成对序列比较和系统发育分析表明，DaLCV分离株与引起番茄黄化曲叶病的双生病毒有关，番茄黄化曲叶病是番茄作物面临的全球威胁。因此，这种新型双生病毒可能会对非洲的番茄种植构成额外威胁。
