The complete sequences of isolates of two new bipartite begomoviruses (genus Begomovirus, family Geminiviridae) found infecting weeds in Venezuela are provided. The names proposed for these new begomoviruses are "Datura leaf distortion virus" (DLDV), isolated from a Datura stramonium L. (family Solanaceae) plant, and "Dalechampia chlorotic mosaic virus" (DCMV), isolated from infected Dalechampia sp. (family Euphorbiaceae) and Boerhavia diffusa L. (family Nyctaginaceae) plants. Phylogenetic analysis showed that these new begomoviruses segregated in two distinct clades of New World begomoviruses. To our knowledge, this is the first record of a begomovirus infecting Dalechampia sp. plants. Also, this is the first report of a begomovirus infecting Boerhavia spp. and Datura spp. in Venezuela.
提供了在委内瑞拉感染杂草的两种新二分体伴随病毒（属伴随病毒，家族双生病毒科）分离物的完整序列。为这些新的伴随病毒提议的名称是“颠茄叶扭曲病毒”（DLDV），从颠茄（茄科）植物中分离出来，和“达利坎皮亚花叶病毒”（DCMV），从受感染的达利坎皮亚属（大戟科）和博尔哈维亚扩散（夹竹桃科）植物中分离出来。系统发育分析表明，这些新的伴随病毒在新世界伴随病毒的两个不同分支中分离。据我们所知，这是首例感染达利坎皮亚属植物的伴随病毒的记录。此外，这也是首例在委内瑞拉感染博尔哈维亚属和颠茄属的伴随病毒的报告。
