Codiaeum variegatum (common name, garden croton) is an ornamental plant grown for its bright yellow variegated leaf morphology. Two C. variegatum plants with upward leaf curling and vein swelling symptoms were collected in Faisalabad, Pakistan. Sequencing of clones obtained by PCR amplification with specific primers showed one plant infected with the monopartite begomoviruses pedilanthus leaf curl virus (PeLCV) and papaya leaf curl virus (PaLCuV) and the other to be infected with only PeLCV. Both plants also harboured a betasatellite that was distinct from all previously identified betasatellites, for which the name “codiaeum leaf curl betasatellite” (CoLCuB) is proposed. This is the first identification of a begomovirus and an associated betasatellite infecting C. variegatum in Pakistan. Both PeLCV and PaLCuV cause problems in a number of crop plants, and C. variegatum may act as a reservoir for these agriculturally important viruses. The precise impact and geographical distribution of the newly identified CoLCuB will be investigated.

Codiaeum variegatum（俗称巴豆花园）是一种观赏植物，因其明亮的黄色杂色叶片形态而生长。在巴基斯坦的费萨拉巴德收集了两种具有向上的卷叶和静脉肿胀症状的杂色梭菌。用特异性引物通过PCR扩增获得的克隆的测序显示，一株植物感染了单倍体begomoviruses pedilanthus叶卷曲病毒（PeLCV）和木瓜叶卷曲病毒（PaLCuV），而另一株仅感染了PeLCV。两种植物还都具有一个β卫星，该β卫星不同于以前鉴定的所有β卫星，为此提出了名称“ co叶卷曲β卫星”（CoLCuB）。这是首次感染了变种梭状芽胞杆菌的贝莫病毒和相关的β卫星。在巴基斯坦。PeLCV和PaLCuV都会在许多农作物中引起问题，而杂色梭菌可能充当这些农业重要病毒的贮藏库。将对新确定的CoLCuB的确切影响和地理分布进行调查。
