Three full-length monopartite begomovirus sequences were obtained from two field-collected pepper plants exhibiting severe leaf yellowing disease symptoms in Yunnan province of China. The three full-length viral sequences contain 2,748 nucleotides (nt) and share the highest nt sequence similarity (88.2% identity) with that of malvastrum yellow vein Yunnan virus (MYVYNV). The betasatellite molecules of the two viruses share the highest sequence similarity (99.3% identity) with that of malvastrum yellow vein Yunnan betasatellite (MYVYNB). Based on the current species demarcation criteria for the genus Begomovirus, these three newly identified isolates can be considered members of a novel monopartite Begomovirus species, and we have named this virus "pepper yellow leaf curl virus" (PepYLCV). Phylogenetic analysis showed that PepYLCV clustered with pepper leaf curl Yunnan virus (PepLCYNV). Recombination analysis revealed that PepYLCV is likely to have originated through a recombination event between MYVYNV and tomato leaf curl Yunnan virus (TLCYnV).
从中国云南省表现出严重叶片黄化病症状的两种田间采集的辣椒植物中获得了三个全长单分体伴生病毒序列。这三个全长病毒序列包含 2748 个核苷酸（nt），与马尔瓦斯特黄脉云南病毒（MYVYNV）的 nt 序列具有最高的相似性（88.2%同一性）。这两种病毒的β卫星分子与马尔瓦斯特黄脉云南β卫星（MYVYNB）具有最高的序列相似性（99.3%同一性）。基于 Begomovirus 属的现行种划分标准，这三个新鉴定的分离物可被视为一种新型单分体 Begomovirus 种的成员，我们将该病毒命名为“辣椒黄卷叶病毒”（PepYLCV）。系统发育分析表明，PepYLCV 与辣椒卷叶云南病毒（PepLCYNV）聚类在一起。重组分析表明，PepYLCV 可能是通过 MYVYNV 和番茄卷叶云南病毒（TLCYnV）之间的重组事件产生的。
