Begomoviruses are whitefly-transmitted, single-stranded DNA viruses that infect a variety of cultivated (crop) and non-cultivated (weed) plants. The present study identified a novel begomovirus and satellites (alpha- and betasatellite) in Senna occidentalis (syn. Cassia occidentalis) showing leaf curl symptoms. The begomovirus shared a maximum sequence identity of 88.6 % with french bean leaf curl virus (JQ866297), whereas the alphasatellite and the betasatellite shared identities of 98 % and 90 % with ageratum yellow vein India alphasatellite (LK054802) and papaya leaf curl betasatellite (HM143906), respectively. No other begomovirus or satellites were detected in the suspected plants. We propose to name the virus "senna leaf curl virus" (SenLCuV).
双生病毒是由粉虱传播的单链DNA病毒，可感染多种栽培（作物）和非栽培（杂草）植物。本研究在表现出卷叶症状的西番莲（syn. 决明）中鉴定出一种新型双生病毒及卫星核酸（α卫星核酸和β卫星核酸）。该双生病毒与菜豆卷叶病毒（JQ866297）的最大序列同一性为88.6%，而α卫星核酸和β卫星核酸分别与胜红蓟黄脉印度α卫星核酸（LK054802）和番木瓜卷叶β卫星核酸（HM143906）的同一性为98%和90%。在疑似植物中未检测到其他双生病毒或卫星核酸。我们建议将该病毒命名为“番莲卷叶病毒”（SenLCuV）。
