Abstract
A novel RNA virus was identified in firespike () plants exhibiting leaf curling and chlorosis. The molecular features of the viral genomic RNA and proteins resemble those of ampeloviruses. Based on sequence comparisons and phylogenetic analysis, we propose a new species in the genus , which we have tentatively named Firespike leafroll-associated virus (FLRaV). Bioassays showed that the virus is mechanically transmissible to . In addition, a full-length cDNA clone of FLRaV could successfully infect via agroinfiltration.
摘要
一种新型 RNA 病毒在表现出叶片卷曲和黄化的火棘（）植物中被鉴定出来。该病毒基因组 RNA 和蛋白的分子特征与曲叶病毒科病毒相似。基于序列比较和系统发育分析，我们提出了一个新种，暂定名为火棘卷叶伴随病毒（FLRaV）。生物测定表明，该病毒可以通过机械接种传播给。此外，FLRaV 的全长 cDNA 克隆可以通过农杆菌浸润成功感染。
