摘要
从尼日利亚埃多州伊瓜万田间自然感染的茄子中分离出一株新型begomavirus，命名为茄子黄花叶病毒（EYMV）。其完整的单分子基因组长2805个核苷酸（nt），包含两个病毒粒子感（V1和V2）和四个互补感（C1-C4）开放阅读框。两两比较，EYMV与番茄卷曲喀麦隆病毒分离株gh - tu -12的基因组序列同源性最高（86%）。系统发育分析表明，EYMV与秋葵黄皱病毒（OYCrV）属于同一进化支。进一步分析发现EYMV具有重组性质，可能的主亲本病毒为OYCrV，次亲本病毒为尼日利亚番茄卷曲叶病毒。建议将EYMV命名为“瓜黄begomvirus”。
Molecular identification of a new monopartite begomovirus isolated from eggplant (Solanum melongena L.) with yellow mosaic symptoms in Nigeria
An isolate of a novel begomovirus, named eggplant yellow mosaic virus (EYMV), was molecularly characterized from a naturally infected, field-collected eggplant exhibiting yellow mosaic symptom in Iguowan, Edo State, Nigeria. Its complete monopartite genome is 2,805 nucleotides (nt) long, containing two virion-sense (V1 and V2) and four complementary-sense (C1–C4) open reading frames. In pairwise comparisons, EYMV shared the highest (86%) genome sequence identity with tomato leaf curl Cameroon virus isolate GH-Tou-12. Phylogenetic analysis showed that EYMV belonged to the same clade as okra yellow crinkle virus (OYCrV). Further analysis revealed the recombinant nature of EYMV, with the potential major and minor parental viruses being OYCrV and tomato leaf curl Nigeria virus, respectively. The species name "Begomovirus melongenaflavi" is proposed for EYMV.
期刊介绍：
Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
