Abstract

This is the first description of the complete genome sequence of a new monopartite begomovirus isolated from tomato leaves with symptoms of tomato (yellow) leaf curl disease collected on Reunion Island, for which we propose the name "tomato yellow leaf curl Reunion virus" (TYLCREV). Phylogenetic analysis showed that TYLCREV belongs to the Old World monopartite begomoviruses and is most closely related to tomato yellow leaf curl virus (TYLCV). The genome of TYLCREV displays evidence of interspecies recombination and is composed of a portion (52%) that is closely related to TYLCV (>97.6% sequence identity) and a portion (48%) that is closely related to begomoviruses that have been found in tomato plants in Madagascar (> 91.6% sequence identity). The discovery of TYLCREV in diseased tomato plants in Reunion calls for epidemiological surveillance and further investigations to assess the prevalence and risks associated to this new virus in Reunion and beyond.

留尼旺岛番茄黄卷叶病毒：一种来自留尼旺岛的新型番茄感染单株begomavirus。

这是首次对从留尼汪岛收集的具有番茄（黄）卷叶病症状的番茄叶片中分离到的一种新的单株begomavirus的全基因组序列进行描述，我们建议将其命名为“番茄黄卷叶留尼汪病毒”（TYLCREV）。系统发育分析表明，TYLCREV属东半球单株begomovirus，与番茄黄卷叶病毒（tomato yellow leaf curl virus， TYLCV）亲缘关系最密切。TYLCREV的基因组显示出种间重组的证据，由与TYLCV密切相关的部分（52%）和与马达加斯加番茄植株中发现的begomovirus密切相关的部分（48%）组成（> 91.6%）。在留尼汪岛患病番茄植株中发现TYLCREV，要求开展流行病学监测和进一步调查，以评估留尼汪岛及其他地区这种新病毒的流行情况和相关风险。

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.
