摘要

Allexivirus（Alphaflexiviridae）于1970年由Razvjazkina首次描述。从那时起，许多国家都检测到了Allexivirus物种。尽管本属主要感染石蒜科植物，但其他宿主包括蚕豆科、蔷薇科和兰科植物。已确定13种Allexivirus。其中8种感染葱宿主，包括：小葱病毒X（ShVX）、大蒜病毒A（GarV-A）、大蒜V B（GarV-B）、大蒜C（GarV-C）、大蒜D（GarV-D）、大蒜E（GarV-E）、大蒜X（GarV-X）和大蒜螨丝状病毒（GarMbFV）。已有五种来自非葱属宿主的病毒，包括黑莓病毒E（BVE）、香草潜伏病毒（VLV）、苜蓿病毒S（AVS）、花生毒（ApV）和塞纳严重黄色花叶病毒（SSYMV）。本文分析了13个已识别物种和4个未分配物种（Allexivirus DS-2013/CZE分离株、小葱螨传潜伏病毒（SMbLV）、决明子温和花叶病毒（CaMMV）和木瓜病毒A（PaVA））的分类位置。根据对数据的检查，我们得出结论，PaVA是一种Allexivirus，DS-2013/CZE是GarV-D的分离株，SMbLV是ShVX的分离株。还总结了目前对这些病毒的宿主范围、症状、基因组结构和传播模式的了解，并概述了针对它们采取的控制措施。

Allexivirus: review and perspectives

Allexivirus (Alphaflexiviridae) was first described in 1970 by Razvjazkina. Since then, Allexivirus species have been detected in many countries. Although this genus primarily infects plants in the Amaryllidaceae, other hosts include plants in the Fabaceae, Rosaceae and Orchidaceae. Thirteen Allexivirus species have been assigned. Eight of these infect Allium hosts, and these include: shallot virus X (ShVX), garlic virus A (GarV-A), garlic virus B (GarV-B), garlic virus C (GarV-C), garlic virus D (GarV-D), garlic virus E (GarV-E), garlic virus X (GarV-X), and garlic-mite filamentous virus (GarMbFV). Five have been described from non-Allium hosts, including blackberry virus E (BVE), vanilla latent virus (VLV), alfalfa virus S (AVS), Arachis pintoi virus (ApV), and Senna severe yellow mosaic virus (SSYMV). This review analyzes the taxonomic positions of the thirteen recognized species and four unassigned species (Allexivirus DS-2013/CZE isolate, shallot mite-borne latent virus (SMbLV), cassia mild mosaic virus (CaMMV), and papaya virus A (PaVA)). Based on the inspection of data, we have concluded that PaVA is an Allexivirus, DS-2013/CZE is an isolate of GarV-D, and SMbLV is an isolate of ShVX. Current knowledge of the host ranges, symptoms, genome structure and modes of transmission of these viruses is also summarized, and control measures employed against them are outlined.

期刊介绍： Phytopathologia Mediterranea is an international journal edited by the Mediterranean Phytopathological Union. The journal’s mission is the promotion of plant health for Mediterranean crops, climate and regions, safe food production, and the transfer of new knowledge on plant diseases and their sustainable management. The journal deals with all areas of plant pathology, including etiology, epidemiology, disease control, biochemical and physiological aspects, and utilization of molecular technologies. All types of plant pathogens are covered, including fungi, oomycetes, nematodes, protozoa, bacteria, phytoplasmas, viruses, and viroids. The journal also gives a special attention to research on mycotoxins, biological and integrated management of plant diseases, and the use of natural substances in disease and weed control. The journal focuses on pathology of Mediterranean crops grown throughout the world. The Editorial Board of Phytopathologia Mediterranea has recently been reorganised, under two Editors-in-Chief and with an increased number of editors.
