Abstract

UNLABELLED

Summary Taxonomy: Turnip mosaic virus (TuMV) is a member of the genus Potyvirus (type species Potato virus Y) in the family Potyviridae. To date, TuMV is the only potyvirus known to infect brassicas. There are potyvirus isolates that appear serologically similar to TuMV when tested with polyclonal antisera that do not readily infect brassicas (Lesemann and Vetten, 1985). Physical properties: Virions are approximately 720 x 15-20 nm flexuous rods (Fig. 1) and are composed of 95% coat protein (CP) and 5% RNA. Hosts: TuMV has been isolated from a wide range of crop and weed plant species. It is known to infect at least 318 species in over 43 dicot families, including Cruciferae, Compositae, Chenopodiaceae, Leguminosae and Caryophyllaceae and is also known to infect monocots. It has the broadest known host range in terms of plant genera and families of any potyvirus.

TRANSMISSION

Aphid transmitted in the non-persistent manner, by at least 89 species, including Myzus persicae and Brevicoryne brassicae. Useful website: http://www.ncbi.nlm.nih.gov/ICTVdb/ICTVdB/57010072.htm.

分类概要：芜菁花叶病毒（TuMV）是马铃薯 Y 病毒属（Potyvirus）（模式种）在马铃薯 Y 病毒科（Potyviridae）中的一员。迄今为止，TuMV 是唯一已知感染芸薹属植物的马铃薯 Y 病毒属病毒。有一些马铃薯 Y 病毒属的分离株，当用多克隆抗血清进行血清学检测时，与 TuMV 表现出相似性，但不易感染芸薹属植物（Lesemann 和 Vetten，1985）。物理特性：病毒粒子大约为 720 x 15-20nm 的柔韧杆（图 1），由 95%外壳蛋白（CP）和 5%RNA 组成。宿主：TuMV 已从多种作物和杂草植物物种中分离出来。已知至少感染了 43 个双子叶科的 318 个种，包括十字花科、菊科、藜科、豆科和石竹科，也已知感染单子叶植物。就任何马铃薯 Y 病毒属而言，它在植物属和科方面具有最广泛的已知宿主范围。
