Turnip mosaic virus, a virus for all seasons

Abstract Turnip mosaic virus (TuMV) is an economically important virus infecting a broad range of arable and vegetable crops and many wild plant species. It is also of particular scientific interest as it has the broadest host range of any of the potyviruses, infects dicotyledonous and monocotyledonous plants, is transmitted by many (>89) aphid species and is the best adapted potyvirus to Arabidopsis thaliana . For these reasons it has been particularly well studied from many angles and is being exploited for biotechnological purposes. This review aims to consolidate the most recent advances in research on TuMV and will form the basis of an updated version on the Association of Applied Biologists (AAB) Description of Plant Viruses for TuMV.
