Whitefly-transmitted RNA viruses that affect intensive vegetable production
Annals of Applied Biology 165 (2), 155-171
Abstract: Intensive vegetable production is constantly facing the emergence of new viral diseases. Apart from the intrinsic features of viruses as plant pathogens, the highly dynamic turnover of cultivars and cultural practices, and the global trade of seeds and products characteristic of intensive vegetable production may favour the emergence of new viruses, as well as the expansion of the geographical range of vectors responsible for their dissemination. Indeed, the efficient transmission of viruses plays a major role in the impact and outcome of viral epidemics. Whiteflies (Hemiptera: Aleyrodidae) that belong to the genera Bemisia and Trialeurodes are efficient virus vectors. Whiteflies transmit viruses of at least four genera, one of DNA viruses, the genus Begomovirus, and three of RNA viruses, Crinivirus, Ipomovirus and Torradovirus. Begomoviruses have been the subject of recent reviews. In this article we review the genome structure, epidemiology and control of whitefly-transmitted RNA viruses that belong to the genera Crinivirus, Ipomovirus and Torradovirus, with an extended discussion on the particular viruses within these genera that are currently causing important outbreaks, such are Cucumber vein yellowing virus (CVYV), Cucurbit yellow stunting disorder virus (CYSDV), Tomato chlorosis virus (ToCV) and Tomato torrado virus (ToTV).
