The ecology of Cucumber mosaic virus and sustainable agriculture.
An account is given of the ecology of Cucumber mosaic virus (CMV) as a pertinent example of how a virus can affect the sustainability of an important crop. It is now generally accepted that the technologies used in modern agriculture should ensure that production systems are operated in such a way that the quality of the produce is maintained year after year without causing degradation of the environment. Recent experiences in countries of the Mediterranean basin demonstrate that the benefits expected from the introduction of new and highly productive plant varieties may be quickly eroded by the concomitant introduction of new virus strains which can greatly change the structure of the resident virus population. Quarantine inspection of plant propagules and genetic engineering are suggested as powerful tools to help achieve sustainability.
