Abstract
It has been known for some time that plant viruses are inactivated in vitro by ultraviolet (UV) irradiation (Arthur and Newell, 1929). The studies of Hollaender and Duggar (1936) and Price and Gowen (1937) have shown that tobacco mosaic virus (TMV) is inactivated in vitro according to a simple exponential law suggestive of a "one hit" process. More recently plant viruses have been inactivated in vivo by UV irradiation. Bawden and Kleczkowski (1955) found that the development of virus-induced lesions on French bean leaves could be wholly or partially inhibited by UV irradiation subsequent to inoculation with Rothamsted tobacco necrosis virus. This was interpreted as inactivation of virus in vivo by UV irradiation, and is reportedly affected by several factors: (1) the effects of UV irradiation upon the host cells themselves, (2) the age of infection, and (3) the temperature.
