Abstract
SOME of the many previous reports of an in vitro increase in virus or of infectivity of plant viruses have been reviewed1,2, but the phenomenon is not generally accepted3. I believe that the work reported here with cucumber mosaic virus (CMV) in beet is simpler, gives a greater increase and will be more easily confirmed than previous reports. The results are interpreted as caused by slow inactivation of inhibitors of infection, not by an actual increase in virus.
