Abstract
CUCUMBER mosaic viruses 3 and 4 of Ainsworth1 have many properties in common with tobacco mosaic virus, in spite of the fact that they do not cause disease when inoculated to tobacco plants. They are sufficiently stable so that their virus proteins have been isolated chemically2 ; these proteins resemble the tobacco mosaic virus protein in optical characteristics when in solution, in high inactivation temperatures, in the X-ray diffraction patterns3 they produce, and in serological reactions. We have carried through ultracentrifugal isolations of the cucumber virus proteins and have found that they are also like tobacco mosaic virus protein in sedimentation rates.
