Liquid Crystalline Preparations of Cucumber Viruses 3 and 4

Abstract

IN a previous note1, we showed that liquid crystalline substances infective at high dilutions could be isolated from solanaceous plants infected with three different strains of tobacco mosaic virus. We have been unable to transmit these strains to cucumber plants, and other workers have found cucumber to be immune to tobacco mosaic virus. From cucumber plants infected with cucumber viruses 3 and 42, we have now isolated nucleoproteins with a similar chemical composition and similar in many of their properties to those obtained from solanaceous plants infected with tobacco mosaic virus ; they are, however, rather less stable and more difficult to isolate.
