Abstract
The inhibitory effect of mucin on infection with purified TMV in a mixture of the 2 components in the proportion of 1 : 1 attains 76.8% . Mucin solution mixed with infective juice from tobacco in the proportion of 1 : 1 reduces the infectivity by only 20-35%. Urinary mucoprotein mixed with infective juice in the proportion of 1 : 1 reduces infectivity by 78.7%. Infection with purified TMV is inhibited by it by almost 100%. The infectivity of the mixture of purified TMV, fresh juice from healthy tobacco plants, and mucoproteins depends on the order in which the components are added together. Mucoprotein combines with TMV and also with an undefined substance from fresh tobacco plants.
