The presence of an inhibitor of tobacco mosaic virus (TMV) infection was demonstrated in extracts of Nicotiana glutinosa infected with the fungus Thielaviopis basicola. The inhibitor was shown to spread systemically in the infected plant. It was found to be heat‐stable, but rapidly lost its activity upon dilution or dialysis. The inhibitor does not act directly on the virus and lacks the power to decrease infectivity of virus already present in the cells.
A similar inhibitor was extracted from the fungal body, differing only slightly from the one extracted from fungus‐infected plant tissue.
