Spatial organizationofwild-type (strainU1) tobaccomosaicvirus (TMV) and of the temperature-sensitive TMV ts21–66mutant was compared by tritium planigraphy. The ts21–66mutant contains two substitutions in the coat protein(Ile21fiThr and Asp66fiGly) and, in contrast withU1,induces a hypersensitive response (formation of necroses)on the leaves of plants bearing a host resistance geneN¢(forexample Nicotiana sylvestris); TMV U1 induces systemicinfection (mosaic) on the leaves of such plants. Tritium dis-tribution along the coat protein (CP) polypeptide chain wasdetermined after labelling of bothisolated CP preparationsand intact virions. ...
