Abstrakt:	Mutant ts21-66 of the tobacco mosaic virus (TMV) differs from the wild-type TMV-U1 by two mutations (Ile21 → Thr and Asp66 → Gly) in the coat protein (CP) gene and in symptoms produced in infected N" plants. The CP structure in TMV-U1 and ts21-66 virions was probed by tritium planigraphy. Compared with the wild-type CP, labeling of the N-terminal region of mutant CP was half as high and suggested its greater shielding. The role of this CP region in virus interactions with the N" resistance system is discussed. [ABSTRACT FROM AUTHOR]
