Abstract
An isolate of tobacco mosaic virus (TMV-A) was obtained from healthy and sunblotch-infected avocado (Persea americana) seedlings. TMV-A resembled common TMV in particle morphology, RNA size and coat protein molecular weight. TMV-A coat protein differed from common TMV coat by a minimum of 22 amino acid exchanges including the presence of one methionine, and by the absence of cysteine. Spur formation between the precipitation lines of TMV, TMV-A and a TMV antiserum indicates certain differences among the antigenic determinants of these two strains.
