Inoculation of the lower leaves of Nicotiana tabacum var. Samsun NN with tobacco mosaic virus (TMV) induced resistance to challenge inoculation of TMV in the upper leaves 7 days after the primary inoculation. Development of the systemic, acquired resistance was inhibited by treatments of the inoculated leaves with blasticidin S and formycin B, but not by treatments with chleramphenicol, cycloheximide and 2-thiouracil. The inhibitory effect of blasticidin S was exhibited only when it was applied within 12 hr after the primary inoculation. This suggests that de novo synthesis of mRNA or protein (s) might be associated with the development of systemic acquired resistance. Fourteen days after the primary inocuiation, two newly formed protein species were found in the electrophoregrams of extracts from the inoculated and the upper uninoculated leaves. No significant change in the protein electrophoregram of the upper uninoculated leaves was observed when the lower inoculated leaves were treated with blasticidin S. This result indicates that the two protein species are not directly connected with the induction of systemic, acquired resistance.
