Ozone fumigation of tobacco caused a strong induction of basic ß-1,3-glucanase mRNA. In situ hybridization revealed a uniform labeling of the whole tissue section, except for the necrotic areas. Ozone-treated leaf parts showed an increased transcript accumulation, whereas no transcripts were detectable in non-treated leaf parts. Treatment of a single leaf increased ß-1,3-glucanase mRNA level only in this leaf and not in other leaves. Conversely, protection of a single leaf resulted in transcript accumulation only in the fumigated leaves. These results indicate that ozone-induced ß-1,3-glucanase mRNA accumulation is restricted to the ozone-treated area, and that ozone does not lead to systemic induction of this (PR) protein.
