Combinations of ethylene and methyl jasmonate (E/MeJA) synergistically induced members of both groups 1 and 5 of the pathogenesis-related (PR) superfamily of defense genes. E/MeJA caused a synergistic induction of PR-1b and osmotin (PR-5) mRNA accumulation in tobacco seedlings. E/MeJA also synergistically activated the osmotin promoter fused to a [beta]-glucuronidase marker gene in a tissue-specific manner. The E/MeJA responsiveness of the osmotin promoter was localized on a -248 to +45… CONTINUE READING
