| Research Abstract |
Salicylic acid (SA) or azelaic acid (AA) were administered to3-month-old Japanese birch plantlets. Two days after the treatments, proteins were extracted from the plantlets, separated by two-dimensional electrophoresis, and then the treatment-specific proteins were detected. As the results of analyses of these proteins, 11 and 8 kinds of proteins were identified from SA and AA treatments, respectively. The formers were involved in energy production, metabolisms, and protein syntheses, while the latters in photorespiration metabolism, sugar metabolism and ascorbic acid biosynthesis, fatty acid degradation, photosynthesis, photosystem I, defensive response, and molecular chaperone. Based on the obtained results, it was clarified that both SA and AA activate primary metabolism and energy production to induce systemic plant immunity in Japanese birch plantlet, although the induction mechanisms are different between them.
