Abstract: | Acibenzolar-S-methyl (ASM) is a chemical activator of systemic disease resistance in plants. In this study, we used differential
display to identify ASM-inducible defense response genes involved in induced disease resistance. As a result, we cloned three
ASM-inducible genes from cucumber, encoding a chitinase, a putative protein disulfide isomerase and a putative mitochondrial-protein-like
protein. Expression of these genes was induced within 24 hr after treatment of cucumber leaves with ASM. These results suggest
that differential display is a useful tool for understanding the mode of action of ASM and defense responses.
