Research Abstract

Hypersensitive response (HR) is a strong immune response in plants. In order to define activation patterns of defense responses involved in hypersensitive response (HR), I have constructed promoter-reporter transgenic Arabidopsis plants of PR-1 and SID2 genes, respectively. Imaging analysis using these plants challenged with HR-triggering pathogen indicated that these two genes are differentially regulated in spatial aspects. In addition, I have constructed transgenic Arabidopsis plants carrying an inducible Avr gene upon stimuli. These plants enabledus to induce an artificial HR locally.
