| Outline of Final Research Achievements |
To clarify if the trichome-dependent immune system is a general response, a wide variety of plants with different leaf structures were subjected to mechanical stimulation. We found MAPK activation as a typical response of mechanosensitive immunity.
Then, various plants were mechanically stimulated and used for RNA-seq analysis. In each plant species, the homologs of the mechanosensitive genes identified in Arabidopsis thaliana were confirmed. The expression levels of these genes were significantly increased in most samples. Finally, GO analysis revealed that mechanical stimulation activates plant immunity in these plants.
