Stomatal opening provides access to inner leaf tissues for many plant pathogens, so narrowing stomatal apertures may be advantageous for plant defense.

BITC at 50 M or more induced stomatal closing which was partially inhibited by diphenylene iodonium (DPI), N G -nitro-L-Arg-methyl ester (L-NAME) and catalase.
