Abstract

The results obtained by laser scanning confocal microscopy suggested that addition of exogenous aBA resulted in a rapid decrease in fluorescence in most cellular compartments of the guard cells. Above data support the hypothesis that H_(2)O_(2) is involved in the signal transduction pathway of ABA-induced stomatal closure.
