Figure 6.

Dependence of the overall [Ca²⁺]_c kinetic on the location of the primary stimulus and on the number of primarily stimulated cells in the ‘young-seedling configuration’. (A) All cells of the left cotyledon are stimulated simultaneously; (B) The surface cells of both cotyledons are stimulated; (C) Two meristematic cells are stimulated; (D) The root tip only is stimulated. (E) Dependent on the site of stimulation and the number of primarily stimulated cells, very different [Ca²⁺]_c kinetics are obtained from the whole system.
