Figure 2.

Wound-induced systemic potentials between the root and SE/CCs in neighbor leaves of Arabidopsis thaliana wild type and GLR mutants. Typical wound-induced potentials of a wild type plant (A), as well as of the single mutants glr3.3a (B), glr3.6b (C), and glr3.5a (D) are shown. The inset illustrates the design for these experiments. In all cases except in the glr3.6 mutant, the recordings show unambiguously 2 potentials, a long potential and a superimposed action potential, annotated as LP and AP in (A). The time of wounding is indicated with arrows.
