Elicitor-Induced Changes in [Ca²⁺]_cyt in Apoaequorin-Transformed Parsley Cells.

Bioluminescence of reconstituted aequorin was monitored in parsley cells treated with water or Pep-13 at the time (arrow) indicated.

(A) Addition of water or 100 nM Pep-13, respectively.

(B) Addition of Pep-13 at the concentrations indicated. Numbers in parentheses represent amounts of phytoalexins produced by parsley cells treated with the given Pep-13 concentrations relative to those produced by cells treated with 100 nM Pep-13.
