Figure 5.

Effect of BHQ at the indicated concentrations and subsequently added 0.1 μm NodRm-IV(C16:2,S) on cytosolic free [Ca²⁺] (pCa_C) (a) and cytosolic [Cl⁻] (pCl_C) of M. sativa root hairs (b). At “//” drawings of curves are interrupted for 2 to 3 min to allow for normalization of Nod factor addition. The initial transients on the Ca²⁺ or Cl⁻ traces arise from the different response times of the two electrodes. External [Ca²⁺] was 0.1 mm. Kinetics are representative examples of four recordings each carried out under equivalent conditions.
