Amplitude of the first [Ca²⁺]_cyt peak from luminometric measurements of Col-0 and C24 in response to [NaCl] and [sorbitol] treatment.

<p>The 13 d to 15 d old Col-0 (square symbol) and C24 (triangular symbol) seedlings constitutively expressing <i>aequorin</i> were treated with a range of NaCl and corresponding equal osmotic strength of sorbitol concentrations (which can be approximated to 2 times [NaCl]). Each point represents the average peak height of the first [Ca²⁺]_cyt peak of three replicates, error bars indicate the standard error of the mean (S.E.M.).</p

Luminometric measurements of whole Arabidopsis seedlings, constitutively expressing <i>aequorin</i>.

<p>Alterations of [Ca²⁺]_cyt induced by (A) 200 mM NaCl, (B) 400 mM sorbitol, (C) 9°C cold treatment or (D) base solution in ecotype Col-0 and (E) 200 mM NaCl, (F) 400 mM sorbitol, (G) 9°C cold treatment or (H) base solution in ecotype C24. Each panel contains data from three to six representative individual seedlings. Stimulus (stress) was applied at time point 0.</p
