Fig 4. Auxin-induced Ca²⁺ responses are reduced in cmi1 in a tissue-specific fashion.

Auxin-induced Ca²⁺ responses in lateral root cap (A and B), epidermis (C and D), and vascular tissues (E and F). Note the reduced Ca²⁺ levels and different kinetics in Ca²⁺ decrease and increase in the lateral root cap and the vascular tissues, respectively. Error bars are SE. Underlying data for this figure can be found in S1 Data. cmi1, Ca²⁺-dependent modulator of ICR1; wt, wild type.
