The wild type (WT) exhibits a lower stomatal conductance, but greater transpirational water loss for any given conductance than d1. (A) The WT exhibits a lower stomatal conductance than d1 under well-watered conditions; conductances converge as the relative soil water content (RSWC) decreases. Data were fitted to a saturating exponential model (Supplementary Table S6). (B) Transpiration rates did not differ between the WT and d1. Data were fitted to a saturating exponential equation (Supplementary Table S7).
