Reduced transpiration and improved integrated WUE in IDD16‐OE plants. (a) Diurnal transpiration rate and (b) light period water loss of 5‐week‐old wild‐type and 35S:IDD16m plants grown under a 12‐h‐light/12‐h‐dark photoperiod were determined by gravimetric analysis. Values are means ± SE from four biological replicates, with each replicate include more than 12 plantlets. (c) Water use efficiency (WUE) as determined by the sum of daily transpiration and biomass production over 7 days. Plants were grown under a light intensity of PAR = 120 μmol/m2/s. Values are means ± SE from three biological replicates, with each replicate include more than 20 plantlets. (d) Leaf transpiration and (e) instantaneous WUE were determined on individual leaves of 5‐week‐old wild‐type (Col‐0) and 35S:IDD16m plants using a Li‐Cor 6400 gas exchange system, values are the Mean ± SE (n = 4). Asterisks indicate statistical significance based on Student's t test; ** P < 0.01, * P < 0.05.
