gtl1 Plants Exhibit Higher Instantaneous WUE Due to Lower Transpiration and Stomatal Conductance.
Leaf transpiration, stomatal conductance, net CO2 assimilation, instantaneous WUE, internal CO2 concentration, and VPD were determined on individual leaves of 8-week-old wild-type (Col-0) and gtl1 plants (8-h diurnal photoperiod) using a Li-Cor 6400 gas exchange system (mean ± se, n = 4).
