Gas exchange measurements on transgenic sugarcane submitted to drought stress. (a) Stomatal conductance (mol/m²/s) and (b) CO ₂ assimilation rate (μmol/m²/s) sugarcane adult plants undergoing continuous irrigation (controls) and under drought condition. Plants belonging to ScBI‐3 and ScBI‐4 events have shown AtBI‐1 gene expression controlled by Ubi‐1 promoter. Each symbol corresponds to the average value (n = 5) ± SD. I, irrigated; NI, nonirrigated; VC, vector‐only control; WT, wild‐type plants.
