Analysis of stomatal aperture, water loss rate, and photosynthetic in WT and OE tobacco lines. (a, b) Light microscopic observation of WT and OE lines stomata under control conditions and 200 mM mannitol conditions (c) Photosynthetic rates (d) Water loss rates. Data were represented as the mean ± SE of three biological replicates; statistical significance (P < 0.05) between mannitol treatments is indicated by a, b, and c
