Fig. 1From: Overexpression of γ-glutamylcysteine synthetase gene from Caragana korshinskii decreases stomatal density and enhances drought toleranceThe stomatal density of Caragana korshinskii with different precipitation areas from Loess Plateau in China. Scanning electron micrographs of C. korshinskii leaves in Ansai, Shenmu, Dongsheng (a-c). The stomatal density of the C. korshinskii leaf with three sites (d). The data were shown above as means±SD (n ≥ 3). * and ** indicate that compared with Ansai, P < 0.05 and P < 0.01Back to article page
