Effects of TaGLDH-A1a and TaGLDH-A1b on leaf water loss value.

Among the eight Xinjiang wheat cultivars used, Achun 2, Qichun 5, Tuchun 6 and Yichun 4 had TaGLDH-A1a whereas Jiuchun 1, Kashibaipi, Redstar and Xinchun 3 possessed TaGLDH-A1b. (A) Water loss values of the eight cultivars determined at 2, 4 and 6 h after leaf detachment, respectively. The four cultivars with TaGLDH-A1b exhibited significantly reduced water loss (filled bars) than those carrying TaGLDH-A1a (open bars). The data shown are representative of three independent assays. (B) Water loss values scored at three different time points after leaf detachment (2, 4 and 6 h) for Yichun 4, Xinchun 3 and the F2 seedlings with A1aA1a (homozygous for TaGLDH-A1a), A1aA1b (heterozygous) or A1bA1b (homozygous for TaGLDH-A1b) genotype. The data depicted are representative of two independent assays. In both (A,B), each water loss value is the mean ± SD of three measurements using a pool of eight fully expanded leaves detached from eight separate plants. The histograms labelled by unidentical letters are statistically different (P < 0.05).
