Fig. 3From: Identification of transcription factors interacting with a 1274 bp promoter of MaPIP1;1 which confers high-level gene expression and drought stress Inducibility in transgenic Arabidopsis thalianaGUS histochemical staining and fluorescent quantitative analysis of transgenic Arabidopsis expressing four truncated promoter of pMaPIP1;1::GUS under drought stress conditions. (a, c, e) GUS histochemical staining of transgenic Arabidopsis with 100 mM, 200 mM, 300 mM mannitol respectively. (b, d, f) GUS fluorescent quantitative analysis of transgenic Arabidopsis with 100 mM, 200 mM, 300 mM mannitol respectively. Values represent the mean ± standard deviation from three independent transgenic lines and each line five individual plants for each construct. Different lower case letters above the bars indicate significant differences at P < 0.05Back to article page
