From: A novel Glycine soja homeodomain-leucine zipper (HD-Zip) I gene, Gshdz4, positively regulates bicarbonate tolerance and responds to osmotic stress in Arabidopsis

Overexpression of Gshdz4 enhanced tolerance to NaHCO3 stress in germination stage. a Transcription levels of Gshdz4 in transgenic Arabidopsis (#14, #20 and #23) and WT by RT-PCR. b NaHCO3 stress tolerance of Gshdz4 transgenic Arabidopsis (#14, #20 and #23). Plant growth under normal condition and under NaHCO3 stress (0, 6 or 7 mM NaHCO3). c Plant survival rates under NaHCO3 stress (0 or 6 mM NaHCO3). Values represent means of three biological replicates; error bars indicate SD. Significant differences are denoted with one or two stars if P < 0.05 or P < 0.01, by Student’s t-test
