Figure 5From: APUM5, encoding a Pumilio RNA binding protein, negatively regulates abiotic stress responsive gene expressionAnalysis of salt sensitivity in wild type and APUM5 transgenic plants in soil. (A) Photographs show plants treated with 150 mM NaCl at the indicated time points. Four-week-old Col-0, 35S-APUM5, and APUM5-RNAi plants were treated with 150 mM NaCl. (B) Chlorophyll contents of salt-treated plants on day 10. Pigments were extracted from the salt-treated plant leaves. Data are mean values of six independent experiments. (C) Chlorophyll a/b ratio of salt-treated plant leaves. Error bars represent ± SD (Student’s t-test; *P < 0.01).Back to article page
