Analysis of seed germination and root elongation of <i>GhMPK17</i> overexpression transgenic <i>Arabidopsis</i> under NaCl stress.

<p>(<b>A</b> to <b>C</b>) Seed germination rate of <i>GhMPK17</i> overexpression lines and wild type on MS medium containing different concentrations of NaCl. (<b>A</b>) Seeds germinated on MS medium (control). (<b>B</b>) Seeds germinated on MS medium with 50 mM NaCl. (<b>C</b>) Seeds germinated on MS medium with 100 mM NaCl. Each curve represents an average of three replicates. (<b>D</b> to <b>G</b>): Phenotype of wild type and <i>GhMPK17</i> overexpression seedlings under NaCl treatment. Seeds were germinated on MS medium under normal condition for 7 days and then the seedlings were transferred onto MS medium supplemented with 0 (<b>D</b>), 100 (<b>E</b>), 150 (<b>F</b>) and 200 (<b>G</b>) mM NaCl for 7 days. Each experiment was repeated at least three times with identical results. Bars = 1 cm. (<b>H</b> to <b>I</b>) Statistical analysis of root elongation of wild type and <i>GhMPK17</i> overexpression seedlings grown on MS medium as control (<b>H</b>) or MS medium supplemented 100 mM NaCl (<b>I</b>). Data were shown from three independent experiments, and bars indicate SDs. **, P<0.01. WT, wild type; L11, L24 and L46, <i>GhMPK17</i> transgenic line 11, 24 and 46.
