Quantitative RT-PCR analysis of expression of <i>PpGST</i> genes in fruit under SA treatments.

<p>(<b>A</b>) Quantitative RT-PCR analysis of expression of <i>PpGST</i> genes in fruit under SA treatment for 12 h. Relative values of expression of <i>PpGST</i> genes in 20 d after harvest fruit treated with 0, 0.002, 0.02, 0.2 and 2 mM SA for 12 h, respectively, are shown as a percentage of β-actin expression activity. (<b>B</b>) Quantitative RT-PCR analysis of expression of <i>PpGST</i> genes in fruit under 0.2 mM SA treatment. Relative values of expression of <i>PpGST</i> genes in 20 d after harvest fruit treated with 0.2 mM SA for 0, 3, 6, 12, and 24 h, respectively, are shown as a percentage of β-actin expression activity. Mean values and standard errors (bar) were shown from three independent experiments. Values shown are means ±SD for three replicates. Independent t tests for equality of means demonstrated that there was significant difference (*P value<0.05) or very significant difference (**P value<0.01) between control and treated fruit.</p>
