Quantitative RT-PCR analysis of expression of PpGST genes in fruit under 0.2 mM IAA treatments.

Expression of PpGST1 and PpGST2 was analysed in 10 d after harvest fruit at 0.2 mM IAA treatment for 3, 6, 12, 24, and 36 h. Relative value of PpGST1 and PpGST2 expression in pear fruit including different time courses of 0.2 mM IAA treatment is 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.
