Validation of microarray data using qRT-PCR. Microarray results of twenty representative genes are confirmed by qRT-PCR. Expression of each gene in the A. thaliana exposed to a 1000 Hz sound vibration (gray) was compared with that of control plants (black). AtGAPDH was used for normalization. Bars represent mean and standard error of three biological replications. The time (0, 12, 24 and 48 h) indicates h post inoculation (hpi). Details of genes and their fold changes in microarray experiment are available in Table 1. P-value ranges are marked by asterisks: *** P < 0.01, ** 0.01 < P < 0.05, * P < 0.1.
