Comparison of results obtained by microarray-analysis and by qPCR-analysis. On y-axis, positive M-values indicate more expression in WL, whereas negative M-values indicate more expression in RJ. Nine genes included in qPCR-analysis are presented along x-axis. To indicate statistical significance in real-time PCR at the p < 0.05 level the * symbol is used. To indicate q-values < 0.015 in the microarray analysis the ‡ symbol is used.
