Figure 2.

Real-time Q-PCR validation of diurnal genes. For each gene, the expression pattern detected by Q-PCR (lower panel) was compared with that detected by microarray (upper panel). Data shown are mean ± standard error for three biological replicates in the microarrays, and for five biological replicates in Q-PCR experiments. The Q-PCR results gave similar patterns to those detected by the microarray for 16/18 diurnally regulated genes.
