Figure 6.

The Arabidopsis tiling arrays portray several interesting classes of circadian behavior in the genome. Each symbol is a feature on the tilling array showing location in the genome (x-axis) and significance of the spectral analysis (y-axis) for (a) AT2G20400, (b) MIR167, (c) TRANS-ACTING siRNA3, and (d) transfrag-5-6839029. The top half of each panel displays the Watson strand and the bottom half the Crick strand. Individual features that exceed the false discovery rate 5% p-value threshold (-) are considered to have a circadian rhythm.
