Peak time distribution for circadian controlled and light responding genes. The graphs represent the peak time data for genes which were classified as (a) circadian controlled and (b) light responsive. The circle defines a polar coordinate plot with radians transformed to hours. The inner dotted circles represent a scale for the number of genes. The time points are plotted around the circle. Most of the circadian genes peak in the early dark, whereas light responding genes peak in the middle of either light or dark.
