Figure 5.

Number of genes defined as responding to 1 h of red light in 7 day old Arabidopsis seedlings using two column purification devices. Venn diagrams show the number of genes up- and down-regulated > 2-fold by red light of as detected by column B (left) and column D (right). Number of genes detected per column and overlapping between columns is expressed as percentage (%) of the combined gene list of up- and down-regulated respectively. Results form one independent slide is shown.
