Figure 2.

Late-response genes in various functional categories respond coordinately to FRc irradiation in wild-type but not phyA-null mutant seedlings. The 24-h time-course expression profiles for all late-response genes in each category have been superimposed for the wild-type and phyA-null mutants separately by using genespring software. (Left) Genes induced by FRc. (Right) Genes repressed by FRc. All profiles are normalized to the maximum value in the time course for that gene. A single example profile has been highlighted for each category of induced (red) and repressed (blue) genes. The complete list of late-response genes is presented in Tables 6 and 7, supplemental material, with links to the separate time-course curves for each individual gene, at www.pgec.usda.gov/Quail/phyA.html.
