From: Coordination of the maize transcriptome by a conserved circadian clock
Genes associated with phytohormone biosynthesis, flowering time, phototropism, and the circadian clock exhibited rhythmic expression. A) Expression waveforms of high confidence cycling biosynthesis genes for ethylene (green open symbols), ABA (blue closed symbols) and GA (red open symbols). B) Expression waveforms of high confidence cycling genes for phototropism (blue closed squares), circadian clock (green closed symbols), and flowering time (red open symbols). Shaded regions represent subjective night. For each gene, the normalized expression values from the array were further normalized to the highest expression value for that gene.
