From: Coordination of the maize transcriptome by a conserved circadian clock
The maize circadian system directed phase-specific expression of genes involved in biosynthesis. Fraction of all genes in each phase cluster with GO Slim terms GO: 0015979 "photosynthesis" (PS, green), GO: 0006519 "cellular amino acid and derivative metabolic process" (AM, blue), and GO: 0009058 "biosynthetic process" (BP, yellow) compared to all genes on the microarray (AG, red). Hypergeometric distribution analysis from Table 2 indicated GO: 0015979 "photosynthesis" genes are overrepresented at midday (ZT4), whereas GO: 0006519 "cellular amino acid and derivative metabolic process" and GO: 0009058 "biosynthetic process" were enriched at early morning (ZT20).
