Circadian expression patterns for selected GATA genes. The expression of genes with a significant level of expression in light-grown seedlings collected over a circadian time course was analyzed over a time course designed to identify genes showing evidence of clock regulation in the absence of light signaling, following standard procedures. Gene expression was measured by qPCR analysis of cDNA from samples of light-grown seedlings collected every 4 h. Results presented show two biological replicates (dashed lines) and the average (with se bars) of duplicate analysis of the two biological replicates.
