Table 1 Experimental differences in original circadian microarray analyses
Publication | % Circadian | Number of time points | Light intensity (μmol/m2 per second) | Microarray platform | Technical replicates | Low-level analysis | Circadian detection algorithm | Presence cut-off |
|---|---|---|---|---|---|---|---|---|
Harmer and coworkers [4] | 5.5 | 12 | 60 | Affymetrix Arabidopsis Genome | 2 | Affymetrix MAS 4.0 | CORRCOS | None |
Edwards and coworkers [6] | 15.4 | 13 | 60 to 65 | Affymetrix Arabidopsis ATH1 | N/A | GC-RMA | COSOPT (less stringent) | None |
Covington and Harmer [7] | 10.4 | 12 | 120 | Affymetrix Arabidopsis ATH1 | N/A | dChip | COSOPT (more stringent) | Genes present in ≥ 4 of 12 samples |
