(a) Expression of MED4 genes encoding PSI and PSII, cytochrome b₆f and pnt genes in the gas shock experiment. Data points are the geometric means of two biological replicates. Fold change is relative to t=0 for each condition. Shock conditions causing significant differential expression in the air control with respect to time 0 are highlighted in blue; shock conditions causing significant differential expression over the time course with respect to air are highlighted in red. Ninety percent of data points lie within the outer (light) shaded bands; 70% lie within the inner (dark) bands. (b) Oxygen dependence of the cluster affiliations of the genes in panel a under carbon limitation. No differentially expressed genes in this set fell into cluster 1 (increased expression) or 2 (delayed recovery). See Figure 2b for cluster profiles.
