Figure 4. Venn Diagram showing similarity and differences between genes. The diagram is applied to three sets of regulated entities: those regulated by light damage (LD; compared to control); those regulated by LD when preceded by photobiomodulation (PBM; compared to control); and those regulated by LD when preceded by saffron feeding (compared to control). These sets were selected by two-sample Student t test analysis (p<0.05) and fold-change (FC>2).
