Differential gene expression upon Benz and Tolf treatments. (a) Principal component analysis (PCA) of the diversity of gene expression in treatment groups. PC 1 allows discrimination among seasons (T0 and T2). PC 3 allows discrimination between the three treatment conditions (Benz, Tolf and Control) as indicated. No significant variation was observed between the three treatment conditions. (b) Venn diagrams of downregulated (left) and upregulated (right) genes following treatment with Tolf (T; yellow circle) or Benz (B; green circle).
