Distribution of differentially expressed genes after peptide treatment. A z-test for two independent conditions was conducted for each peptide treatment compared to the control treatment. Effective p-values were <3.3E-03 and <3.7E-03 for PAF26 and melittin, respectively. Diagram shows genes induced (up) or repressed (down) by peptides. The small circles on the upper part refer to 15 genes induced by PAF26 and repressed by melittin and 7 genes induced by melittin and repressed by PAF26.
