Comparison among differentially expressed genes in both plant lines with and without peptide treatment. A) Venn diagram comparing differentially expressed genes in all three treatments. Genes marked “Bright green” are common between both plant lines after PSY1 treatment, genes marked “gray” are differentially expressed in all three treatments. Genes marked with “violet color” are common between peptide-treated wild type and untreated psy1r mutant plants. Genes marked with “yellow”, “blue color” and “pink color” are solely expressed in one treatment but absent in the other treatments. The 112 genes marked with “orange” are common between treated and untreated psy1r mutant plants. B) Venn diagram of PSY1-responsive genes. Grey: genes differentially expressed in both plant lines after PSY1 treatment, blue and pink represents genes induced in wild type and in psy1r mutant plants, respectively, after PSY1 exposure.
