PTI pathway predicted to be induced in stigma after KEGG pathway mapping analysis. PTI pathway modified according to the information from Bigeard et al. 2015, Bi et al. 2018, and Lian et al. 2018. Genes in green boxes were upregulated (FC > 2) after compatible pollination, at 10 min and 60 min (light green), or only at 60 min (dark green: genes with SNPs, hatched dark green: genes without SNP but predicted stigma specific with ECM, see Supplementary file 8 Table S10). Gene in grey box was upregulated (FC > 2) 60 min after incompatible pollination. White boxes mean genes without SNPs (with no ECM prediction), not induced, or induced after both (compatible/incompatible) pollination (see Supplementary file 7 Table S9). Genes in bold were expressed at C0; nFPKM (stigma) > 1. RLCKs = Receptor-Like Cytoplasmic Kinases
