Scheme of the phenylpropanoid pathway. The expression profiles of all pea genes, which are responsive to at least one treatment (P ≤ 0.05), involved in the phenylpropanoid pathway during early interaction with A. euteiches and P. pisi are shown in the tables in the figure. Numbers in the coloured boxes represent the fold change (FC) in expression. P6 and A6 correspond to FC at 6 hpi while P20 and A20 correspond to FC at 20 hpi in response to P. pisi and A. euteiches, respectively, compared to mock-inoculated control samples. Asterisks indicate FC values that are differentially expressed (0.67 > FC > 1.5). The heat map goes from blue to red with increasing expression values. Arrows represent enzymatic reactions. The abbreviations marked in red indicate that at least one gene member of the family is differentially regulated at least in one treatment. Abbreviations: phenylalanine ammonia-lyase (PAL), cinnamic acid 4-hydroxylase (C4H), 4-coumarate-CoA ligase (4CL), cinnamoyl-CoA reductase (CCR), shikimate O-hydroxycinnamoyltransferase (HCT), caffeoyl-CoA O-methyltransferase (COMT), cinnamyl-alcohol dehydrogenase (CAD), chalcone synthase (CHS), naringin 3-dioxygenase (F3H), 2-hydroxyisoflavanone synthase (IFS), 2-hydroxyisoflavanone dehydratase (HID) and isoflavone O-methyltransferase (I7OMT)
