Mp2g26590	MpCOI1	experimental subject	RT-qPCR measured expression of this JA-action (coronatine-insensitive 1) gene in M. polymorpha. Like LOX1 it rose significantly only with strains T87, T120, T123 and R. solani, used to determine whether the JA defense pathway was engaged.
Mp2g20660	MpICS	experimental subject	RT-qPCR measured expression of this SA-biosynthesis (isochorismate synthase) gene in M. polymorpha inoculated with Trichoderma strains at 10 and 30 dpi. Expression increased significantly with strains T6, T11, T25, T34 and T77, indicating activation of SA biosynthesis during the interaction.
Mp2g00660	MpLOX1	experimental subject	RT-qPCR measured expression of this JA-biosynthesis (lipoxygenase) gene in M. polymorpha. No changes were seen with most strains, but a significant increase occurred after inoculation with T87, T120, T123 and the pathogen R. solani, distinguishing JA- from SA-activating interactions.
Mp3g14110	MpPR1	experimental subject	RT-qPCR measured expression of this SA-action marker (pathogenesis-related protein 1) in M. polymorpha after Trichoderma inoculation. PR1 increased significantly alongside ICS, used as readout that the SA defense pathway was activated by certain fungal strains.
Mp3g23400	MpEF1	experimental tool	Elongation Factor 1 of M. polymorpha used as the internal reference gene for normalizing RT-qPCR expression data.
