Schematic representation of defense activation by Trichoderma harzianum T34 in wheat seedlings. (A) Scheme of the major branch pathway of flavonoid biosynthesis, seven genes differently expressed in wheat seedling roots resulting from the GeneChip Wheat Genome Array analysis under different growth conditions with Trichoderma harzianum T34 and 0 (T1N0, green), 0.1 (T1N0.1, red), 0.5 (T1N0.5, blue) or 1 (T1N1, black) mM calcium nitrate belong to this pathway. Enzyme names are abbreviated as follows: Chalcone synthase (CHS), Naringenin 7-O-methyltransferase (NOMT) and Phenylalanine ammonia-lyase (PAL). (B) Signaling networks involving major genes related to plant-Trichoderma interaction that show upregulation (↑) or downregulation (↓) in the current study.
