| Begin | 704 | Description | In pen3-5; slight overaccumulation in leaves of 4-O-beta-D-glucosyl-indol-3-yl formamide (4OGlcI3F) upon Blumeria graminis conidiospore inoculation, a pathogen-inducible tryptophan-derived compound, which biosynthesis is dependent on the PEN2 metabolic pathway. Fully defective in preinvasive defense to nonadapted powdery mildews (e.g. Blumeria graminis and Erysiphe pisi). Normal susceptibility to the host-adapted pathogen Golovinomyces orontii associated with normal salicylic acid (SA) pathogen-inducible hydrogen peroxides levels. Retained microbe-associated molecular patterns (MAMPs)-induced (e.g. flg22) callose deposition. Increased susceptibility to the necrotrophic pathogen Plectosphaerella cucumerina. Enhancer mutation of the mutant pen2-dependent invasive growth of Blumeria graminis. Normal insensitivity to indole-3-butyric acid (IBA), an auxin precursor. Normal accumulation (at protein level). |
