| Begin | 1357 | Description | In pdr8-115 and pen3-6; 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. Hypersensitivity to root growth inhibition by 2,4-dichlorophenoxybutyric acid (2,4-DB), an analog of indole 3-butyric acid (IBA), an auxin precursor. 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), and pathogen-inducible hydrogen peroxides levels. Retained microbe-associated molecular patterns (MAMPs)-induced (e.g. flg22) callose deposition. Suppressor of a subset of ibr5 mutant phenotypes including IBA sensitivity but without suppressing ibr5 resistance to indole-3-acetic acid (IAA). Normal accumulation (at protein level). |
