additional information | construction of taa mutants showing phenotypes including defects in shade avoidance, root resistance to ethylene and N-1-naphthylphthalamic acid, the phenotypess are phenocopied by inactivating YUC genes, overview. Overexpression of YUC1 partially suppresses the shade avoidance defects of taa1 and the sterile phenotypes of the weak but not the strong taa mutants. The auxin overproduction phenotypes of YUC overexpression lines are dependent on active TAA genes. Construcction of wei8 tar2 mutants, phenotypes, overview | Arabidopsis thaliana |

General Information | Comment | Organism |
---|---|---|
malfunction | taa mutants are partially indole-3-pyruvate-deficient, indicating that TAAs are responsible for converting tryptophan to indole-3-pyruvate. Inactivation of TAA1/TIR2 causes root resistance to the auxin transport inhibitor naphthylphthalamic acid | Arabidopsis thaliana |
metabolism | tryptophan aminotransferase of Arabidopsis thaliana, TAA, and YUCCA work in the same pathway and that YUC is downstream of TAA. The TAA family of amino transferases converts tryptophan to indole-3-pyruvate, and the YUC family of flavin monooxygenases participates in converting IPA to indole-3-acetic acid, the main auxin in plants | Arabidopsis thaliana |
