| 2.6.1.99 | evolution |
TAA1 encodes a member of a small family of aminotransferases with strong sequence similarity to C-S Lyases |

L-kynurenine, being an alternate substrate, competitively inhibits TAA1/TAR activity, and Kyn treatment mimicks the loss of TAA1/TAR functions |

SAV3 mutants are unable to elongate in simulated shade light, phenotypes, overview. Other indole acetic acid biosynthetic pathways cannot compensate for the loss of the SAV3-dependent pathway. sav3 mutants have reduced auxin levels and a diminished auxin response, and sav3 mutants exhibit shorter hypocotyls than WT when grown in simulated shade and partially suppress the constitutive shade avoidance phenotype of a phyB null mutant, sav3-1 plants are shorter and have reduced leaf hyponasty as compared to wild-type plants. The sav3-1 mutant fails to induce shade avoidance syndrome, SAS, in a controlled environment typically used to detect PHYB-mediated SAS responses in light-grown plants |

significantly lower levels of free for indole 3-acetic acid are detected in the single wei8-2 as well as in the double wei8-2 tar2-1 mutants |

| 2.6.1.99 | 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 |

| 2.6.1.99 | malfunction |
the ethylene defects of wei8 are dramatically enhanced in the wei8 tar2 double mutants that display a nearly complete lack of response to ACC in roots |

| 2.6.1.99 | malfunction |
vt2 mutants have dramatic effects on vegetative and reproductive development, decrease in leaf number in vt2 mutants, reduced tassel length in vt2 mutants is likely due to reduced cell elongation. In addition to male inflorescence defects, vt2 mutants also show severe defects in the female inflorescence, absence of branches and spikelets in vt2 inflorescences. spi1/vt2 double mutants have only a slightly more severe phenotype than vt2 single mutants. Both spi1 and vt2 single mutants exhibit a reduction in free auxin levels, but the spi1/vt2 double mutants do not have a further reduction compared with vt2 single mutants |

| 2.6.1.99 | metabolism |
gene wei8 encodes a long-anticipated tryptophan aminotransferase, TAA1, in the essential indole-3-pyruvic acid branch of the auxin biosynthetic pathway, a link between local auxin production, tissue-specific ethylene effects, and organ development exists. TAA1 and TAR2 have overlapping roles in the ethylene response, overview |
-, 719255 |
| 2.6.1.99 | metabolism |
the TAA family produces indole-3-pyruvic acid, and the YUC family functions in the conversion of indole-3-pyruvic acid to indole 3-acetic acid in Arabidopsis thaliana |
