While IAA is also produced from Trp via indole-3-acetaldoxime in Arabidopsis, this pathway likely plays an auxiliary role in plants of the family Brassicaceae. Recent studies suggest that the Trp-independent pathway is not a major route for IAA biosynthesis, but they reveal an important role ...
A phosphorylation-based switch controls TAA1-mediated auxin biosynthesis in plantsAuxinPlant signallingAuxin determines the developmental fate of plant tissues, and local auxin concentration is precisely controlled. The role of auxin transport in modulating local auxin concentration has been widely studied ...
Yucasin suppressed high-auxin phenotypes of Arabidopsis YUC overexpression plants, but showed weak inhibitory activity on root growth of wild-type seedling (Supplemental Fig. S5)21. To develop a more potent auxin biosynthesis inhibitor, we synthesized various analogs of yucasin. In our previous study...
YDF caused an auxin-deficient phenotype in Arabidopsis wild-type plants that was restored with auxin application. YDF was found to be highly stable regarding metabolic conversion in vivo, accounting for the potent activity of the inhibition of IAA biosynthesis in planta. Photoaffinity labeling ...

In this perspective, we are proposing the non-enzymatic regulation of redox homeostasis and auxin biosynthesis throughout the plant body under variable environmental light conditions. 展开 关键词: Light Auxin Tryptophan Flavin Reactive oxygen species ...
So far, no single complete pathway of de novo auxin biosynthesis in plants has been rmly established. However, recent studies have led to the discoveries of several genes in tryptophan-dependent auxin biosynthesis pathways. Recent ndings have also determined that local auxin biosynthesis plays ...

production in plants have not been solved. The understanding of the iaaM / iaaH pathway has been instrumental to recent progress in dissecting auxin biosynthesis in plants. The bacterial iaaM gene also provides a useful way to manipulate auxin levels in transgenic plants. Overexpression of the iaaM...
