ER-located PIN5 transporter generates potent auxin sinks driven by the IAA decarboxylation pathway

The paper shows that AtPIN5 in tobacco cells induces PCD and reveals its role in the auxin decarboxylation pathway.

Cytokinin Dehydrogenase in Xylem Sap Reveals A Direct Link Between Cytokinin Metabolism and Long-Distance Transport

This study identifies xylem-located cytokinin oxidase/dehydrogenase (CKX) activity in oats, showing its role in modulating root-to-shoot cytokinin translocation through metabolic degradation.

Study of auxin metabolism using stable isotope labeling and LCMS; evidence for in planta auxin decarboxylation pathway.

This study identifies an in planta auxin decarboxylation pathway using stable isotope labeling and LCMS in tobacco BY-2 cells and multiple plant species.

Auxin coreceptor IAA17/AXR3 controls cell elongation in Arabidopsis thaliana root by modulation of auxin and gibberellin perception

This study shows that AXR3-1 modulates auxin and gibberellin perception to control cell elongation in Arabidopsis root, leading to altered growth and homeostasis.

Non-specific effects of a CINNAMATE-4-HYDROXYLASE inhibitor on auxin homeostasis

This study shows that a C4H inhibitor, piperonylic acid, affects auxin homeostasis by interfering with auxin conjugation through GH3.6, leading to increased cellular auxin levels and altered plant growth.

A role of DAO1 in oxidation of IAA amino acid conjugates revealed through metabolite, high throughput transcript and protein level analysis.

The paper identifies DAO1's role in oxidizing IAA amino acid conjugates through metabolite, transcript, and protein analysis in tobacco cells.
