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.

Ectopic assembly of an auxin efflux control machinery shifts developmental trajectories

The paper shows that ectopic PAX-BRX-PIP5K module assembly reduces PIN abundance and alters root growth by accelerating xylem vessel differentiation.

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.

Phytohormone profiling in an evolutionary framework

This study profiles phytohormones across streptophyte algae, chlorophyte algae, and early land plants to trace their evolutionary origins and distribution.

The AUX1-AFB1-CNGC14 module establishes longitudinal root surface pH profile

The paper identifies a module involving AUX1, AFB1, and CNGC14 that regulates root surface pH gradients, crucial for root navigation.

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.

Mutually opposing activity of PIN7 splicing isoforms is required for auxin-mediated tropic responses in Arabidopsis thaliana

The paper shows that PIN7 splicing isoforms PIN7a and PIN7b have opposing activities essential for auxin-mediated tropic responses in Arabidopsis thaliana.
