Gibberellins promote polar auxin transport to regulate stem cell fate decisions in cambium. [PDF]
Nat Plants, 2023 Auxin is a key regulator in vascular cambium development. This study shows that gibberellins promote polar auxin transport along the root, which leads to broadening of high auxin signalling domain in cambium, and thus, to increased xylem formation ...

Coordination of tissue cell polarity by auxin transport and signaling [PDF]
eLife, 2019 Plants coordinate the polarity of hundreds of cells during vein formation, but how they do so is unclear. The prevailing hypothesis proposes that GNOM, a regulator of membrane trafficking, positions PIN-FORMED auxin transporters to the correct side of ...

GmPIN-dependent polar auxin transport is involved in soybean nodule development. [PDF]
Plant Cell, 2021 To overcome nitrogen deficiency, legume roots establish symbiotic interactions with nitrogen-fixing rhizobia that are fostered in specialized organs (nodules). Similar to other organs, nodule formation is determined by a local maximum of the phytohormone

Cell kinetics of auxin transport and activity in Arabidopsis root growth and skewing. [PDF]
Nat Commun, 2021 Auxin is a key regulator of plant growth and development. Local auxin biosynthesis and intercellular transport generates regional gradients in the root that are instructive for processes such as specification of developmental zones that maintain root ...

Flavonol-mediated stabilization of PIN efflux complexes regulates polar auxin transport. [PDF]
EMBO J, 2021 The transport of auxin controls the rate, direction and localization of plant growth and development. The course of auxin transport is defined by the polar subcellular localization of the PIN proteins, a family of auxin efflux transporters.

Connective auxin transport contributes to strigolactone-mediated shoot branching control independent of the transcription factor BRC1. [PDF]
PLoS Genetics, 2019 The shoot systems of plants are built by the action of the primary shoot apical meristem, established during embryogenesis. In the axil of each leaf produced by the primary meristem, secondary axillary shoot apical meristems are established.

Strigolactones inhibit auxin feedback on PIN-dependent auxin transport canalization. [PDF]
Nat Commun, 2020 Directional transport of the phytohormone auxin is a versatile, plant-specific mechanism regulating many aspects of plant development. The recently identified plant hormones, strigolactones (SLs), are implicated in many plant traits; among others, they ...

All Roads Lead to Auxin: Post-translational Regulation of Auxin Transport by Multiple Hormonal Pathways [PDF]
Plant Communications, 2020 Auxin is a key hormonal regulator, that governs plant growth and development in concert with other hormonal pathways. The unique feature of auxin is its polar, cell-to-cell transport that leads to the formation of local auxin maxima and gradients, which ...
