Cellular Auxin Transport in Algae [PDF]
Plants, 2014 The phytohormone auxin is one of the main directors of plant growth and development. In higher plants, auxin is generated in apical plant parts and transported from cell-to-cell in a polar fashion.

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 ...

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 ...

Strigolactones inhibit auxin feedback on PIN-dependent auxin transport canalization. [PDF]
Nat Commun, 2020 AbstractDirectional 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 modify the phenotypic output of PIN-FORMED (PIN) auxin transporters for fine-tuning of growth

Leaf vein patterning is regulated by the aperture of plasmodesmata intercellular channels
PLoS Biology, 2022 To form tissue networks, animal cells migrate and interact through proteins protruding from their plasma membranes. Plant cells can do neither, yet plants form vein networks.

Advances in the Biological Functions of Auxin Transporters in Rice
Agriculture, 2022 Auxin is the earliest discovered plant hormone, which plays important roles in each aspect of plant growth and development. There are two main pathways for auxin to be transported from the synthetic site (such as young leaves and terminal buds) to the ...

Polar Auxin Transport and Asymmetric Auxin Distribution [PDF]
The Arabidopsis Book, 2007 In all multicellular organisms extensive communication is required between cells and tissues in order to coordinate growth and development. Both plants and animals have signaling chemicals, traditionally termed hormones that mediate short- and long-distance communication.

The Transportable Auxin Pool [PDF]
Plant Physiology, 1970 Evidences from experiments with stem sections of sunflower seedlings suggest that the transport of auxin may be limited by a restricted pool size of transportable auxin and restrictions in the availability of transport sites. A steady state of transport is observed over a range of lengths of stem sections, and over a wide range of auxin contents.
