Combined in silico/in vivo analysis of mechanisms providing for root apical meristem self-organization and maintenance. [PDF]

, 2012
Background and aimsThe root apical meristem (RAM) is the plant stem cell niche which provides for the formation and continuous development of the root.

Cellular Auxin Transport in Algae

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.

Subcellular trafficking and post-translational modification regulate PIN polarity in plants

Frontiers in Plant Science, 2022
Auxin regulates plant growth and tropism responses. As a phytohormone, auxin is transported between its synthesis sites and action sites. Most natural auxin moves between cells via a polar transport system that is mediated by PIN-FORMED (PIN) auxin ...

SHADE AVOIDANCE 4 is required for proper auxin distribution in the hypocotyl [PDF]

, 2016
The phytohormone auxin is involved in virtually every aspect of plant growth and development. Through polar auxin transport, auxin gradients can be established, which then direct plant differentiation and growth.

An auxin-driven polarized transport model for phyllotaxis [PDF]

Proceedings of the National Academy of Sciences, 2006
Recent studies show that plant organ positioning may be mediated by localized concentrations of the plant hormone auxin. Auxin patterning in the shoot apical meristem is in turn brought about by the subcellular polar distribution of the putative auxin efflux mediator, PIN1.

Alignment between PIN1 Polarity and Microtubule Orientation in the Shoot Apical Meristem Reveals a Tight Coupling between Morphogenesis and Auxin Transport [PDF]

, 2010
Morphogenesis during multicellular development is regulated by intercellular signaling molecules as well as by the mechanical properties of individual cells.

Connective Auxin Transport in the Shoot Facilitates Communication between Shoot Apices.

PLoS Biology, 2016
The bulk polar movement of the plant signaling molecule auxin through the stem is a long-recognized but poorly understood phenomenon. Here we show that the highly polar, high conductance polar auxin transport stream (PATS) is only part of a multimodal ...

Keeping it all together: auxin–actin crosstalk in plant development [PDF]

, 2015
Polar auxin transport and the action of the actin cytoskeleton are tightly interconnected, which is documented by the finding that auxin transporters reach their final destination by active movement of secretory vesicles along F-actin tracks.

ELECTRICAL POLARITY AND AUXIN TRANSPORT [PDF]

Plant Physiology, 1937
The polar basal transport of the growth substances (auxins, growth hormones) in plants is a well known phenomenon, demonstrated first by Went (81), and studied in detail by van der Weij (78, 80). These investigators used the Avena (oat) coleoptile.1 That the phenomenon is more or less general is indicated by the polar transport of auxin in roots ...

Auxin Polar Transport is Essential for the Early Growth Stage of Etiolated Maize (Zea mays L. cv. Honey Bantam) Seedlings

Plant Production Science, 2014
The important role of auxin polar transport in the early growth stage of etiolated maize (Zea mays L. cv. Honey Bantam) seedlings was intensively studied.
