ELECTRICAL POLARITY AND AUXIN TRANSPORT [PDF]
Plant Physiology, 1938 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 ...

A Retro-Perspective on Auxin Transport. [PDF]
Front Plant Sci, 2021 The transport of the plant hormone auxin has been a hotspot in plant biology since its discovery (Darwin and Darwin, 1880; Zazimalova et al., 2010; Friml, 2021; Hammes et al., 2021). After its identification and verification as IAA (3-indolyl acetic acid; Went and Thimann, 1937), auxin gained high interest and fascination in the plant community but ...

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.

Kinetics of Polar Auxin Transport [PDF]
Plant Physiology, 1966 The movement of auxin in the basipetal and acropetal directions is compared for 4 types of tissue. It is observed that the transport may proceed in either a linear or a non-linear manner with time. The polarity of transport through any given type of tissue increases exponentially with increasing lengths of tissue traversed, suggesting that the polarity

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 ...

Mathematical Modelling of Auxin Transport in Plant Tissues: Flux Meets Signalling and Growth. [PDF]
Bull Math Biol, 2020 Plant hormone auxin has critical roles in plant growth, dependent on its heterogeneous distribution in plant tissues. Exactly how auxin transport and developmental processes such as growth coordinate to achieve the precise patterns of auxin observed ...

A Role for Calcium in Auxin Transport [PDF]
Plant Physiology, 1973 The basipetal transport of the auxin, indoleacetic acid, in sunflower stem sections is markedly suppressed by washing the tissue in ethylenediaminetetraacetate, and transport is restored by subsequent application of calcium solutions. The ethylenediaminetetraacetate treatment is shown to result in the removal of substantial amounts of calcium from the ...

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 ...

Role of the Arabidopsis PIN6 auxin transporter in auxin homeostasis and auxin-mediated development.
PLoS ONE, 2013 Plant-specific PIN-formed (PIN) efflux transporters for the plant hormone auxin are required for tissue-specific directional auxin transport and cellular auxin homeostasis.

Auxin transport model for leaf venation. [PDF]
Proc Math Phys Eng Sci, 2019 The plant hormone auxin controls many aspects of the development of plants. One striking dynamical feature is the self-organization of leaf venation patterns which is driven by high levels of auxin within vein cells. The auxin transport is mediated by specialized membrane-localized proteins.
