Polar auxin transport modulates early leaf flattening. [PDF]
Proc Natl Acad Sci U S A, 2022 The flattened leaf form is an important adaptation for efficient photosynthesis, and the developmental process of flattened leaves has been intensively studied. Classic microsurgery studies in potato and tomato suggest that the shoot apical meristem (SAM) communicates with the leaf primordia to promote leaf blade formation.

Polar auxin transport: an early invention. [PDF]
J Exp Bot, 2012 In higher plants, cell-to-cell polar auxin transport (PAT) of the phytohormone auxin, indole-3-acetic acid (IAA), generates maxima and minima that direct growth and development. Although IAA is present in all plant phyla, PAT has only been detected in land plants, the earliest being the Bryophytes.

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

Inhibition of Polar Auxin Transport by Ethylene [PDF]
Plant Physiology, 1967 Applied ethylene influences the growth of etiolated pea stem sections cut from untreated plants, but has no effect on (14)C-indoleacetic acid uptake, polar transport or destruction. However, the capacity of the polar auxin transport system is markedly reduced in sections cut from plants grown in ethylene, while the velocity of auxin transport is ...

Cell Polarity Signaling: Focus on Polar Auxin Transport [PDF]
Molecular Plant, 2008 Polar auxin transport, which is required for the formation of auxin gradients and directional auxin flows that are critical for plant pattern formation, morphogenesis, and directional growth response to vectorial cues, is mediated by polarized sub-cellular distribution of PIN-FORMED Proteins (PINs, auxin efflux carriers), AUX1/AUX1-like proteins (auxin

Auxin Activity of Substituted Benzoic Acids and Their Effect on Polar Auxin Transport [PDF]
Plant Physiology, 1966 Six dichloro-, 3 trichloro-, 2 triiodo-, and 3 heterosubstituted benzoic acids (amiben, dinoben, dicamba), and N-1-naphthylphthalamic acid have been tested for effects on growth and on polar auxin transport. Growth activity with and without kinetin was measured by effects on fresh and dry weights of 30-day cultures of fresh tobacco pith.

Cytokinins and polar transport of auxin in axillary pea buds [PDF]
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010 The influence of cytokinin on auxin transport during release of axillary buds from apical dominance was studied. Expression of auxin-carrier coding genes PsAUX1 (AUXIN RESISTANT 1) and PsPIN1 (PIN-FORMED 1) was explored in axillary buds of the 2nd node ...

Cell polarity and patterning by PIN trafficking through early endosomal compartments in Arabidopsis thaliana. [PDF]
PLoS Genetics, 2013 PIN-FORMED (PIN) proteins localize asymmetrically at the plasma membrane and mediate intercellular polar transport of the plant hormone auxin that is crucial for a multitude of developmental processes in plants.

Mathematical Model of Polar Auxin Transport [PDF]
Plant Physiology, 1966 Polar auxin transport can be simulated by a model which achieves polarity through the preferential secretion of more auxin from the lower end than from the upper end of each cell. Solution of the model using a computer provides a possible explanation of the differences between the polarity expressed by different tissues and the differences between ...

Melatonin regulates root meristem by repressing auxin synthesis and polar auxin transport in Arabidopsis [PDF]
Frontiers in Plant Science, 2016 Melatonin (N-acetyl-5-methoxytryptamine) plays important roles in regulating both biotic and abiotic stress tolerance, biological rhythms, plant growth and development.
