Polar auxin transport controls suspensor fate [PDF]

open access: yesPlant Signaling & Behavior, 2008
Polar auxin transport is critical for normal embryo development in angiosperms. It has been proposed that auxin accumulates dynamically at specific positions, which in early Arabidopsis embryos correlates with developmental decisions such as specification of the apical cell lineage, specification of the hypophysis, and differentiation of the two ...

Polar auxin transport: models and mechanisms [PDF]

open access: yesDevelopment, 2013
Spatial patterns of the hormone auxin are important drivers of plant development. The observed feedback between the active, directed transport that generates auxin patterns and the auxin distribution that influences transport orientation has rendered this a popular subject for modelling studies.

All Roads Lead to Auxin: Post-translational Regulation of Auxin Transport by Multiple Hormonal Pathways

open access: yesPlant 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 ...

Electrophysiological study of Arabidopsis ABCB4 and PIN2 auxin transporters: Evidence of auxin activation and interaction enhancing auxin selectivity

open access: yesPlant Direct, 2021
Polar auxin transport through plant tissue strictly requires polarly localized PIN proteins and uniformly distributed ABCB proteins. A functional synergy between the two types of membrane protein where their localizations overlap may create the degree of

Cell Polarity Signaling: Focus on Polar Auxin Transport [PDF]

open access: yesMolecular 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

A rho scaffold integrates the secretory system with feedback mechanisms in regulation of auxin distribution. [PDF]

open access: yesPLoS Biology, 2010
Development in multicellular organisms depends on the ability of individual cells to coordinate their behavior by means of small signaling molecules to form correctly patterned tissues.

Arabidopsis ROOT UVB SENSITIVE2/WEAK AUXIN RESPONSE1 Is Required for Polar Auxin Transport   [PDF]

open access: bronzeThe Plant Cell, 2010
Abstract Auxin is an essential phytohormone that regulates many aspects of plant development. To identify new genes that function in auxin signaling, we performed a genetic screen for Arabidopsis thaliana mutants with an alteration in the expression of the auxin-responsive reporter DR5rev:GFP (for green fluorescent protein).

Differential behavior within a grapevine cluster: decreased ethylene-related gene expression dependent on auxin transport is correlated with low abscission of first developed berries. [PDF]

open access: yesPLoS ONE, 2014
In grapevine, fruit abscission is known to occur within the first two to three weeks after flowering, but the reason why some berries in a cluster persist and others abscise is not yet understood.

Mathematical Model of Polar Auxin Transport [PDF]

open access: yesPlant 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 ...

Control of leaf vascular patterning by polar auxin transport [PDF]

open access: diamondGenes & Development, 2006
The formation of the leaf vascular pattern has fascinated biologists for centuries. In the early leaf primordium, complex networks of procambial cells emerge from homogeneous subepidermal tissue. The molecular nature of the underlying positional information is unknown, but various lines of evidence implicate gradually restricted transport routes of the
