Polar Auxin Transport and Asymmetric Auxin Distribution [PDF]

The Arabidopsis Book, 2007
Introduction: 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 first phytohormone to be discovered was auxin, a substance that

Simulation of Organ Patterning on the Floral Meristem Using a Polar Auxin Transport Model [PDF]

, 2012
An intriguing phenomenon in plant development is the timing and positioning of lateral organ initiation, which is a fundamental aspect of plant architecture.

Repression of the auxin response pathway increases Arabidopsis susceptibility to necrotrophic fungi [PDF]

, 2008
In plants, resistance to necrotrophic pathogens depends on the interplay between different hormone systems, such as those regulated by salicylic acid (SA), jasmonic acid (JA), ethylene, and abscisic acid.

The Arabidopsis ATP-BINDING CASSETTE Transporter ABCB21 Regulates Auxin Levels in Cotyledons, the Root Pericycle, and Leaves

Frontiers in Plant Science, 2019
The phytohormone auxin plays significant roles in regulating plant growth and development. In Arabidopsis, a subset of ATP-BINDING CASSETTE subfamily B (ABCB) transporters participate in polar movement of auxin by exclusion from and prevention of ...

Hypocotyl transcriptome reveals auxin regulation of growth-promoting genes through GA-dependent and -independent pathways. [PDF]

PLoS ONE, 2012
Many processes critical to plant growth and development are regulated by the hormone auxin. Auxin responses are initiated through activation of a transcriptional response mediated by the TIR1/AFB family of F-box protein auxin receptors as well as the AUX/

A Receptor for Auxin [PDF]

The Plant Cell, 2005
A long-sought hormone receptor has been found. Two recent Nature articles reveal that the F-box protein TRANSPORT INHIBITOR RESPONSE1 (TIR1) binds auxin and responds to the phytohormone even when heterologously expressed in animal systems ([Dharmasiri et al., 2005a][1]; [Kepinski and Leyser, 2005 ...

Modeling Auxin Signaling in Roots: Auxin Computations

Cold Spring Harbor Perspectives in Biology, 2021
Auxin signaling and patterning is an inherently complex process, involving polarized auxin transport, metabolism, and signaling, its effect on developmental zones, as well as growth rates, and the feedback between all these different aspects. This complexity has led to an important role for computational modeling in unraveling the multifactorial roles ...

Auxin Homeostasis in Arabidopsis Ovules Is Anther-Dependent at Maturation and Changes Dynamically upon Fertilization

Frontiers in Plant Science, 2017
The plant hormone auxin is a vital component for plant reproduction as it regulates the development of both male and female reproductive organs, including ovules and gynoecia.

phot1 inhibition of ABCB19 primes lateral auxin fluxes in the shoot apex required for phototropism [PDF]

, 2011
It is well accepted that lateral redistribution of the phytohormone auxin underlies the bending of plant organs towards light. In monocots, photoreception occurs at the shoot tip above the region of differential growth.

Evolution and structural diversification of PILS putative auxin carriers in plants

Frontiers in Plant Science, 2012
The phytohormone auxin contributes to virtually every aspect of the plant development. The spatiotemporal distribution of auxin depends on a complex interplay between auxin metabolism and intercellular auxin transport.
