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.

Cytokinin treatments affect the apical-basal patterning of the Arabidopsis gynoecium and resemble the effects of polar auxin transport inhibition

Frontiers in Plant Science, 2014
The apical-basal axis of the Arabidopsis gynoecium is established early during development and is divided into four elements from the bottom to the top: the gynophore, the ovary, the style, and the stigma. Currently, it is proposed that the hormone auxin

A mechanistic framework for auxin dependent Arabidopsis root hair elongation to low external phosphate [PDF]

, 2018
Phosphate (P) is an essential macronutrient for plant growth. Roots employ adaptive mechanisms to forage for P in soil. Root hair elongation is particularly important since P is immobile.

Aintegumenta and Aintegumenta-Like6 regulate auxin-mediated flower development in Arabidopsis

BMC Research Notes, 2011
Background Two related genes encoding AP2/ERF-type transcription factors, AINTEGUMENTA (ANT) and AINTEGUMENTA-LIKE6 (AIL6), are important regulators of floral growth and patterning in Arabidopsis.

Strigolactones spatially influence lateral root development through the cytokinin signaling network [PDF]

, 2015
Strigolactones are important rhizosphere signals that act as phytohormones and have multiple functions, including modulation of lateral root (LR) development.

Lipochitin Oligosaccharides from Rhizobium leguminosarum bv. viciae Reduce Auxin Transport Capacity in Vicia sativa subsp. nigra Roots

Molecular Plant-Microbe Interactions, 1999
Induction of the formation of root nodule primordia in legume roots by symbiotic rhizobia is probably preceded by a change in plant hormone physiology. We used a Vicia sativa (vetch) split root system to study the effect of inoculation with rhizobia or ...

Root system architecture from coupling cell shape to auxin transport. [PDF]

PLoS Biology, 2008
Lateral organ position along roots and shoots largely determines plant architecture, and depends on auxin distribution patterns. Determination of the underlying patterning mechanisms has hitherto been complicated because they operate during growth and ...

The Diverse Salt-Stress Response of Arabidopsis ctr1-1 and ein2-1 Ethylene Signaling Mutants Is Linked to Altered Root Auxin Homeostasis

Plants, 2021
We explored the interplay between ethylene signals and the auxin pool in roots exposed to high salinity using Arabidopsisthaliana wild-type plants (Col-0), and the ethylene-signaling mutants ctr1-1 (constitutive) and ein2-1 (insensitive).

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.

Measuring Auxin Transport Capacity in Seedling Roots of Medicago truncatula

Bio-Protocol, 2016
Measurement of auxin transport capacity provides quantitative data on the physiological machinery involved in auxin transport within plants. This technique is easy to perform and gives quick results. Radiolabelled auxin (indole-3-acetic-acid) is fed into
