Gibberellins modulate auxin responses during tomato (Solanum lycopersicum L.) fruit development
(Wiley Blackwell Publishing, Inc, 2019-04)
In tomato, auxin and gibberellins (GAs) interact with each other to drive fruit growth and development. While the role of auxin in directing GA biosynthesis and signal is already known, very little information has been ...
A spatially concerted epidermal auxin signaling framework steers the root hair foraging response under low nitrogen
(Cell Press, 2023-09-25)
As a major determinant of the nutrient-acquiring root surface, root hairs (RHs) provide a low-input strategy to enhance nutrient uptake. Although primary and lateral roots exhibit elongation responses under mild nitrogen ...
PATELLINS are regulators of auxin-mediated PIN1 relocation and plant development in Arabidopsis thaliana
(Company of Biologists, 2018)
Coordinated cell polarization in developing tissues is a recurrent theme in multicellular organisms. In plants, a directional distribution of the plant hormone auxin is at the core of many developmental programs. A feedback ...
Auxin and salicylic acid signalings counteract during the adaptive response to stress
(Taylor & Francis, 2011-03)
In a previous publication, we performed a phenotypic characterization of Arabidopsis auxin receptor mutants grown under oxidative and salt stresses. In particular, the double mutant for TIR1 and AFB2 receptors, tir1 afb2 ...
Solanum tuberosum Aux/IAA family: new members and characterization of StIAA1 interacting proteins
(Springer, 2010-06)
Auxin/indole-3-acetic acid (Aux/IAA) proteins are transcriptional repressors that regulate auxin-mediated gene expression by interacting with members of the auxin response factor (ARF) family. We previously identified the ...
Nitric oxide regulates auxin signaling through s-nitrosylation of the Arabidopsis Transport Inhibitor Response1 auxin receptor
(Wiley, 2012-05)
Previous studies have demonstrated that auxin (indole-3-acetic acid) and nitric oxide (NO) are plant growth regulators that coordinate several plant physiological responses determining root architecture. Nonetheless, the ...

(Company of Biologists Ltd, 2018)
© 2018. Published by The Company of Biologists Ltd. Coordinated cell polarization in developing tissues is a recurrent theme in multicellular organisms. In plants, a directional distribution of the plant hormone auxin is ...
Auxin signaling participates in the adaptative response against oxidative stress and salinity by interacting with redox metabolism in Arabidopsis
(Springer, 2010-07)
Auxin regulates gene expression through direct physical interaction with TIR1/AFB receptor proteins during different processes of growth and development in plants. Here we report the contribution of auxin signaling pathway ...
Regulation of auxin signaling: A key node of plant development and acclimation to stress
(Sociedade Brasileira de Bioquímica e Biologia Molecular, 2019)
Auxin has been implicated in developmental switches as well as in transient and dynamic cellular responses during acclimation to abiotic stress. The core components of the auxin signaling machinery mainly involves the F-box ...
DAO1 catalyzes temporal and tissue-specific oxidative inactivation of auxin in Arabidopsis thaliana
(2016-09-27)
Tight homeostatic regulation of the phytohormone auxin [indole-3-acetic acid (IAA)] is essential to plant growth. Auxin biosynthetic pathways and the processes that inactivate auxin by conjugation to amino acids and sugars ...
