Solanum tuberosum Aux/IAA family: new members and characterization of StIAA1 interacting proteins
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
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 ...
Auxin and Cellular Elongation
(American Society Of Plant Biologist, 2016-03)
Auxin is a crucial growth regulator in plants. However, a comprehensive understanding of how auxin induces cell expansion is perplexing, because auxin acts in a concentration- and cell type-dependent manner. Consequently, ...
Multiple links between shade avoidance and auxin networks
(Oxford University Press, 2018-01)
Auxin has emerged as a key player in the adjustment of plant morphology to the challenge imposed by variable environmental conditions. Shade-Avoidance responses, including the promotion of stem and petiole growth, leaf ...
Auxin import and local Auxin Biosynthesis are required for Mitotic Divisions, Cell Expansion and Cell Specification during female Gametophyte development in Arabidopsis Thaliana
(Public Library Of Science, 2015-05)
The female gametophyte of flowering plants, called the embryo sac, develops from a haploid cell named the functional megaspore, which is specified after meiosis by the diploid sporophyte. In Arabidopsis, the functional ...
Tomato fruit development in the auxin-resistant dgt mutant is induced by pollination but not by auxin treatment
In tomato (Solanum lycopersicum Mill.), auxin is believed to play a pivotal role in controlling fruit-set and early ovary growth. In this paper we investigated the effect of the reduced auxin sensitivity exhibited by the ...
Differential auxin transport and accumulation in the stem base lead to profuse adventitious root primordia formation in the aerial roots (aer) mutant of tomato (Solanum lycopersicum L.)
(Elsevier Gmbh, 2017-02)
The aerial roots (aer) mutant of tomato is characterized by a profuse and precocious formation of adven-titious root primordia along the stem. We demonstrated that auxin is involved in the aer phenotype butruled out higher ...
Nitric oxide is required for the auxin-induced activation of NADPH-dependent thioredoxin reductase and protein denitrosylation during root growth responses in arabidopsis
(Oxford University Press, 2015-06)
Background and Aims: Auxin is the main phytohormone controlling root development in plants. This study uses pharmacological and genetic approaches to examine the role of auxin and nitric oxide (NO) in the activation of ...
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 ...
SYNTHESIS OF HYDROGELS CONTAINING INDOLBUTYRIC ACID AS ROOTING AUXIN
