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 ...
Regulation Of Polar Auxin Transport In Grapevine Fruitlets (Vitis Vinifera L.) And The Proposed Role Of Auxin Homeostasis During Fruit Abscission
(2016)
Background: Indole-3-acetic acid (IAA), the most abundant auxin, is a growth promoter hormone involved in several developmental processes. Auxin homeostasis is very important to its function and this is achieved through ...
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 ...
Auxin-Environment Integration in Growth Responses to Forage for Resources
(Cold Spring Harbor Laboratory Press, 2021-04)
Plant fitness depends on the adequate morphological adjustment to the prevailing conditions of the environment. Therefore, plants sense environmental cues through their life cycle, including the presence of full darkness, ...
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, 2017-06)
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 but
ruled out ...
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 ...
Distribution of endogenous NO regulates early gravitropic response and PIN2 localization in arabidopsis roots
(Frontiers Media S.A., 2018-04-20)
High-resolution and automated image analysis of individual roots demonstrated that endogenous nitric oxide (NO) contribute significantly to gravitropism of Arabidopsis roots. Lowering of endogenous NO concentrations strongly ...
Role of auxin during intercellular infection of Discaria trinervis by Frankia
(Frontiers in Plant Science, 2014-08)
Nitrogen-fixing nodules induced by Frankia in the actinorhizal plant Discaria trinervis result from a primitive intercellular root invasion pathway that does not involve root hair deformation and infection threads. Here, ...
