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 ...
Low auxin sensitivity of diageotropica tomato mutant alters nitrogen deficiency response
(2020-01-01)
Plant responses to nitrogen supply are dependent on auxin signaling, but much still remains to be elucidated regarding N deficiency in tomato. Thus, the objective of this work was to evaluate how low auxin sensitivity ...
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 ...
Rewiring of auxin signaling under persistent shade
(National Academy of Sciences, 2018-05)
Light cues from neighboring vegetation rapidly initiate plant shade-avoidance responses. Despite our detailed knowledge of the early steps of this response, the molecular events under prolonged shade are largely unclear. ...
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, ...
ABA biosynthesis genes are down regulated while auxin and cytokinin biosynthesis genes are up-regulated during the release of grapevine buds from endodormancy
(Springer, 2017)
Auxin–cytokinin (CK) interactions have been
extensively studied in the control of bud outgrowth in herbaceous
plants. However, in temperate woody plants where
the meristem of dormant buds can be repressed by either
exogenous ...
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 ...
Origin of TAA genes in charophytes: New insights into the controversy over the origin of auxin biosynthesis
(Frontiers Media S.A., 2017-09)
There is a current controversy around the origin of auxin biosynthesis genes in plants. Auxin is one of the most important plant hormone and its major biosynthesis pathway implies the tryptophan aminotransferase (TAA) and ...
