Dec 20, 2023 · The molecule auxin triggers fast and specific protein phosphorylation changes in land plants and algae. This ancient and widespread response is mediated by conserved B4 RAF-like kinases that connect rapid signaling to cellular auxin responses such as the acceleration of cytoplasmic streaming.

Auxin promotes cell division and meristem maintenance and also plays an important role in the establishment of cellular patterning. Plant development thus integrates the regulation of cell proliferation and growth with further cell expansion and differentiation.

5 days ago · A synthetic-biology-driven approach deciphers the ARF-dependent transcriptional code and its contribution to specificity in gene expression in Arabidopsis, providing key insights into how the auxin developmental signal triggers …

May 13, 2018 · An auxin is a plant hormone derived from the amino acid tryptophan. An auxin may be one of many molecules, but all auxin molecules are involved in some sort of cellular regulation.

Aug 21, 2021 · Auxins are plant hormones that play a central role in controlling plant growth and development across different environmental conditions. Even at low concentrations, auxins can regulate gene expression through specific transcription factors and proteins that are modulated to environmental responses …

Jan 5, 2024 · Auxin is a central hormone regulating plant growth and development, but the cellular sites and molecular mechanisms of auxin perception and signaling remain incompletely understood for decades.

Apr 29, 2020 · In this review, we focus on rapid auxin effects, their relationship to H + -ATPase activation and other transporters, and dependence on TIR1/AFB signaling. We also discuss how some observations, such as near-instantaneous effects on ion transport and root growth, do not fit into a single, comprehensive explanation of how auxin controls cell ...

In this review, we focus on rapid auxin effects, their relationship to H + -ATPase activation and other transporters, and dependence on TIR1/AFB signaling.

5 days ago · However, the molecular basis underlying its function during root development in these plant groups remains poorly understood. In this review, we summarize the current progress in our understanding of auxin-mediated root initiation, patterning, and branching in vascular non-seed plants while highlighting outstanding key questions.

Auxin-inducible synthetic promoters were expressed differentially in planta showing at single-cell resolution how this bi-layer code patterns transcriptional responses to auxin.
