Pleiotropy and epistasis in auxin signaling networks
… responses. Targeting the engineering of hormone signaling networks holds promise for enhancing plant health, crop productivity, and vigor. However, these networks are intricate, featuring negative feedback loops, extensive interconnections between pathways, pleiotropy, and overlapping gene …

Decoding the Transcriptional Specificity of Auxin Signaling: A Synthetic Biology Approach
Auxin is a central regulator of nearly all aspects of plant growth, development, and environmental response. Despite its broad roles, the mechanisms by which a single hormone elicits such diverse and context-specific transcriptional responses remain unclear. These responses are primarily mediated …

Atvps34, the Arabidopsis Phosphotidylinositol 3-Kinase, Its Functions in ABA and Auxin Signaling Pathways and the Molecular Basis for Salinity Stress Tolerance in Extremophile Thellungiella Halophila
Thellungiella halophila, a close relative of Arabidopsis thaliana, is a halophyte that can survive in sea water. Microarray transcript profiling and intensity analysis, quantitative RT-PCR, and metabolite profiles revealed shared and divergent responses to salt stress in the two species. Sixty …

Understanding and Engineering Chemically Activated Ubiquitin Ligases for High-throughput Detection, Quantification, and Control of Molecules in Yeast
… animals, and humans. Certain fungi produce auxin or indole-3-acetic acid (IAA), a crucial plant growth hormone that influences various aspects of plant growth and defense mechanisms. Conversely, pathogenic fungi can produce auxin and manipulate auxin signaling in their host plant to promote …

Regulace zakládání hlíz u bramboru: role auxinu
… to stolons as a protein. BEL5/POTH1 and StP6A signaling pathways seem to overlap. Phytohormones also play an important signaling role, i.a. auxins. During tuber initiation, IAA levels in stolon tissues increase. PIN transporters are likely to be involved in the redistribution of auxin in the …

CONTROL OF CELL DIVISION AND DIFFERENTIATION IN THE ARABIDOPSIS ROOT - STUDIES ON THE AUXIN RESISTAN 3 (AXR3) GENE
… crucial for plant development. In Arabidopsis, auxin signaling mediated by its repressors AUX/IAA proteins, plays a key role in mediating root development and growth. However, it is still not well understood how AUX/IAA proteins coordinates cell division and cell differentiation in the …

Characterization of the IBR5-PAD1 Interaction in Arabidopsis Auxin Response
… phosphatase, plays an important role in the auxin signaling pathway. Previous studies suggest that IBR5 negatively regulates Aux/IAA repressor protein degradation. This research identifies and characterizes a novel interaction between IBR5 and PAD1, a subunit of the 20S core of the …

Characterization of SCF Ubiquitin-Ligase Subunits in Arabidopsis
… Response (TIR1), is a member of a family of five Auxin-signaling F-box proteins (AFBs) and has been shown to act as the receptor for auxin binding and activation of the SCF TIR1 complex, leading to targeted protein degradation events involved in auxin perception. We provide evidence for …

Characterizing the Expression Pattern of miR167-Regulated ZmArf3 and ZmArf30 in Maize Inflorescences
… controls. miR167 targets mRNAs that encode the auxin response factors (ARF), ARF3 and ARF30 in maize. ARFs function as part of the auxin-signaling network to regulate transcription of auxin sensitive genes. The plant hormone auxin is necessary for virtually all aspects of plant growth, including …

Auxin and the nodule
… to characterise the role of the plant hormone auxin in the development of nitrogen-fixing, indeterminate legume nodules. More specifically we want to know the timing of, and the processes responsible for, the auxin signaling induction detected upon inoculation of the root of Medicago truncatula …

Synthetic Auxin Engineering: Building a Biofoundry Platform
… approach – has facilitated engineering of the auxin signaling pathway in a synthetic yeast system. Auxin is a phytohormone involved in nearly every aspect of plant growth and development, and this striking versatility designates it as a target for biotechnology development and a candidate for …

Forward and reverse genetic approaches to investigate cellulose biosynthesis in Physcomitrium patens
… two point mutations in CULLIN1 (CUL1) and AUXIN/INDOLE-3-ACETIC ACID INDUCED (Aux/IAA) which both are involved in auxin signaling pathways. The mutants were also cross-resistant to synthetic auxin 2,4-D. It is predicted that indaziflam affects plant growth and development and impacted the …

Attachment of fibrous materials in nature and surgical repair
… of the cell wall and its mediation by pH and auxin signaling are key factors in these responses. Analysis of a sutured connection to a viscoelastic substratum then revealed that the effects of viscoelastic relaxation can be harnessed to improve soft/hard reattachment via discrete connections …

Molecular and physiological characterisation of selected DOF transcription factors in the model plant Arabidopsis thaliana
… that both genes work in the plant hormone auxin signaling pathway and have an impact on distal cell differentiation. Altered levels of gene expression lead to changes in auxin distribution, abnormal cell division patterns and altered root growth orientation. DOF3.1 and DOF5.2 share a …

Quantitative Trait Loci Analysis of Low Temperature Responses in Grapevine F2 Population
… candidate genes associated with calcium signaling, ethylene signaling, ABA signaling, cellular metabolism and dehydration response were found underlying the 1.5 LOD interval of these QTLs. The bud break phenology was studied at three chilling periods to identify bud break related QTL. Bud …
