Journal ArticleDOI
Immediate-early and delayed cytokinin response genes of Arabidopsis thaliana identified by genome-wide expression profiling reveal novel cytokinin-sensitive processes and suggest cytokinin action through transcriptional cascades.
TL;DR: A genome-wide view of changes in cytokinin-responsive transcript abundance of genes that might be functionally relevant for the many biological processes that are governed by cytokinins is presented.
Journal ArticleDOI
Two cytokinin receptors of Arabidopsis thaliana, CRE1/AHK4 and AHK3, differ in their ligand specificity in a bacterial assay.

TL;DR: Strains of Escherichia coli that express two different cytokinin receptors of Arabidopsis thaliana, CRE1/AHK4 and AHK3, were used to study the relative sensitivity of these receptors to various cytokinins, indicating that the diverse cytokinIn compounds might have specific functions in the numerous cytokin in-regulated processes.
Journal ArticleDOI
Biochemical characteristics and ligand-binding properties of Arabidopsis cytokinin receptor AHK3 compared to CRE1/AHK4 as revealed by a direct binding assay
TL;DR: The revealed properties of AHK3 suggest its specific function in root-to-shoot communication, and was pH dependent, and influenced by monovalent cations, while divalent cations at physiological concentrations had no significant effect.
Journal ArticleDOI
The Cytokinin Receptors of Arabidopsis Are Located Mainly to the Endoplasmic Reticulum
Klaas Wulfetange,Sergey N. Lomin,Georgy A. Romanov,Andrea Stolz,Alexander Heyl,Thomas Schmülling +5 more
TL;DR: A modified model for cytokinin signaling is proposed in this article, which predicts the perception of the cytokinins signal at the plasma membrane by membrane-located sensor histidine kinases.
Journal ArticleDOI
The specificity of cytokinin signalling in Arabidopsis thaliana is mediated by differing ligand affinities and expression profiles of the receptors
Andrea Stolz,Michael Riefler,Sergey N. Lomin,Katharina Achazi,Georgy A. Romanov,Thomas Schmülling +5 more
TL;DR: In this article, the authors explored which parameters contribute to signal specification of three membrane-located cytokinin receptors (AHK2, AHK3 and CRE1/AHK4), which are sensor histidine kinases containing a ligand-binding CHASE domain.
