Establishing Dual-Color Super-Resolution sptPALM for Live-Cell Plasma Membrane Protein Tracking in Arabidopsis thaliana

The paper establishes dual-color sptPALM for tracking two plasma membrane proteins in Arabidopsis thaliana cells using optimized fluorescent proteins.

OneFlowTraX: A User-Friendly Software for Super-Resolution Analysis of Single-Molecule Dynamics and Nanoscale Organization

OneFlowTraX is a user-friendly software for analyzing single-molecule dynamics and nanoscale organization in living cells, offering automated localization, tracking, and clustering analysis.

In planta exploitation of leaf apoplastic compounds: a window of opportunity for spatiotemporal studies of apoplastic metabolites, hormones and physiology

This paper introduces a non-invasive method to extract leaf apoplastic solutes over time with high spatial resolution, revealing apoplastic abscisic acid gradients and kaempferol glycoside accumulation in response to salinity.

Cytokinins regulate spatially-specific ethylene production to control root growth in Arabidopsis

This study shows cytokinins regulate ethylene production in specific root regions, controlling root growth and apical meristem size in Arabidopsis through spatially distinct mechanisms.

A phospho-switch provided by LRR receptor-like kinase, ALK1/QSK1/KIN7, prioritizes ABCG36/PEN3/PDR8 transport toward defense

This study identifies a phospho-switch mechanism involving ALK1 and ABCG36 that prioritizes defense-related transport over growth in Arabidopsis.

PEP7 is a ligand for receptor kinase SIRK1 to regulate aquaporins and root growth

The paper identifies PEP7 as a ligand for the receptor kinase SIRK1, showing it regulates aquaporins and root growth through phosphorylation and water influx.

AHK5 mediates ETR1-initiated multistep phosphorelay in Arabidopsis

This study identifies AHK5 as a mediator of ETR1-initiated multistep phosphorelay in Arabidopsis, showing it transfers phosphate from ETR1 to AHPs without requiring its own HK activity.

Three-fluorophore FRET enables the analysis of ternary protein association in living plant cells

The paper uses three-fluorophore FRET and FLIM to show BRI1, BAK1, and RLP44 form a ternary complex in plant plasma membrane nanodomains, distinct from FLS2/BAK1 complexes.

Arabidopsis AZG2, an auxin induced putative cytokinin transporter, regulates lateral root emergence

This study identifies AtAZG2 as an auxin-induced cytokinin transporter in Arabidopsis that regulates lateral root emergence by modulating cytokinin signaling.

OBERON3 and SUPPRESSOR OF MAX2 1-LIKE proteins form a regulatory module specifying phloem identity

The paper identifies OBERON3 and SUPPRESSOR OF MAX2 1-LIKE proteins as a regulatory module that establishes phloem identity in Arabidopsis thaliana through chromatin remodeling and gene expression.

A novel mutant allele uncouples brassinosteroid-dependent and independent functions of BRI1

A novel BRI1 mutant uncouples BR signaling and RLP44 function, revealing distinct roles of BRI1 in vascular development and hormone response.

The striking flower-in-flower phenotype of Arabidopsis thaliana Nossen (No-0) is caused by a novel LEAFY allele

This paper identifies a novel LEAFY allele in Arabidopsis thaliana No-0 that causes a flower-in-flower phenotype due to disrupted DNA-binding function.
