The molecular core of transcriptome responses to abiotic stress in plants: a machine learning-driven meta-analysis

The paper identifies a core set of stress-related genes in plants using a machine learning-driven meta-analysis and provides a validated database for multi-stress resilience.

Primary multistep phosphorelay activation comprises both cytokinin and abiotic stress responses in Brassicaceae

The paper identifies Brassica homologs of Arabidopsis type-A response regulators, shows evolutionary selective pressure on RRAs, and demonstrates cytokinin dependency in cold-induced RRA upregulation.

Cytokinins control secondary cell wall formation in the inflorescence stem of Arabidopsis

This study shows cytokinins suppress premature secondary cell wall formation in Arabidopsis by downregulating NAC transcription factors, affecting tracheary element size and conductivity.

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.

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.

Expansin-controlled cell wall stiffness regulates root growth in Arabidopsis

This study identifies expansin localization and function in regulating cell wall stiffness and root growth in Arabidopsis.

Mutually opposing activity of PIN7 splicing isoforms is required for auxin-mediated tropic responses in Arabidopsis thaliana

The paper shows that PIN7 splicing isoforms PIN7a and PIN7b have opposing activities essential for auxin-mediated tropic responses in Arabidopsis thaliana.

Cell-surface receptors enable perception of extracellular cytokinins

The paper shows that cytokinin perception occurs via plasma membrane receptors in root cells, challenging previous assumptions about receptor localization and highlighting the role of spatial distribution in signaling.

Cellulose biosynthesis inhibition reduces cell cycle activity in a nitrate reductase- and cytokinin-dependent manner

The paper investigates how cellulose biosynthesis inhibition affects cell cycle activity in Arabidopsis thaliana seedlings, showing a nitrate reductase- and cytokinin-dependent response.
