VLCFA-mediated inter-cell layer communication controls cellular pluripotency in Arabidopsis callus

The paper identifies VLCFA-mediated inter-cell layer communication as critical for pluripotency in Arabidopsis callus, independent of ATML1/PDF2 and cuticular wax synthesis.

Homoeo-alleles of wheat GNI2 fuel grain yields across input environments

This study identifies GNI2 homoeo-alleles in wheat that improve grain yield by 5-15% across high- and low-input environments.

Cytokinin receptor AHK3 influences leaf size by modulating trans-zeatin-type cytokinin levels in xylem

This study shows that AHK3 and CKX4 in roots regulate tZ-type cytokinin transport via xylem, affecting leaf size based on nitrogen availability.

The submergence-induced drastic morphological plasticity of root in the amphibious plant Callitriche palustris

This study identifies root morphological plasticity, termed heterorhizy, in the amphibious plant Callitriche palustris in response to submergence, revealing hormonal regulation and evolutionary conservation across species.

CONCERTED PLANT GROWTH AND DEFENSE THROUGH TARGETED PHYTOHORMONE CROSSTALK MODIFICATION

This study shows that modifying phytohormone crosstalk in Arabidopsis can enhance pathogen resistance and reproductive growth by reducing the growth-defense tradeoff.

Shoot nitrate status regulates Arabidopsis shoot growth and systemic transcriptional responses via shoot adenosine phosphate-isopentenyltransferase 3

This study shows shoot nitrate status regulates Arabidopsis growth and gene expression via shoot IPT3, which modulates CKs and transcriptomic responses in shoots and roots.

Large-scale single-cell profiling of stem cells uncovers redundant regulators of shoot development and yield trait variation

This study uses single-cell RNA-seq to identify stem cell regulators in maize and Arabidopsis, revealing genes linked to yield traits and shoot development.

MAX2-dependent signaling regulates the transition from 2D to 3D growth by suppressing cytokinin accumulation in Physcomitrium patens

Multiomics-based assessment of the impact of airflow on diverse plant callus cultures

The paper assesses airflow's impact on plant callus cultures using multiomics data from tobacco, rice, and bamboo species, revealing species-specific and within-species differences.

KAI2-dependent signaling controls vegetative reproduction in Marchantia polymorpha through activation of LOG-mediated cytokinin synthesis

This study identifies KAI2-dependent signaling as a regulator of vegetative reproduction in Marchantia polymorpha by activating MpLOG-mediated cytokinin synthesis, which in turn controls GCAM1 expression.

Arabidopsis ABCC4 encodes a cytokinin efflux transporter and is involved in root system development

This study identifies ABCC4 as a cytokinin efflux transporter in Arabidopsis, showing its role in root system development through regulation of cytokinin flow.
