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

This study shows that LBD transcription factors repress local and systemic nitrogen responses in Arabidopsis through distinct pathways, enhancing nitrate uptake and N-related gene expression in their absence.

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

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.

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

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.

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.

This study shows that brassinosteroids (BRs) function as reproductive hormones in Arabidopsis, regulating gene expression in both male and female reproductive tissues during fertilization.

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.

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.

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

The paper shows that STOP1 dominates Arabidopsis ammonium tolerance over NRT1.1, with STOP1 directly activating NRT1.1 transcription and regulating common target genes.

This study identifies how the endophytic fungus Serendipita indica promotes Arabidopsis growth by altering auxin transport and conjugation through GH3 genes and PIN2 expression.

This study investigates the nitrate-independent role of NRT1.1 in Arabidopsis under high ammonium conditions, finding that its plasma membrane localization affects ammonium tolerance through gene expression changes.

The paper uses genome resources from Setaria viridis to identify loci associated with climate response, seed shattering, and leaf angle, and validates a novel domestication gene.
