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.

This study identifies CYP735A3 and CYP735A4 as enzymes required for tZ-type cytokinin biosynthesis in rice, showing their role in growth promotion of both roots and shoots.

This study shows photosynthesis-dependent activation of PM H+-ATPase in Arabidopsis leaves enhances nitrate uptake, linking photosynthesis and nitrogen metabolism.

This study shows that reducing cytokinin perception in roots increases shoot growth by altering trans-zeatin distribution in Arabidopsis.

Oryza longistaminata regulates ammonium acquisition and use in response to spatial nitrogen heterogeneity through inter-ramet communication.

The paper shows that phosphate starvation response precedes abscisic acid response in plants under mild drought, using field and controlled experiments.

This study investigates the molecular and developmental mechanisms of heterophylly in Callitriche palustris, revealing hormonal and transcriptional differences from other amphibious plants.

The paper identifies genes under purifying selection and species-specific expression signatures in PTI responses across Brassicaceae species using comparative transcriptomics.

This study shows DNA damage in Arabidopsis roots increases cytokinin synthesis, which suppresses auxin transport and reduces root growth.

This study identifies plastidic glutamine synthetase 2 (GLN2) as the primary cause of ammonium toxicity in Arabidopsis thaliana by inducing shoot acidity.

The paper identifies a maize mutant with altered leaf patterning due to increased cytokinin signaling from a gain-of-function mutation in the cytokinin receptor ZmHK1.
