The paper examines how rhizosphere chemistry and bacterial communities respond to environmental stress gradients in the Atacama Desert, identifying metabolic biomarkers and their ecological implications.

The paper identifies common biochemical strategies across phylogenetically diverse Atacama Desert plant species adapted to extreme conditions.

The paper identifies molecular elements and signaling pathways involved in the repression of NRT2 transporters and root nitrate uptake in Arabidopsis in response to nitrate.

The paper identifies a molecular mechanism involving FER, ROP2, and TORC that controls root hair elongation under low temperature and nitrogen deficiency in Arabidopsis thaliana.

This study shows that Arabidopsis thaliana can benefit from interaction with Ensifer meliloti under nitrogen deficiency, completing its life cycle through bacterial nitrogen fixation.

This study identifies nitrate-induced phosphoproteomic changes in Arabidopsis roots, revealing PIN2 phosphorylation as critical for root system architecture regulation.

The paper investigates how nitrogen availability modulates root growth by fine-tuning polar auxin transport through post-translational modifications of PIN2 and presents a computational model to simulate these processes.

This study identifies TGA2 as essential for UV-B stress tolerance in Arabidopsis by activating antioxidant GSTU genes to control oxidative stress.

The paper compares transcriptomic and metabolic profiles of two table grape cultivars with different berry skin colors, identifying differences in flavonoid and primary metabolite composition and gene expression.

The paper identifies three transcription factors regulating NRT2.4 and NRT2.5 in response to N/C signals using a systems biology approach.
