Guanylate cyclase activity of TIR1/AFB auxin receptors mediates rapid auxin responses

The paper shows TIR1/AFB auxin receptors have both adenylate and guanylate cyclase activities, mediating transcriptional reprogramming and rapid Ca2+-dependent growth responses.

Single-cell transcriptomic analysis of pea shoot development and cell-type-specific responses to boron deficiency

This study uses single-cell RNA sequencing to analyze pea shoot development and cell-type-specific responses to boron deficiency, revealing differential gene expression and developmental impacts.

Potassium homeostasis and signaling as a determinant of Echinacea species tolerance to salinity stress

The study assesses K+ retention and salinity stress tolerance in four Echinacea species, finding higher K+ efflux in E. pallida and E. sanguinea under NaCl and ROS conditions.

Isotope-based visualization of element distribution in phloem provides functional evidence for the operation of SOS1 Na+/H+ exchangers in mature zones of Arabidopsis root

The paper uses radioisotope imaging and ion flux measurements to show that Na+ efflux via SOS1 occurs in mature root zones, not just the root apex, in Arabidopsis.

Boron Supply Restores Aluminum-Blocked Auxin Transport by Modulation PIN2 Trafficking in the Arabidopsis Roots

This study shows boron alleviates aluminum toxicity in Arabidopsis roots by restoring PIN2 endocytosis and auxin transport, reversing auxin depletion in the elongation zone.

Computational modeling and quantitative cell physiology reveal central parameters for the brassinosteroid-regulated early cell physiological processes linked to elongation growth of the Arabidopsis root

The paper uses computational modeling and quantitative cell physiology to identify key parameters and components involved in brassinosteroid-regulated cell elongation in Arabidopsis root epidermis.

Zoom in on Ca2+ pattern and ion flux dynamics to decode spatial and temporal regulation of cotton fiber growth

The paper uses confocal imaging and ion flux measurements to show that cotton fiber growth is diffusive, not tip growth, and responds to H2O2 with increased ion efflux.

The AFB1 auxin receptor controls rapid auxin signaling and root growth through membrane depolarization in Arabidopsis thaliana

This study shows that AFB1 auxin receptor mediates auxin-induced membrane depolarization and rapid root growth inhibition in Arabidopsis thaliana.
