This study identifies GORK as the K+ channel mediating flg22-induced K+ efflux and stomatal closure during PTI in Arabidopsis.

The paper shows that MCA1 mechanosensitive channels mediate rapid inter-root signaling in Arabidopsis following mechanical injury.

This study shows that under salt stress, quinoa guard cells become transcriptionally insensitive to ABA but maintain K+ uptake channel activity, reducing transpiration and enhancing CO2 sensitivity.

The paper introduces two free LabView-based software tools for ion flux measurements using Scanning Ion-Selective Electrodes (SISE).

The paper shows that cytosolic Ca2+ acts as a universal signal for rapid root growth regulation in response to various stimuli.

The paper uses optogenetics to show that Ca2+ signals regulate early auxin signaling in Arabidopsis roots, affecting growth and transcriptional responses.

The paper investigates the structural gating mechanisms of YnaI, showing it opens via radial relocation of sensor paddles and pore shortening, contrasting with MscS's tilt-based mechanism.

The paper solves the cryo-EM structure of Arabidopsis GORK, revealing symmetry reduction driven by ANK dimerization, which regulates K+ channel activity in guard cells.

This study identifies impaired cell wall biomechanics as the cause of delayed trap closure in the Venus flytrap mutant DYSCALCULIA, linking mechanosensing and Ca2+ signaling to trap kinetics.

This study shows date palm roots increase osmotic strength with drought by accumulating sugars over minerals, while leaves undergo membrane remodeling and ROS scavenging to prevent oxidative damage.
