Control of guard cell aperture by protein kinase CIPK23
Plant Science Research WeeklyGuard cells are responsible for the opening and closing of stomata through changes in osmotic content and turgor pressure. These changes occur in response to activation or inactivation of ion transport proteins that are in turn regulated by protein kinase and phosphatase networks. The kinase network…
Plant PIEZO homologs modulate vacuole morphology during tip growth (Science)
Plant Science Research WeeklyThe ability to perceive and respond to mechanical stimuli and forces, such as gravity or touch, is an extremely well conserved property that is key for proper cellular function. This ability is fueled by mechanosensitive ion channels activated by mechanical disturbances in the membrane, which leads to…
