These structures activate by using a proton pump to expel hydrogen ions, creating an electrical potential which causes the uptake of potassium ions.
It has been observed that the toxin coronatine when secreted from certain species of bacteria impairs the operation of these structures, preventing their response to further pathogens. These structures activate by using a proton pump to expel hydrogen ions, creating an electrical potential which causes the uptake of potassium ions. This in turn results in the uptake of water into these cells, increasing their turgor pressure and causing them to separate from their neighbor. In CAM plants, these cells only activate at night to reduce water loss through transpiration. FTP, name these sclerenchyma cells present on plant leaves that also regulate carbon dioxide uptake by opening and closing the stomata that they flank.
