CO2-sensitive K+ channel traffic affects stomata and whole-plant water use.

Abstract excerpt

Stomata are pores at the leaf surface that facilitate CO2 entry for photosynthesis while controlling transpirational water loss. Stomatal movements are governed by reversible changes in turgor and cell volume, driven by the transport of osmotic solute across the membrane of guard cells surrounding the pore. Membrane transport depends on the activities of transporters and ion channels present at the membrane and...
