KIN7 Kinase Regulates the Vacuolar TPK1 K Channel during Stomatal Closure.

Stomata are leaf pores that regulate CO uptake and evapotranspirational water loss. By controlling CO uptake, stomata impact on photosynthesis and dry matter accumulation. The regulation of evapotranspiration is equally important because it impacts on nutrient accumulation and leaf cooling and enables the plant to limit water loss during drought [1].
