Abstrakt: As an essential macronutrient, potassium (K + ) plays crucial roles in diverse physiological processes during plant growth and development. The K + concentration in soils is relatively low and fluctuating. Plants are able to perceive external K + changes and generate chemical and physical signals in plant cells. The signals can be transducted across the plasma membrane and into the cytosol, and eventually regulates the downstream targets, particularly K + channels and transporters. As a result, K + homeostasis in plant cells is modulated, which facilitates plant adaptation to K + deficient conditions. This minireview focuses on the latest research progress in the diverse functions of K + channels and transporters as well as their regulatory mechanisms in plant response to low-K + stress.
