Spatial variation in leaf potassium concentrations and its role in plant adaptation strategies

Potassium (K) is an essential element for regulating plant growth and physiological metabolism. However, little information is available on large-scale spatial variations in leaf potassium concentrations (LKC) in different plant species, the variations in LKC, and the mechanism underlying these vari...
