Potassium (K+) is an essential macronutrient in plants and a lack of K+ significantly reduces
the potential for plant growth and development. By contrast, sodium (Na+), while beneficial …

Highlights•K+ channels and transporters are involved in diverse physiological
processes.•Plants can sense external K+ deficiency and generate low-K+ signals in plant …

Potassium uptake is vital for plant growth but in saline soils sodium competes with
potassium for uptake across the plasma membrane of plant cells. This can result in high …

As one of the most important mineral nutrient elements, potassium (K+) participates in many
plant physiological processes and determines the yield and quality of crop production. In this …

The two alkali cations Na+ and K+ have similar relative abundances in the earth crust but
display very different distributions in the biosphere. In all living organisms, K+ is the major …

Potassium (K+) is an essential nutrient and the most abundant cation in plants, whereas the
closely related ion sodium (Na+) is toxic to most plants at high millimolar concentrations. K+ …

Background Salinity is a global issue threatening agricultural production systems across the
globe. While the major focus of plant salinity stress tolerance research has been on sodium …

Potassium (K+) and nitrogen (N) are essential nutrients, and their absorption and distribution
within the plant must be coordinated for optimal growth and development. Potassium is …

Potassium (K) is an integral part of plant nutrition, playing essential roles in plant growth and
development. Despite its abundance in soils, the limitedly available form of K ion (K+) for …

When exposed to salt, every plant takes up Na+ from the environment. Once in the symplast,
Na+ is distributed within cells and between different tissues and organs. There it can help to …
