Ion changes and signaling in important crops under salt stress

What is it about?

Salinity is a worldwide problem that is increasing with the ongoing climate changes. This review explains how Na+ and Cl- are taken up in plants under salinity, how the plant is supposed to sense Na+ and starts a cascade of reactions in order to protect itself against these toxic ions. Calcium is an important signaling messenger together with changes in pH and potassium. Calcium-concentration changes takes place in the cell cytosol, and also in cell walls, nucleus and cell organelles, and the calcium waves are propagated through the whole plant tissue.

Why is it important?

For the development of salt-tolerant crops it is important to get knowledge and understanding on the mechanisms resistant plants have to counteract salt stress.
