Abstract

Na+ has a detrimental effect on the growth of most plants belonging to glycophytes. Although the mechanisms for Na+ exclusion from the upper shoot have been intensively investigated, the sites of Na+ retrieval and loading, and the rate of Na+ retranslocation under continuous Na+ presence have not been clear. In this study, we employed a non-invasive imaging technique using 22Na with a fine spatiotemporal resolution and demonstrated the movement of Na+ in roots.
