Abstract:
... SUMMARY: Active removal of Na⁺ from the cytosol into the vacuole plays a critical role in salinity tissue tolerance, but another, often neglected component of this trait is Na⁺ retention in vacuoles. This retention is based on an efficient control of Na⁺‐permeable slow‐ and fast‐vacuolar channels that mediate the back‐leak of Na⁺ into cytosol and, if not regulated tightly, could result in a futile ...
