Rapid, Futile K(+) Cycling and Pool-Size Dynamics Define Low-Affinity Potassium Transport in Barley
Using the short-lived radiotracer (42)K(+), we present a comprehensive subcellular flux analysis of low-affinity K(+) transport in plants. We overturn the paradigm of cytosolic K(+) pool-size homeostasis and demonstrate that low-affinity K(+) transport is characterized by futile cycling of K(+) at t...
