e0“The ΔΨ‐dependent uptake of Na + was similar in vesicles from roots of hexaploid (cv. Troy) and tetraploid (cv. Langdon) wheat differing in a K + /Na + discrimination trait, and was also unaffected by growth in 50 mol m −3 NaCl.”

Other claims from this paper (10)
- Method / resource Marker enzyme analysis confirmed vesicle purity and orientation.
- Intervention effect Negative membrane potential stimulated sodium uptake.
- Observation Vesicle sodium uptake had a Km of 34.8 ± 5.9 mol m 3.
- Observation Potential dependent sodium uptake was similar in Troy and Langdon roots.
- Intervention effect Calcium inhibition of sodium uptake was greater in hexaploid than tetraploid wheat.
- Observation The sodium proton antiport had a Km between 13 and 19 mol m −3.
- Intervention effect Salt growth increased antiport activity in hexaploid wheat roots.
- Observation Salt grown hexaploid roots had greater antiport activity than salt grown tetraploid roots.
- Observation Antiport activity was not increased in the Langdon 4D substitution line.
- Mechanism The authors conclude neither transport process explains 4D chromosome sodium potassium discrimination.
