Title
Apoplastic pH During Low-oxygen Stress in Barley
HUBERT H. FELLE Annals of Botany 2006. doi:10.1093/aob/mcl193
Other claims from this paper (5)
- Intervention effect Barley leaves alkalinized the apoplast and depolarized membranes under oxygen stress.
- Observation The leaf responses persisted under anoxia but were transient under hypoxia.
- Intervention effect Root flooding during the first two hours did not change leaf apoplastic pH.
- Intervention effect Anoxia decreased proton motive force by over 70 %.
- Mechanism Loss of proton motive force under anoxia impairs proton-driven transport.
