Other claims from this paper (9)
- Observation All tested anions permeated slow channels in the stated selectivity sequence.
- Intervention effect Cytosolic malate at 150 mM slowly downregulated slow anion channel currents.
- Association Single anion channel currents correlated with whole-cell currents.
- Observation Single channels confirmed high nitrate permeability relative to chloride.
- Observation Single-channel studies supported multiple conductance states.
- Mechanism Multiple channel conductance states suggested cooperativity.
- Mechanism Slow anion channels could mediate physiological chloride efflux rates.
- Observation Slow anion channels did not strongly discriminate among anions.
- Mechanism Slow anion channels may provide efficient anion efflux from guard cells.
