Vanadate sensitive ATPase and phosphatase-activity in guard-cell protoplasts of Commelina
Phosphatase activity was measured in extracts of guard cell protoplasts of <em>Commelina communis</em> L. using the artificial substrate p-nitrophenylphosphate. A pH optimum of 5.8 to 6.3 was determined. Ammonium molybdate (Ol mol m−3) and sodium vanadate (1–0 mol m−3) gave almost comple...
