Effect of Vanadate on Rhythmic Leaflet Movement in Albizzia Julibrissin1

Henrik Saxe a, Ruth L Satter a,2
PMCID: PMC543389  PMID: 16661080

Abstract

Vanadate (Na3VO4) selectively and reversibly affects the rhythmic movement of Albizzia julibrissin leaflets. Leaflets floated on 1 millimolar vanadate open at the same rate or more rapidly than controls, but closure is inhibited. After 6 to 24 hours incubation, the inhibition can be reversed by a 24-to 48-hour period on water or control buffer. Recovery is complete in light-dark cycles, and it is almost complete under free-running conditions (prolonged darkness). Leaflets floated on 10 millimolar vanadate do not open in darkness, but they open at a reduced rate in light. Concentrations of 100 micromolar or less are ineffective.
