Interconversion of fast and slow gating modes of GCAC1, a Guard Cell Anion Channel

Abstract

For guard-cell protoplasts of Vicia faba L. we elucidated whether the slow (S-type) and rapid (R-type) activating anion channels represent different gating modes of GCAC1, the Guard Cell Anion Channel. In the whole-cell configuration of the patch-clamp technique, GCAC1 was activated in a Ca2+- and nucleotide-dependent manner. Cell-free outside-out membrane… (More)
