Abstract excerpt

At least four genes encoding plasma membrane inward K+ channels (K(in) channels) are expressed in Arabidopsis guard cells. A double mutant plant was engineered by disruption of a major K(in) channel gene and expression of a dominant negative channel construct. Using the patch-clamp technique reve...
