Expression of an Arabidopsis potassium channel gene in guard cells.

Abstract

The Arabidopsis thaliana KAT1 cDNA encodes a voltage-gated inward-rectifying K+ channel. A KAT1 genomic DNA clone was isolated and sequenced, and a 5' promoter and coding sequences containing eight introns were identified. Reporter gene analysis of transgenic plants containing the KAT1 promoter fused to bacterial beta-glucuronidase showed robust beta-glucuronidase activity primarily in guard cells.
