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 β-glucuronidase showed robust β-glucuronidase activity primarily in guard cells.
