    Abstract

    CDeT27-45 is a lea-like gene from the resurrection plant Craterostigma plantagineum (Scrophulariaceae) which is strongly expressed in vegetative tissues in response to dehydration or treatment with abscisic acid (ABA). Expression of the gene is correlated with the acquisition of desiccation tolerance Nuclear proteins bind to a 29-bp cis-regulatory region of the promoter which is essential for transcriptional activation of the CDeT27-45 gene by ABA. Using a yeast one-hybrid screen, the cDNA clone CpR18 was isolated, which encodes a protein with specific binding activity for the cis-regulatory element in the CDeT27-45 promoter. The protein contains an acidic region, a SAP-domain, a zinc finger of the C
