Systematic transient assays of promoter activities for leaf-specific genes identified by gene-expression profiling with cDNA microarrays in Arabidopsis thaliana

J Biosci Bioeng. 2004;98(2):140-3. doi: 10.1016/S1389-1723(04)70257-1.


We identified 85 genes highly expressed in leaves using an Arabidopsis cDNA microarray. A vector, pRAB5, was designed to allow cloning and assaying of the promoters. Fifty-one promoters from the selected genes were cloned and then assayed using a microprojectile bombardment and dual luciferase reporter assay system. This system allowed efficient systematic assays of promoter activity.
