Abstract

Arabidopsis ZIM is a putative transcription factor containing an atypical GATA-type zinc-finger motif. Transcriptional activation by ZIM was tested using a transient GAL4 fusion assay and measuring the expression of a luciferase reporter in tobacco BY-2 cells. ZIM functioned as a transcriptional activator, and the transactivation domain was found to occur in its N-terminal acidic region.
