In experiments directed to develop a promoter trap strategy in Arabidopsis, using a Ds chimaeric element containing a promoterless beta-glucuronidase (GUS) gene, we identified a promoter in the 3' end region of the Ac transposable element. The promoter initiates most of the transcripts at coordinate 4250 in the Ac sequence and is oriented towards the internal part of the element. When fused to a promoterless GUS gene, the promoter allows transient expression in Arabidopsis leaves. After stable integration into the Arabidpsis genome, no GUS activity was observed in most of the transformed lines analysed. Only two of them exhibited different tissue-specific GUS expression. When a CaMV 35S promoter was introduced into the transformation vector, downstream to the reporter gene, a high level of GUS activity was observed in all the transformants. These results strongly suggest that the promoter is not normally expressed at a significant level in Arabidopsis transformed lines except when activated by neighbouring cis-acting enhancer elements. This opens an interesting possibility for using this promoter to develop 'enhancer trap' strategies in Arabidopsis. Since only one Ac transcript, initiating in the 5' end region of the element has been reported to date in maize, the putative biological function of the promoter remains an open question.
