Plant viral intergenic DNA sequence repeats with transcription enhancing activity.

Although the number of elements tested is relatively small and, so far, only representative of promoters from the geminiviruses and nanoviruses classes of plant viruses, there is a clear trend suggesting that directly repeated elements (including those containing small internal palindromic sequences) are more likely to play significant roles in the enhancement of transcription than inverted repeats.
