pubmed:abstractText
The two auxin biosynthesis genes, aux1 and aux2 of Agrobacterium rhizogenes strain A4, are located on opposite DNA strands with a short integenic region (394 bp) between their coding sequences. A functional analysis of this divergent promoter is presented. The transcription initiation sites of the two aux genes were determined and regions important for promoter activity were identified by deletion and transient expression analyses in tobacco protoplasts. The promoter activity of the aux intergenic region was demonstrated. A strong enhancer element contained within an 84 bp promoter fragment was identified. Far upstream regions were shown to have negative effects on the promoter activity of the short intergenic region. Interactions between positive elements in the intergenic region and negative effects of the upstream sequences may be the basis of strict control of the auxin biosynthesis necessary for the induction and maintenance of hairy root growth.
