Abstract

In vivo footprinting experiments have been used to analyze the binding of trans-acting regulatory factors in the 5′ flanking region upstream of the alcohol dehydrogenase ( Adh) gene from Arabidopsis thaliana. Protein-DNA interactions were detected by dimethyl sulfate footprinting and genomic sequencing, using an A. thaliana cell suspension culture that constitutively expressed the Adh gene. Several distinct footprinting domains have been characterized, and the potential effects of the corresponding trans-acting factors have been inferred from a comparison with data from the maize alcohol dehydrogenase-1 ( Adh1) gene. One binding site is similar in sequence to one of the anaerobic response elements (ARE) of the maize gene, which has also been shown to bind to a trans-acting factor. Several of the remaining binding sites apparently represent a class of elements sharing the sequence 5′-GTGG-3′ within their footprint. Comparisons with maize Adh1 in vivo protein interactions reveal that the elements of Adh promoter structure are highly conserved, but the relative and absolute positions of the elements are variable.
