Protein-binding sequences that may regulate organ-preferential transcription of zrp2, a Zea mays root-preferential gene

Abstract: In this study, D A-protein interactions of a one kilobase region proximal to the transcription start site of the zrp2 (Zea mays root-preferential 2) gene promoter was analyzed. The intent of this research was to identify regions of the promoter and D Aprotein interactions, that are responsible for root-preferential transcription. In vitro run-on transcription assays had re ealed dramatically higher levels of transcription in 3-d-old roots than in 5-d-old leaves (Held, 1993). Interactions between regions of the… Show more

“…It may be that this region contains an enhancer-like element that activates transcription in the root. DNA gel-shift assays have revealed root proteins capable of binding the zrp2 DNA in this region [43].…”

“…The position and size of other introns that might be present within the zrp2 gene is currently unknown. About 2.6 kb of the 4.7 kb upstream region of the zrp2 gene was sequenced [19,43] . A putative TATA box is present 22 bp upstream of the mapped transcription start site [19].…”
