Fig. 8From: A novel transcriptional repressor specifically regulates xylanase gene 1 in Trichoderma reeseiDetermination of the precise binding motif of XTR1 via DNase I footprinting analysis. The promoter fragment Pxyn1 (− 321 ~ − 217 bp) was used as the probe and its sequence was shown, wherein the nucleotide sequence protected by recombinant XTR1-DBD was indicated in redBack to article page
