It is intended to provide base sequences participating in the regulation of the expression of a promoter. It is also intended to modify a promoter based on the base sequence data to give a modified promoter having a high expressi on activity. Namely, a modified promoter constructed by inserting a first DNA fragment containing CCAATNNNNNN (a first base sequence) and a second DNA fragment containing CGGNNNNNNNNNGG (a second base sequence) into a promoter functioning in a fungus, wherein N stands for A (adenine), G (guanine), c (cytosine) or T (thymine).
