Abstract
Nucleic acid fragments having activities to prominently promote expression of structural genes located downstream thereof are disclosed. The nucleic acid fragment according to the present invention is an isolated nucleic acid fragment having the nucleotide sequence shown in SEQ ID NO: 1 in Sequence Listing or an isolated nucleic acid fragment (excluding the nucleic acid having the nucleotide sequence shown in SEQ ID NO: 3 in Sequence Listing) having the same nucleotide sequence as shown in SEQ ID NO: 1 except that one or a plurality of nucleotides are substituted or deleted, or except that one or a plurality of nucleotides are inserted or added, which has an activity to promote expression of a structural gene located downstream of said nucleic acid fragment.
