The present disclosure provides compositions and methods for gene editing. The disclosure also provides methods for removing extra-chromosomally replicating plasmids from competent cells.

The present disclosure provides compositions and methods for gene editing. The disclosure also provides methods for removing extra-chromosomally replicating plasmids from competent cells.

A method for producing a protein is provided. An objective protein is produced by culturing in a culture medium Talaromyces cellulolyticus having an objective protein-producing ability, which has been modified so that the activity of a Pep4 protein is reduced.

Provision of a modified promoter derived from a xylanase promoter. A modified promoter comprising a polynucleotide of Xyn3 promoter comprising a polynucleotide that comprises at least one polynucleotide of Xyn1 promoter cis-element or a complementary strand thereof in a region corresponding to the nucleotides at position 374 to 401 of SEQ ID NO:1. The polynucleotide of Xyn3 promoter consist of the following nucleotide sequences: the nucleotide sequence represented by SEQ ID NO:1; the nucleotide sequence represented by the nucleotides at position 350 to 1084 of SEQ ID NO:1; or a nucleotide sequence that has an identity of at least 90% therewith and that comprises the sequence represented by SEQ ID NO:2 in a region corresponding to the nucleotides at position 374 to 401 of SEQ ID NO:1. The polynucleotide of Xyn1 promoter cis-element consists of the nucleotide sequence represented by SEQ ID NO:4.
