    • The present invention relates to mutants of a parent Trichoderma strain, comprising a polynucleotide encoding a polypeptide and one or more (several) genes selected from the group consisting of a first subtilisin-like serine protease gene, a first aspartic protease gene, a trypsin-like serine protease gene, a second subtilisin-like serine protease gene, and a second aspartic protease gene, wherein the one or more (several) genes are modified rendering the mutant strain deficient in the production of one or more (several) enzymes selected from the group consisting of a first subtilisin-like serine protease, a first aspartic protease, a trypsin-like serine protease, a second subtilisin-like serine protease, and a second aspartic protease, respectively, compared to the parent Trichoderma strain when cultivated under identical conditions. The present invention also relates to methods of producing a polypeptide in such mutants and methods for producing such mutants.

    • The present invention relates to methods for reducing or eliminating the expression of a target gene in a filamentous fungal strain, comprising: (a) inserting into the genome of the strain a double-stranded transcribable nucleic acid construct comprising a first nucleotide sequence comprising a promoter operably linked to a homologous coding region of the target gene and a second nucleotide sequence comprising the homologous coding region, or a portion thereof, of the target gene, wherein first and second nucleotide sequences are complementary to each other and the second nucleotide sequence is in reverse orientation relative to the first nucleotide sequence; and (b) inducing production of an interfering RNA encoded by the double-stranded transcribable nucleic acid construct by cultivating the under conditions conducive for production of the interfering RNA; wherein the interfering RNA interacts with RNA transcripts of the target gene to reduce or eliminate expression of the target gene.
    • 本发明涉及用于减少或消除丝状真菌菌株中靶基因表达的方法,其包括:(a)在菌株的基因组中插入双链可转录核酸构建体,其包含第一核苷酸序列,其包含启动子 可操作地连接到靶基因的同源编码区和包含靶基因的同源编码区或其部分的第二核苷酸序列,其中第一和第二核苷酸序列彼此互补,第二个核苷酸序列在 相对于第一核苷酸序列的反向取向; 和(b)通过培养有利于产生干扰RNA的条件,诱导由双链可转录核酸构建体编码的干扰RNA的产生; 其中所述干扰RNA与所述靶基因的RNA转录物相互作用以减少或消除所述靶基因的表达。
