    • The present invention relates to methods for expression screening of filamentous fungal transformants, comprising: (a) isolating single colony transformants of a DNA library introduced into E. coli; (b) preparing DNA from each of the single colony E. coli transformants; (c) introducing a sample of each of the DNA preparations of step (b) into separate suspensions of protoplasts of a filamentous fungus to obtain transformants thereof, wherein each transformant contains one or more copies of an individual polynucleotide from the DNA library; (d) growing the individual filamentous fungal transformants of step (c) on selective growth medium, thereby permitting growth of the filamentous fungal transformants, while suppressing growth of untransformed filamentous fungi; and (e) measuring activity or a property of each polypeptide encoded by the individual polynucleotides.
    • 本发明涉及丝状真菌转化体的表达筛选方法,其包括:(a)分离导入大肠杆菌的DNA文库的单个菌落转化体; (b)从每个单个菌落的大肠杆菌转化体制备DNA; (c)将步骤(b)的每种DNA制剂的样品引入到丝状真菌的原生质体的分离悬浮液中以获得其转化体,其中每个转化体含有来自DNA文库的单个多核苷酸的一个或多个拷贝; (d)在选择性生长培养基上生长步骤(c)的单个丝状真菌转化体,从而允许丝状真菌转化体生长,同时抑制未转化的丝状真菌的生长; 和(e)测量由各个多核苷酸编码的每种多肽的活性或性质。

    • 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。
