TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: In the method (M2), the function of creA/cre-1 is reduced by overexpression of a dominant negative mutant or a protein inhibitor; the recombinant cell further exhibits reduced expression of at least one beta -mannosidase gene compared to the expression of the at least one beta -mannosidase genes in a corresponding non-recombinant cell; the recombinant cell further exhibits reduced expression of at least one phospholipase gene or phospholipase-like gene compared to the expression of at least one phospholipase gene or phospholipase-like gene in a corresponding non-recombinant cell; and gene expression is reduced by siRNA, antisense DNA, quelling, or meiotic silencing. Preferred Components: The beta -glucosidase genes are at least three (preferably at least four, especially at least seven) beta -glucosidase genes. The beta -glucosidase genes comprise NCU00130, NCU04952, and NCU08755. The beta -glucosidase gene encodes an intracellular beta -glucosidase, or extracellular beta -glucosidase. The beta -mannosidase gene is NCU00890. The phospholipase gene or phospholipase-like gene is NCU06650. The secreted protein is cellulose-induced protein, preferably cellulase, GH61 enzyme, cellobiose dehydrogenase, lactonase, carbohydrate esterase, a polysaccharide lyase, and/or cellulose binding domain-containing protein, especially cellulase. The secreted protein is encoded by a gene selected from NCU07340, NCU09680, NCU07898, NCU00762, NCU08760, NCU05057, NCU02240, NCU07190, NCU07898, NCU08760, NCU00206, NCU07143, NCU09491, NCU09664, NCU05598, NCU09764, and NCU05137. Preferred Cell: The mutant cell (C1) further comprises an inactivating mutation in a cre-1 gene in the cell. The mutant cell (C2) further comprises inactivating mutations in at least two beta -glucosidase genes, or at least one beta -mannosidase gene in the cell. The mutant cell (C1) or (C2) further comprises an inactivating mutation in at least one phospholipase gene or phospholipase-like gene in the cell, where the inactivating mutations are deletions. The recombinant cell (C3) further exhibits reduced expression of a cre-1 gene compared to the expression of the expression of the cre-1 gene in a corresponding non-recombinant cell. The recombinant cell (C4) further exhibits reduced expression of at least two beta -glucosidase genes compared to the expression of the at least two beta -glucosidase genes in a corresponding non-recombinant cell. The mutant cell further comprises an inactivating mutation in a cre-1 gene in the cell, where cellulosic biomass induces the cell to secrete higher levels of a protein than a corresponding cell lacking the mutation in the cre-1 gene; inactivating mutation in at least one beta -mannosidase gene in the cell, where cellulosic biomass induces the cell to secrete higher levels of a protein than a corresponding cell lacking the mutation in at least one beta -mannosidase gene; inactivating mutation in at least one phospholipase gene or phospholipase-like gene in the cell, where cellulosic biomass induces the cell to secrete higher levels of a protein than corresponding cell lacking the mutation in the phospholipase gene or phospholipase-like gene. The recombinant cell exhibits reduced expression of a cre-1 gene compared to the expression of the cre-1 gene in a corresponding non-recombinant cell, where the expression is reduced by siRNA, antisense DNA, quelling, or meiotic silencing, and cellulosic biomass induces the cell to secrete higher levels of a protein than the corresponding non-recombinant cell in which the expression of the cre-1 gene is not reduced. In the recombinant cell, the function of creA/cre-1 is reduced by overexpression of a dominant negative mutant or a protein inhibitor, where cellulosic biomass induces the cell to secrete higher levels of a protein than corresponding cell in which the dominant negative mutant is not overexpressed. The recombinant cell further exhibits reduced expression of at least one beta -mannosidase gene compared to the expression of the beta -mannosidase gene in a corresponding non-recombinant cell, where the expression is reduced by siRNA, antisense DNA, quelling, or meiotic silencing, and where cellulosic biomass induces the cell to secrete higher levels of a protein than the corresponding non-recombinant cell in which the expression of the least one beta -mannosidase gene is not reduced; reduced expression of at least one phospholipase gene or phospholipase-like gene compared to the expression of the phospholipase gene or phospholipase-like gene in a corresponding non-recombinant cell, where the expression is reduced by siRNA, antisense DNA, quelling, or meiotic silencing, where cellulosic biomass induces the cell to secrete higher levels of a protein than the corresponding non-recombinant cell in which the expression of the phospholipase gene or phospholipase-like gene is not reduced.
