Construction of mutant strains
WebThe target protein is secreted in these nine mutant strains; if the production of target protein in a mutant strain is higher than that in strain PD8, the corresponding protease is regarded as favorable. Accordingly, the optimal protease-deficient host is constructed through inactivating the unfavorable proteases.

Complementation refers to a relationship between two different strains of an organism which both have homozygous recessive mutations that produce the same phenotype (for example, a change in wing structure in flies) but which do not reside on the same (homologous) gene. These strains are true breeding for their … WebA central tool for gene function analysis is the construction mutant strains. This can be done conveniently in A. gossypii using PCR-based tools. The deletion of essential genes can be performed since initial transformants are sheltered in a heterokaryotic mycelium, which contains nuclei with both wild type and mutant alleles.
