Compositions and methods are provided for genome modification at a target site in the genome of a fungal cell. Aspects of methods and compositions are drawn to a guide polynucleotide/Cas endonuclease system for promoting insertion of a donor DNA at a desired target site in a fungal host cell genome.

Disclosed are transformed cells comprising one or more genetic modifications that affect the lipid content of the cell, e.g., by increasing the concentration of oleic acid in the cell relative to an unmodified cell of the same type. Also disclosed are methods for modifying the lipid content of a cell by increasing the activity of one or more proteins in the cell and/or by decreasing the activity of one or more proteins in the same cell.

The present invention relates to the field of fungal biotechnology, more particularly to genetic engineering methods for the production of carotenoids in fungal hosts selected from Rhodospordium and Rhodotorula genera.

The present disclosure provides a sophorolipid composition that can be used for inducing protein expression in a fermentation host. The sophorolipid composition described herein can be prepared from a natural sophorolipid mixture. Acid treatment of the natural sophorolipid mixture results in a mixture of monoacetylated, deacetylated, and/or diacetylated sophorolipids. The chemically modified sophorolipid composition, or isolated components of the chemically modified sophorolipid composition, can be used as inducers for protein production in filamentous fungi.
