Lipid production control factor for oleaginous yeast

A method comprising performing on a yeast at least one selected from the group consisting of the following (1) and (2) to increase or decrease lipid production capacity of the yeast:

• (1) increasing or decreasing the expression of a 115694 gene in the yeast, and
• (2) expressing, in the yeast, the 115694 gene having a mutation in a region between the transmembrane domain and the nuclear localization signal,
• wherein:
• the 115694 gene is a gene encoding a protein consisting of an amino acid sequence having at least 95% identity with an amino acid sequence represented by SEQ ID NO:
• 1,
• the mutation is at least one mutation selected from the group consisting of M1108T, F1115S, and K1119E of the amino acid sequence represented by SEQ ID NO:
• 1, and
• the yeast belongs to the genus Lipomyces.
