Outline of Final Research Achievements |
It is being known that segmental aneuploidy plays an important role for industrial yeast strain to display useful traits. We have developed a news genome engineering technology to create segmental duplication of any desired region of chromosome in yeast. This technology designated PCDup for PCR-mediated chromosome segmental duplication was applied to construct a series of 62 strains harboring every 10 kb to 200 kb chromosomal region. 53 among 62 regions were successfully duplicated while other regions were not. Phenotypic analysis of 53 strains harboring segmental duplication revealed that some of the strains displayed industrially useful trains such as resistance to high temperature and acid environment. Since it has never been reported that over-expression of individual genes present on those regions causes such phenotype, we suggest that those phenotypes were likely due to simultaneous over-expression of some of genes present on those regions.
