| Research Abstract |
Using PCR-mediated chromosomal duplication and deletion technologies that we developed, we investigated whether segmental duplication or deletion of specific chromosomal regions improved industrially important phenotypes in Saccharomyces cerevisiae. Systematic analysis of segmental duplication and deletion of chromosomes revealed that alteration of copy number of specific chromosomal regions enhanced resistance against a variety of stresses including ethanol, high-temperature and acid stresses. These results indicate that the genome-engineering technologies provide an unique and useful tool not only for analyzing genome function but also for breeding of S. cerevisaie for efficient production of bioethanol or organic acids.
