NOVEL AUXOTROPHIC FISSION YEAST

摘要

It is intended to provide an auxotrophic fission yeast wherein a novel auxotrophic marker gene has been mutated in a fission yeast (Schizosaccharomyces pombe). It is also intended to provide a vector to be used together with this auxotrophic fission yeast. An arginine or asparagine-requiring fission yeast is acquired and subjected to gene analysis. This auxotrophic fission yeast is formed by a mutation in fission yeast arg1⁺ gene (SPCC777.09c), fission yeast asn1⁺ gene (SPBC119.10) or fission yeast lys4⁺ gene (SPBC1105.02c). Thus, a vector usable with it can be constructed.
