The physical maps of recombinant plasmids. a The pYX212-kan (empty vector). b, c The pYX212 with SPT15-Mu and TAF23-Mu, respectively. The genes are under the R-control of TPI promoter and terminator with EcoRI and SalI restriction sites for SPT15 and SalI and NheI restriction sites for TAF23; (Ampr) ampicillin resistance gene; (Kanr) Kanamycin resistance gene; (G418) resistance gene
