Intraspecies polymorphisms of Kluyveromyces marxianus strains from Yaghnob valley.

abstract：:A cloning cassette, carrying a modified amino-glycoside resistance gene (neo) from transposon Tn5 was constructed. Three restriction sites internal to the neo gene were eliminated by in vitro mutagenesis, allowing their use in designing new cloning vectors. The original, suboptimal transcription promoter was replaced ...
