We describe five new plasmid vectors derived from pBR322 that carry theNeurospora crassa β-tubulin gene conferring resistance to benomyl. The benomyl resistance gene has been modified to eliminate an internalEcoRI site to facilitate the cloning ofEcoRI restriction fragments. These plasmids allow rapid subcloning of fragments from one replicon to another without insert fragment purification due to the presence of different drug resistance markers (resistance to kanamycin, tetracycline, or chloramphenicol) carried on the plasmids. These vectors will allow rapid transformation ofN. crassa and other filamentous fungi to allow phenotypic characterization of subcloned fragments.
