Fig. 6From: Stable and transient transformation, and a promoter assay in the selective lignin-degrading fungus, Ceriporiopsis subvermisporaSchematic representation of stable and transient transformation. Introduced recombinant hph plasmids confer hygromycin resistance by direction of its promoter sequence. Transient transformants may express hph extrachromosomally and lose the plasmid during repeated transfer on the fresh screening platesBack to article page
