Efficient scarless gene editing in Pichia pastoris via survival stress-based intramolecular homologous recombination.
To overcome low efficiency and/or genomic instability induced by DNA cleavage in current genome-editing approaches, a novel pop-in/pop-out-based editing system was developed for Pichia pastoris. An ingenious arrangement of components leads to a more efficient screening by permitting the only type of DNA recombination u...
