title: Targeted Gene Disruption by Ectopic Induction of DNA Elimination in Tetrahymena.
abstract: Tetrahymena is a useful eukaryotic model for biochemistry and molecular cell biology studies. We previously demonstrated that targeted ectopic DNA elimination, also called co-Deletion (coDel), can be induced by the introduction of an internal eliminated sequence (IES)-target DNA chimeric construct. In this study, we demonstrate that coDel occurs at most of the loci tested and can be used for the production of somatic gene KO strains. We also showed that coDel at two loci can be simultaneously induced by a single transformation; thus, coDel can be used to disrupt multiple gene loci in a single cell. Therefore, coDel is a useful tool for functional genetics in Tetrahymena and further extends the usefulness of this model organism.
