From: Reverse genetics in Chlamydomonas: a platform for isolating insertional mutants
Distance from the inserted marker gene to the host genomic DNA | Stability of the maker primer binding sites on the integrated marker DNA | Risk of non-selectable insertions (partial plasmid sequences or incomplete marker genes) | |
---|---|---|---|
Plasmid-free marker DNA (Library 1) | Short (as short as few bp) for both borders of the marker DNA | Stable if placed within the marker gene coding sequence | Low1 |
Linearized entire plasmid marker DNA (Library 2) | Long (up to few kb) for at least one border of the marker DNA | Can be lost if placed close to the borders of the linearized vector | High2 |
