Transformation and regeneration of DNA polymerase Θ mutant rice plants

Agrobacterium T‐DNA integration into the plant genome is essential for the process of transgenesis and is widely used for genome engineering. The importance of the non‐homologous end‐joining (NHEJ) protein DNA polymerase Θ, encoded by the PolQ gene, for T‐DNA integration is controversial, with some...

Sumario:Agrobacterium T‐DNA integration into the plant genome is essential for the process of transgenesis and is widely used for genome engineering. The importance of the non‐homologous end‐joining (NHEJ) protein DNA polymerase Θ, encoded by the PolQ gene, for T‐DNA integration is controversial, with some groups claiming it is essential whereas others claim T‐DNA integration in Arabidopsis and rice polQ mutant plant tissue. Because of pleiotropic effects of PolQ loss on plant development, scientists have previously had difficulty regenerating transgenic polQ mutant plants. We describe a protocol for regenerating transgenic polQ mutant rice plants using a sequential transformation method. This protocol may be applicable to other plant species.
