Double strand break (DSB) repair pathways in plants and their application in genome engineering

Code: 9781801461368
Natalja Beying, Carla Schmidt and Holger Puchta, Karlsruhe Institute of Technology, Germany

Chapter synopsis: In genome engineering, after targeted induction of double strand breaks (DSBs) researchers take advantage of the organisms’ own repair mechanisms to induce different kinds of sequence changes into the genome. Therefore, understanding of the underlying mechanisms is essential. This chapter will review in detail the two main pathways of DSB repair in plant cells, non-homologous end joining (NHEJ) and homologous recombination (HR) and sum up what we have learned over the last decades about them. We summarize the different models that have been proposed and set these into relation with the molecular outcomes of different classes of DSB repair. Moreover, we describe the factors that have been identified to be involved in these pathways. Applying this knowledge of DSB repair should help us to improve the efficiency of different types of genome engineering in plants.
