Abstract
Food security is a very important issue to meet the demands of continuously increasing population. To fulfil the global demand, current improvement rate is not enough. There is a dire need of improving food crops to enhance production and deal with changing climate, reduction in existing water resources and less arable land. Traditional approaches are also being used for improvement in agricultural productivity, but the dawn of genome editing technologies has transformed the plant research. In this chapter, we have discussed different genome editing tools including some latest tools like prime editor which can be used for food security. Various examples from different food crops have been discussed where crop traits like yield, quality, nutrition, biotic and abiotic stress resistance were improved using genome editing tools. The prospects of these technologies have also been addressed including factors affecting release of genome-edited crops in the field.
