Endogenous gene editing

Biotechnology Genetically modified crops have supporters and opponents, but how can these views be reconciled to improve food security? This problem is particularly acute for middle-income countries that need to export crops to maintain their economy as well as provide for their expanding population. In a Perspective, Zaidi et al. discuss the promise of new plant breeding technologies to edit endogenous genes in crop plants. These innovations will ideally improve food security and avoid barriers to use and implementation that face traditional genetically modified crops. Science , this issue p.
