The past decade has witnessed unprecedented development in genome engineering, a process that enables targeted modification of genomes. The identification of sequence-specific nucleases such as zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs) and the CRISPR/Cas system, in particular, has led to precise and efficient introduction of genetic variations into genomes of various organisms. Since the CRISPR/Cas system is highly versatile, cost-effective and much superior to ZFNs and TALENs, its widespread adoption by the research community has been inevitable. In plants, a number of studies have shown that CRISPR/Cas could be a potential tool in basic research where insertion, deletion and/or substitution in the genetic sequence could help answer fundamental questions about plant processes, and in applied research these technologies could help build or reverse-engineer plant systems to make them more useful. In this review article, we summarize technologies for precise editing of genomes with a special focus on the CRISPR/Cas system, highlight the latest developments in the CRISPR/Cas system and discuss the challenges and prospects in using the system for plant biology research.
