The changing global conditions of food and feed availability for a growing world population on shrinking arable land are some of the main challenges for modern agriculture. In addition to this, global warming with the accompanying development of new pest and pathogens as well as quickly overcome resistances are immense challenges for agricultural efficiency. Conventional and molecular breeding, which are used today are versatile tools but laborious, time consuming and expensive. Therefore, these breeding tools seem not to be able to achieve the future goals alone. The development of GMO technology provided a much needed breakthrough to satisfy agricultural demands. Although this technology came into existence two decades ago, its adoption has been limited to just a few countries whereas in other countries regulatory frameworks prevent the further exploitation of this technology. The recent development of sequence specific nucleases as genome editing tools, e.g. ZFNs, TALENs, and particularly CRISPR/Cas9 or RGENs, for the first time enables the precise modulation of traits of interest with unprecedented control and efficiency.

In this Research Topic, authors should focus on next-generation genome edited crop plants and new methods for the production of genetically edited crop plants which are free of recombinant nucleic acids. The plants produced from direct delivery of these tools could become a technology to meet current and future agriculture demands in a sustainable way.

Current research themes include:
1. Next-generation genome editing techniques for crop improvement.
2. Focus on any genome editing technology which could result in plants without recombinant DNA.
3. Possible regulations and policies on genome edited crop plants.
4. Any improvements in genome editing tools to enhance control and accuracy for crop improvement.
5. Focus on different modes of direct delivery of genome editing tools to plant systems.


Keywords: Genome editing, ZFNs, TALENs, CRISPR/Cas9, RGENs
