Abstract:

Crop improvement by domestication and traditional breeding often results in fitness penalties and loss of genetic diversity, which greatly threatens crop production and food security under the challenging global climate. De novo domestication has been proposed as a novel strategy for crop breeding. By combining multi-omics, genome editing and synthetic biology approaches, domestication of wild or semi-wild plant species can be accelerated by rapidly introducing desirable traits without causing an associated drag on their inherent traits. In this review, we summarize the history of crop domestication, emphasize the urgency for breeding strategy innovation, and discuss recent progress of de novo crop domestication.

Key words: de novo crop design, fast domestication, wild species, genome editing
