A new winter-rotation oilseed crop has been generated from a freeze-tolerant wild field pennycress by de novo domestication, reducing its glucosinolate and erucic acid contents, as well as its weediness, without a growth and yield penalty. Commercialization has resulted in a low-carbon-intensity intermediate crop, demonstrating a great potential for de novo domestication to create a new crop rotation paradigm for the optimized utilization of agricultural resources.
