Gene-Edited Poinsettias Branch Naturally, Do Not Need Bacterial Infection and Pruning

Researchers at Aarhus University, in collaboration with Graff Breeding A/S, have developed a gene-edited poinsettia that branches naturally without the need for bacterial infection or manual pruning. Traditionally, the plant's bushy shape has been achieved using a specific bacterium, which creates challenges for growers and requires a lot of labor.

In the project called StarQuality supported by Innovation Fund Denmark, the researchers identified and modified a single gene that controls branching. This breakthrough allows the poinsettias to grow bushy on their own. Using gene editing technology, they succeeded in developing plants where a single genetic modification allows the poinsettia to branch naturally. The new technology has already resulted in a patent application and a licensing agreement, paving the way for commercial production.

This innovation could significantly reduce labor costs for growers and offer consumers a more sustainably grown, bacteria-free plant. The researchers believe the same techniques could be applied to other ornamental and even food crops in the future.
