Current methods of biomolecule delivery to mature plants are limited due to the presence of plant cell wall, and are additionally hampered by low transfection efficiency, high toxicity of the transfection material, and host range limitation. For this reason, transfection is often limited to protoplast cultures where the cell wall is removed, and not to the mature whole plant. Unfortunately, protoplasts are not able to regenerate into fertile plants, causing these methods to have low practical applicability.
Researchers at the University of California have developed a method for delivery of genetic materials into mature plant cells within a fully-developed mature plant leaf, that is species-independent. This method utilizes a nano-sized delivery vehicle for targeted and passive transport of biomolecules into mature plants of any plant species. The delivery method is inexpensive, easy, and robust, and can transfer biomolecules into all phenotypes of any plant species with high efficiency and low toxicity.
