Engineering key agronomic traits such as yield and stress tolerance is essential to mitigate the effects of climate change and enhance food security for the growing world population. Moreover, applying the design-build-test-learn cycle of synthetic biology in plants would enable the engineering of plants for traits of value and transform our ability to answer questions and understand plant behavior. Plants can be adopted as cheap, scalable, eco-friendly biofactories for various synthetic biology applications, including the production of key biologics and other pharmaceuticals. In addition, genome editing technologies have enabled the production of engineered crop varieties indistinguishable from conventional varieties, thereby simplifying the regulatory landscape and potentially improving customer acceptance. All of these diverse applications require robust methods for the delivery of genetic material, including nucleic acids, functional genetic circuits for synthetic biology, and genome editing reagents, into plant cells. Therefore, establishing an efficient genotype-and species-independent DNA delivery method will transform our ability to engineer genomes and harness plants for a myriad of applications.
