Journal Article
Rasmussen, A., Vidoz, M. L., & Sparks, E. E. (2024). Stem-borne roots as a framework to study trans-organogenesis and uncover fundamental insights in developmental biology. Current Opinion in Plant Biology, 81, Article 102604. https://doi.org/10.1016/j.pbi.2024.102604

Plants have a remarkable ability to generate organs with a different identity to the parent organ, called “trans-organogenesis”. An example of trans-organogenesis is the formation of roots from stems (a type of adventitious root), which is the first...
