The mechanisms of lateral root development from a parent root is an extremely well-studied process. What has received less attention is the development of roots from stems. These stem-borne roots can be found in a variety of plant species, from tropical mangroves to banyan trees to cultivated maize. Our lab focuses on the development of stem-borne roots in maize (brace roots) due to the vast molecular and biological resources available. Maize brace roots are ubiquitous across genotypes, but the mechanisms regulating their initiation are unknown. In this project, our goal is to define the morphological and molecular mechanisms associated with the initiation of brace roots in maize.
