Organ functions are ultimately linked to the developmental mechanisms regulating their formation. Thus, we are interested in defining the morphological and molecular signatures regulating brace root development. We anticipate that manipulating these developmental mechanisms can be used to optimize brace root function. To define the mechanisms of development, we are taking molecular development approaches to define the stages of brace root initiation, emergence and growth. We are complimenting this work with genetics to identify the regions of the genome associated with brace root phenotypes and function.

Defining the mechanisms of brace root development.
Brace roots are a type of adventitious root, meaning they are roots developing from non-root tissues. There is limited work to define the mechanisms of adventitious root development. In this project, we are working to define the morphological and molecular regulation of brace root initiation and emergence. Specific work includes defining the role of the phytohormone auxin in brace root initiation.

Genetic analysis of brace root phenotypes & function.
In collaboration with Dr. Brian Dilkes, we are mapping the genetic basis of brace root phenotypes, and their contribution to biomechanics in maize and sorghum.
