Root Phenomics Laboratory

The Root Phenomics Laboratory develops new technologies to measure many root traits and applies these technologies to learn about how plant roots forage in soil. The overall research agenda makes use of the functional phenomics pipeline for root trait discovery, linking traits to genetic regions, and understanding root trait function using experiments and simulation modelling.

Root traits of interest include root number, branching, nutrient uptake ability, and respiration. Focal plant species include forage and bioenergy crops, especially winter wheat and switchgrass, but with collaborations to investigate model species such as Arabidopsis, Brachypodium and Medicago.

Methods have been developed for image-based root phenotyping using RhizoVision Explorer, using infrared gas analyzers for respiration, screening uptake of several nutrients simultaneously, and use of stable isotopes. These methods are used to both understand phenotypic diversity and the ecology of root, soil, and microbe interactions. The carbon cycle and allocation among plant tissues and root types is a major conceptual integrator in our work.
