The overall research focus of the Roots Lab at Penn State is understanding the genetic, physiological, and ecological basis of plant adaptation to infertile soils.
Since most soils on earth suffer from one or more nutritional problems, this subject is of considerable importance for two of the great challenges confronting humanity: how to sustainably support over 7 billion people, and how to deal with global environmental change. More about the Roots Lab ...
We welcome prospective graduate students and collaborators interested in novel, multidisciplinary research that addresses real world issues.
Our work involves a number of students and colleagues at Penn State, and collaborators from other institutions. Dr. Kathleen Brown and Dr. Jonathan Lynch are close collaborators on virtually all aspects of the research.
- Image-based high-throughput field phenotyping of crop roots
- Root traits for improving nitrogen acquisition efficiency
- Field phenotyping of soybean roots for drought stress tolerance
- Root cortical aerenchyma enhances nitrogen acquisition from low nitrogen soils in maize (Zea mays L.)
- The optimal lateral root branching density for maize depends on nitrogen and phosphorus availability
