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.
- Root anatomical phenes predict root penetration ability and biomechanical properties in maize
- Phene synergism between root hairs and basal root growth angle for phosphorus acquisition in common bean
- Reduced frequency of lateral root branching improves N capture from low N soils in maize
- Edaphic control of plant response to elevated CO2 in Festuca arundinaceae
- Evolution of maize (Zea mays L.) root architectural and anatomical phenes over the past 100 years corresponds to increased tolerance of nitrogen stress
