The Drs. Mary L. and Robert L. Powelson Endowment Fund to support research, extension and outreach, and/or teaching programs in plant pathology conducted by assistant professors or similar early career state-funded faculty (instructor, professor of practice).

Mike Behrenfeld and Colleagues:  A paper published in Nature Geoscience (Annual boom–bust cycles of polar phytoplankton biomass revealed by space-based lidar) prompted a joint news release from OSU and NASA's Langley Research Center entitled "Space Laser Reveals Boom-and-Bust Cycle of Polar Ocean Plants".  The manuscript is about using a satellite lidar to study polar plankton ecosystems.  "This is first demonstration of using such a satellite system to study these ecosystems and the study describes the processes controlling the annual boom-bust cycles of the plankton and looks at how ecosystem processes and ice cover changes are driving trends in polar plankton stocks.  The work is building toward a new era in satellite oceanography where lidar systems, coupled with advanced ocean color sensors, build toward a 3-dimensional reconstruction of global ocean ecosystems."

Brett Tyler and Colleagues: A paper published in "Science" (A paralogous decoy protects Phytophthora sojae apoplastic effector PsXEG1 from a host inhibitor) prompted a news release from OSU entitled "Virulent pathogen uses a genetic decoy to foil host's immune defenses". This was a collaborative project funded by the Chinese Government and the USDA National Institute of Food and Agriculture.  The discovery of a mechanism that may explain why Phytophthora are such devastating pathogens to crops and ecosystems could "open new approaches to controlling a wide diversity of destructive plant pathogens...".
