August 12, 2012 Welcome Twenty-six years ago the Biennial Cellular and Molecular Biology of the Soybean Conference began here in Iowa. Since then it has travelled to many states and institutions across the U.S. During this time, our research community has watched soybean cellular and genetic resources expand from the use of biochemical markers to the completion of the soybean genome sequence. With these resources, soybean research has flourished, advancing critical research and promoting soybean crop improvement. We are pleased to welcome two plenary speakers. On Sunday evening, Dr. Carroll Vance will provide a historical perspective on soybean introduction and production in the U.S. In addition, Dr. Vance will highlight current and future research that leverages the soybean genome sequence to improve soybean yield and quality. During Monday morning’s plenary session, Dr. Jeff Doyle will address the adaptive success of legume polyploids and implications for crop improvement. The sessions that follow will include cutting edge research reports on pests and diseases, translation of genetic and genomic knowledge into soybean advancement, seed composition and nutrition, biotic interactions, functional genomics, genome structure and evolution and more. As you know, this conference would not have been possible without the generous support of our sponsors. In particular, we would like to acknowledge the organizers of the 2010 soybean conference, the Crop Science Department of North Carolina State University, for supporting the travel of minority and underrepresented students and post-docs. We are delighted by the number of people taking advantage of this opportunity. In addition, we would like to recognize Jennifer Vit with Iowa State University’s Conference Planning and Management for her invaluable help in organizing the conference. We are proud that the conference has returned to Iowa. We hope you enjoy the conference and your stay in Iowa. Sincerely, Randy C. Shoemaker, Chair Michelle Graham, Sponsorship Chair David Grant, Website Development and Abstract Chair Gustavo Macintosh, Travel Grant Chair Madan Bhattacharyya, Organizing Committee Steven Cannon, Organizing Committee Basil Nikolau, Organizing Committee Sponsor Acknowledgements Our sponsors have helped make SOY 2012 a conference that promotes the exchange of research and ideas between scientists from around the world. Their generous funding has helped lower the cost of the meeting, allowing even more students and scientists to participate. Please join us in thanking our sponsors: GOLD SPONSORS: SILVER SPONSOR: AGENDA Sheraton West Des Moines Sunday, August 12, 2012 Sponsored by DuPont Pioneer 3:00pm - Registration 6:30pm Atrium Set up Posters Polk and Dallas Rooms 6:15pm Welcome Ballrooms Randy Shoemaker, USDA-ARS and Iowa State University, Ames, Iowa 6:30pm DuPont Pioneer Plenary Address Carroll Vance, USDA-ARS and University of Minnesota, St. Paul, Minnesota From George Washington to the Genome: Leveraging Genetics and Molecular Biology to Improve Soybean 7:30pm Refreshments served (Heavy hors d’oeuvres) Atrium Posters open for viewing Polk and Dallas Rooms 8:30pm Dinner – On your own (see restaurant guide in abstract book) 9:00pm Informal Gathering Salon B/C (2nd Floor) Entertainment by the band SEVEN Monday, August 13, 2012 Morning sessions sponsored by Monsanto All sessions take place in the Ballroom unless otherwise noted. 7:00am - Registration Open 10:00am Atrium 7:00am Continental Breakfast Atrium 8:15am Monsanto Plenary Address Jeff J.
