Welcome

to the

2014 APS-CPS Joint Meeting

Presidents' Welcome “By gathering the diverse domestic and international members of our society, we are able to exchange the latest scientific information, share knowledge on current hot topics being debated publicly, and contribute directly to the grand challenges facing agriculture and society today. Beyond the exciting workshops, sessions and poster presentations, take time to visit the informative booths of our exhibitors and supporters. Sincere thanks to the APS Annual Meeting Board, headquarters staff and members of APS and CPS for planning a comprehensive, balanced and entertaining program for all to enjoy.”

George Abawi, APS President

“The last joint meeting of our two societies was in Quebec City in 2006, so this is a rare opportunity to share our work and be inspired by others from around the world. To fulfill our meeting theme, ‘Plant Health Connections,’ we need to focus on the equation: plant health + soil health + environmental health = community health. This can only be achieved by a vibrant and financially viable agricultural industry. The comprehensive content at this year’s joint meeting will help us address all these concerns to make a real difference.”

Janice Elmhirst, CPS President

Program Chair Welcome “This week, we bring together the greatest minds in plant pathology in the ‘City by Nature,’ Minneapolis. My advice to you is connect. Delve into the future of our science by exploring new topics addressed in posters, technical and plenary sessions. Use the meeting app to stay organized and engaged in the content. Take advantage of the many organized networking opportunities and social gatherings.

I’ve attended APS annual meetings for more than 30 years and I still look forward to meeting friends and colleagues who connect me to my community of science.”

Rick Bennett, APS Program Chair and President-Elect

Safety Tips

Procedures in Case of a Fire

Do not travel alone—stay in groups and travel in well-lit areas.

Remove name badges when outside the hotel or Convention Center unless you are participating in a meeting event.

• Do not give your room number out to anyone you do not know and avoid giving out your room number in conversations where strangers may hear you talking.

• Bolt your hotel room door and only open it when you know who is on the other side. (Note: Hotel personnel wear uniforms and have identification badges. If in doubt, call hotel security to verify an employee’s identity.)

• Do not leave your door ajar if you are going down the hall for ice. Someone may enter when you are not looking.

• Know where the stairs are located in case of a fire (do not use elevators). Also count the number of doors to the nearest exit in case you cannot see in a smoke-filled hallway.

• Valuables, airline tickets, and money should be kept in a hotel safety deposit box or in a room safe, if available.

• Try to leave the hotel as quickly as possible. If you cannot, stay in your room and call the operator or security to let them know you are in your room.

• Put your hand on the room door to see if it is hot before opening it. If it is, do not open it quickly. Open it just a crack to see what is on the other side and be prepared to slam it shut quickly if necessary.

• If you leave the room, take your room key with you! Shut your room door to keep smoke out. You may have to return if the exit is blocked. Remember the way back to your room as you go to the exit in case you need to return.

• If necessary, drop to your knees to avoid smoke. Tie a wet towel around your nose and mouth to act as a smoke filter. Fold it into a triangle and put the corner in your mouth.

• Do not take the elevator when you smell smoke or if you know that there is a fire in the building.

Highlights

Monday, August 11, 10:30 a.m. – 12:00 p.m.; Room 211 CD, Convention Center Biotechnology for improved management of plant diseases has the potential to reduce dependency of commercial and noncommercial growers on pesticides and to enhance food security for an increasing global population. APS has long opposed regulating food, feed, and fiber products based solely on the particular technology that was used to create the varieties/cultivars. However, regulation of newly emerging approaches to crop modification, such as RNAi technology to silence expression of plant, pathogen, or insect genes, is now being discussed. Please join the APS Public Policy Board (PPB) and add to the scientific discussion during this RNAi use for biotechnology hot topic session. An open forum of experts on RNAi will kick off the discussions. A quick highlight on the latest activities for the Phytobiomes Initiative will also be discussed.

Alan Bjerga

Alan Bjerga - Author, Endless Appetites: How the Commodities Casino Creates Hunger and Unrest; Food and Agriculture Policy Reporter, Bloomberg News

With more numerous and diverse media than ever before, engaging with journalists is no longer a choice–it’s a necessity.

But how can a scientist inform the public through the media without risking accuracy or integrity? Alan Bjerga, agriculture reporter for Bloomberg News, discusses ways scientists can better inform the public while helping journalists perform their own function of giving audiences the information they want and need. The presentation will be followed with what promises to be a lively question-and-answer session!

Alan Bjerga is the author of the book Endless Appetites: How the Commodities Casino Creates Hunger and Unrest. He covers agricultural policy for Bloomberg News and is a past president of the National Press Club and the North American Agricultural Journalists. In 2012, he joined the faculty of Georgetown University as an adjunct instructor. He is also a frequent contributor to Bloomberg Television and Bloomberg Businessweek magazine and has discussed food and farming on National Public Radio, the BBC and PBS Newshour, among other outlets. He has been recognized for his work on hunger and agriculture by the Society of American Business Editors and Writers, the New York Press Club, the Kansas Press Association, the North American Agricultural Journalists, and the Overseas Press Club. Bjerga grew up on a farm near the town of Motley, Minnesota. The graduate of Concordia College (Moorhead, Minnesota.) and the University of Minnesota began his career with the St. Paul Pioneer Press (Minnesota) and also reported for the Sioux Falls (South Dakota) Argus Leader and The Wichita Eagle (Kansas). He has competed for the title of “DC’s Funniest Journalist and moonlighted as a game-show contestant, appearing on both “Jeopardy!” and “Who Wants To Be a Millionaire?”

Jennifer Ann Thomson presents – Genetically Modified Crops for Africa: Healthy Plants and Healthy Bodies (Thomson’s talk is provided through the Glenn Anderson Lectureship on World Food Security Award*) Jennifer Ann Thomson

Jennifer Ann Thomson has a Ph.D. in microbiology from Rhodes University in South Africa. She was a post-doctoral fellow at Harvard Medical School. Thomson is now a Professor of Microbiology in the Department of Molecular and Cell Biology at University of Cape Town (UCT) in South Africa and her main current research interests are in the development of maize (corn) resistant to the African endemic maize streak virus (MSV) and tolerant to drought.

Field trials of MSV resistant and drought tolerant maize lines are under way and these will be the first analyses and trials of a transgenic plant developed in Africa, for an African problem, using African plant genes. She is a Fellow of the Royal Society of South Africa and of UCT. Honors received include the L’Oreal/UNESCO prize for Women in Science and an honorary doctorate from the Sorbonne in Paris. Thomson is a regular writer and speaker internationally on the subject of genetically modified organisms, especially crops and foods derived from them. She addressed the World Economic Forum in Davos, and the United Nations as the guest of Secretary General Kofi Annan. Thomson’s two books, ‘Genes for Africa’ and ‘Seeds for the Future’ are geared towards the interested layperson. * Glenn Anderson Lectureship on World Food Security Award was established to commemorate the contributions of an outstanding, internationally recognized plant scientist toward the security of world food supply. The award sponsors lectures either at joint meetings of CPS and APS, at the International Congress of Plant Pathology, or other special events as agreed to by both the CPS and APS, as circumstances permit.

Final Night Celebration— Camp Wanna Mingle

LEADERSHIP OPPORTUNITY Build Better Relationships – Leverage Conflict as Opportunity Highlights

Program

Saturday, August 9; Marquette Ballroom IX, Hilton 8:30 a.m.–5:30 p.m.

Organizers: Janna Beckerman, Purdue University, West Lafayette, IN, U.S.A., and Bill Schneider, USDA ARS, Fort Detrick, MD, U.S.A. Sponsoring Committee: APS Leadership Institute Committee Sponsored in-part by: Monsanto Science is a social occupation. Leaders at all levels need to build positive relationships and manage conflict in productive ways. The inability to do these things can stall or derail a career. Unfortunately, these “soft” skills do not come naturally to all people and are often overlooked in academic coursework. This session will focus on • effective workplace behaviors and building relationships • developing skills to positively resolve conflict in the workplace

Top 7 Reasons to Visit the APS PRESS Bookstore

The session will be facilitated by Sherry Harsch-Porter, Ph.D., president of The Porter Bay Group, Inc. Harsch-Porter also teaches at Washington University and is a contributing author to The Handbook of Knowledge-Based Coaching: From Theory to Practice and author of Education as Possibility: Coaching for Persistence.
