Crossroads in Science

The American Phytopathologoical Society

Welcome

to the 2015 APS Annual Meeting

On behalf of The American Phytopathological Society, I’m pleased to welcome you to Pasadena for the 2015 Annual Meeting. The theme of this year’s annual meeting, “Crossroads in Science”, reflects the unique position our discipline holds within the broad field of plant sciences. Our meeting will offer the latest advances, innovations, and discoveries as we explore new ways to connect with the worldwide community of scientists. Our Plenary Sessions will offer a dynamic look into the future of our science, and we will have fun examining generational perspectives among our membership. Our scientific program will include special sessions, workshops, technical sessions, and educational opportunities including field trips and workshops. As always, we encourage you to take full advantage of the many social gatherings and networking events to renew old friendships, establish new relationships, and meet the next generation of plant pathologists.

Welcome to the 2015 APS Annual Meeting. We’re glad to see you in Pasadena!

Rick Bennett, APS President

We are coming together this week to share the latest science in the plant pathology community and to explore great work in interconnected disciplines. I am excited about the opportunities to learn, share, and network through posters, technical and special sessions, plenary sessions, and plenty of social events. Students, don’t be shy and join in the mix, introduce yourselves to fellow scientists and educators, join a committee, contribute to Idea Cafés, or join the discussion around a Poster Huddle. The meeting app will help us all stay organized and remember all of our “must do” events. Let’s all have a great meeting in the beautiful “City of Roses!”

U.S. Food Waste Challenge On June 4, 2013, the U.S. Department of Agriculture (USDA), in collaboration with the U.S. Environmental Protection Agency (EPA) launched the U.S. Food Waste Challenge, calling on others across the food chain—including producer groups, processors, manufacturers, retailers, communities, and other government agencies-to join the effort to reduce, recover, and recycle food waste. APS supports this effort by working with the hotels and convention centers to donate food from APS meetings to food shelves in the local area.

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.

A grand selection of items from around the world will again be available at this year’s 11th Annual Silent Auction. Proceeds fund the APS Office of International Program’s Global Experience Program. Support this effort with your bids on Sunday, August 2, 12:00 – 6:00 p.m.

Program Highlights APS Reaches Out with Global Connections through Live Streaming

PLENARY SESSION I

Doug Parker– Ph.D., Director, California Institute for Water Resources, University of California, Agriculture and Natural Resources, Oakland, California, U.S.A. California is now into its fourth year of record-breaking drought.

Water restrictions and a call for mandatory reductions have impacted all users of water in California. These historic conditions have everyone looking for a silver bullet solution to California’s drought.

The fact is that in this large and semi-arid state, water is intimately tied to every aspect of life. To understand California’s water situation, one must recognize a fundamental paradox: Enough will never be enough.

We are a land-rich but water-limited state, and increased supply leads to more demand, which makes answers to California’s water challenges complex, involving a combination of policy, technology, and conservation.

Back for a second year! PhytoView Sessions Protecting Seed Health: More than the Eye Beholds

Sunday, August 2, 1:00 – 2:15 p.m.; Ballroom C, Convention Center

Doug Parker is director of the California Institute for Water Resources where he has held that position since 2011. He is also strategic initiative leader for water quality, quality and security at the University of California, Division of Agriculture and Natural Resources in Oakland.

Prior to becoming director of the California Institute for Water Resources, Parker was the director of the MidAtlantic Water Program at the University of Maryland at College Park and associate professor in Cooperative Extension.

Crossroads in Science

Michael Rogers – Author, Technology Pioneer, and Futurist The 21st century has brought enormous opportunities to the life sciences: big data, cognitive computing, and increasingly inexpensive tools for genomics.

But the challenges have grown also, from the needs and impacts of a still-rising world population to the decrease in public funding for research and development. Add to that a generalized public mistrust of any work that involves “genetic engineering,” and you have a complex environment indeed. What kind of careers lay ahead for young scientists, with the rise of peer-topeer innovations like crowdfunding and open access journals? How do older researchers adapt to disciplines that seem increasingly driven by algorithms? And what is the responsibility of scientists to speak out on global issues that may well threaten life as we know it? Find answers to

PLENARY SESSION II When Generations Connect: Communicating with Four Generations of Employees

Tuesday, August 4, 1:00 – 2:00 p.m.; Civic Auditorium, Convention Center Scott Zimmer – Generation Expert, BridgeWorks (Bridging the Generational Divide), Minneapolis, Minnesota, U.S.A.

APS takes to the streets during this outdoor celebration that goes into the night and under the stars. Enjoy California fusion cuisine, great conversation, and music by the Lucky Devils Band! It’s a great way to wrap up the meeting and make one final connection with your colleagues and friends before heading home. Ticket to the event and a drink ticket are included with full registration. Guests’ tickets are available for purchase at the Registration Desk.

Four distinct generations are working together shoulder to shoulder, each with a unique set of attitudes, values, and work styles. It used to be that older workers were bosses and younger ones took orders. Now, roles are all over the map and rules are being rewritten.

Businesses and institutions are feeling the pain of generations and they struggle to manage productivity and morale while maintaining high standards and morale. This program will give you the tools to convert this form of diversity from an obstacle to an opportunity.

LEADERSHIP INSTITUTE: EI and IP– Core Tools for Science Leaders

Scott Zimmer (Generation Xer) is a writer, market researcher and generational expert with BridgeWorks, a Minneapolis based company that has been dedicated to bridging the generational divide in the workplace and marketplace for more than 16 years. A child of the 80s and 90s, Zimmer has insider knowledge into what makes these generations tick. Sandwiched between the idealistic Boomers and the innovative Millennials, his Xer lens allows him to hone in on the key challenges facing each generation.

Returning to APS! PhytoViews Your opportunity to engage in facilitated conversations as we explore all points of view on these topics of interest!

Protecting Seed Health: More than the Eye Beholds

Sunday, August 2, 1:00 – 2:15 p.m.; Ballroom C, Convention Center Moderator: Lindsey du Toit, Washington State University Panelists: • Gary Munkvold, Iowa State University • Samantha Thomas, Monsanto Vegetable Seeds • TBA, USDA APHIS PPQ Seed Specialist Join us to explore the complexity of seed pathology and seed health testing. Public and private sector seed pathologists will serve on a panel to answer questions and lead a discussion on seed testing methods, robust validation of seed health testing methods, seed certification based on standardized seed assays, testing treated vs. nontreated seeds, differentiating viable vs. nonviable seedborne inoculum, seed lab certification, thresholds for seedborne pathogens, and the impacts of current seed regulations and inspections as well as new initiatives with the seed industry to reduce the risks of seedborne pathogens associated with movement of seed.

The Phytobiomes Initiative: Something for Everyone

Tuesday, August 4, 2:15 – 3:30 p.m.; Ballroom E, Convention Center Moderator: Kellye Eversole, Eversole Associates Panelists: • Melanie Lewis Ivey, Department of Plant Pathology and Crop Physiology, Louisiana State University • Kirk Broders, Department of Biological Sciences, University of New Hampshire • Linda Kinkel, Department of Plant Pathology, University of Minnesota The Phytobiomes Initiative (phytobiomes.org) is a major focus of APS advocacy with government agencies through the Public Policy Board. The initiative promotes funding of research that will lead to an understanding of phytobiomes and how the information gained can be used to improve crop production, quality, and safety. Have you wondered how the Phytobiomes Initiative can help you serve your clientele better with research that directly addresses important plant health issues? Have you wondered if your science is part of the Phytobiomes Initiative? Through interactive exchange with panel members, this PhytoViews session will update participants on opportunities and explore needs for translational research with near-term applications.
