Discolored leaves. Decaying roots. Dead wood. Mother Nature offers a fascinating and colorful backdrop of clues to track microscopic killers. Much like any medical mystery, experts are called in to diagnose or identify a disease from its symptoms and recommend management strategies to prevent further damage or loss of healthy plants.
Humans and animals depend on plants for their food supply and ultimately for their survival. When diseases threaten crops, a high-quality, affordable food supply is placed at risk. For growers, plant diseases can reduce crop yields. For consumers, reduced crop yields can drive higher food prices. Plant pathology research holds enormous implications for a sustainable food supply.
Florent Trouillas, who was named UC Cooperative Extension specialist in the Department of Plant Pathology at UC Davis and the Kearney Agricultural Research and Extension Center last year, explains the bottom line of most concern to growers.
"Once we identify a disease causal agent, a main question remains from growers. What growers really want to know is how to control the disease and prevent its spread to new healthy plants; they look to the University of California for solutions," Trouillas said.
A crisis in the food production system can impact other areas of society as well. In fact, history is filled with examples of how plant diseases influenced economies, environments and human societies.
Another historical illustration of plant pathology research occurred in the 1920s. The most common trees in the forests of the United States at the turn of the century were the majestic American chestnuts. The trees generated income for humans and the timber industry, served as a food source for people and animals, and provided habitat for wildlife. Then the trees started dying, until by the late 1920s, they had become the first tree in modern times on the brink of extinction. Plant pathologists were particularly adept at identifying plant diseases by this time and diagnosed the Cryphonectria parasitica fungus as the cause of the chestnut blight. By preventing the extinction of the pivotal species, plant pathology had a direct impact on the economy and the environment.
More recent major plant disease outbreaks in the United States involving plant pathology research have included Sudden Oak Death with devastating effects in California and Oregon forests, pitch canker killing California native pine species, and citrus canker in Florida, which has had a huge economic impact on the industry.
Veterinarians treat diseases in animals, physicians in humans. Trouillas describes the role of plant pathologists in similar terms. “We study the pathology of plant systems. Plant pathologists treat plants," he said.
Healthy plants ensure a sustainable food source and habitat for so many other organisms, including the human species.
The award was presented to the Aggie inventors during the finals of the three-day global iGEM (International Genetically Engineered Machines) competition in Boston. The competition, this year featuring 245 teams from Asia, Europe, Latin America and North America, challenges student teams to design and build biological systems or machines and present their inventions in the international competition.
The students had spent several months designing and building the palm-sized biosensor, which they dubbed OliView. The biosensor is equipped to quickly and easily evaluate the chemical profile of oil, providing producers, distributors, retailers and ultimately consumers with an effective, inexpensive way to ensure olive oil quality.
Verifying olive oil quality is a concern for consumers – many of whom are willing to pay higher prices for the health benefits and flavor of true, extra-virgin olive oil. And honest olive oil producers want to prevent other producers from passing off sub-par olive oil as the real deal, while retailers, distributors and producers want a quick, easy way to ensure olive oil quality.
In addition helping detect fraudulent olive oil, the students' new biosensor will also monitor for good oil that may have gone rancid with age.
The team of undergraduate students included Lucas Murray, Brian Tamsut, James Lucas, Sarah Ritz, Aaron Cohen and Simon Staley, with Yeonju Song serving as the “shadow” or alternate team member. You can tune into Aaron Cohen's recent Nov. 6 Science Friday interview during a discussion of synthetic biology.

On July 1, the University of California announced our new Global Food Initiative to address one of the critical issues of our time: How to sustainably and nutritiously feed a world population expected to reach eight billion by 2025.
UC's Division of Agriculture and Natural Resources is already a critical partner with California's farmers and consumers, providing growers and ranchers with scientifically tested production techniques, educating families about nutrition, improving food safety and addressing environmental concerns. With programs in every California county, our research and extension network in California reaches from Tulelake to El Centro and more than 130 countries working to solve agricultural problems at home and abroad.
The initiative will align the university's research, outreach and operations in a sustained effort to develop, demonstrate and export solutions — throughout California, the U.S. and the world — for food security, health and sustainability.
Check below for some key highlights from UC ANR and our 10 campuses. For more information about the initiative, visit: http://www.ucop.edu/initiatives/global-food-initiative.html

But the truth is, dietary advice is nothing new. Some of our rules for eating date back to ancient times as part of religious teachings, and food traditions are central to our understanding of culture. What is new over the last century or so is the application of science to our diets, so that we can know more exactly what nutrition science tells us is best when it comes to filling our plates.
A new book by a UC Davis researcher argues that modern dietary advice is not merely scientific, but also continues to have cultural, ethical and moral messages attached to it.
“Eating Right in America: The Cultural Politics of Food & Health” analyzes how modern dietary reform movements in the United States do not just tell us how to eat right, but how to become a good person and a good citizen. Can eating a certain way make us into different, somehow better people? And who defines what sort of people we should strive to become, though improved eating? Author Charlotte Biltekoff calls for changing the way we think about what it means to “eat right.”
The book analyzes four dietary reform movements over the last century:
- the rise of domestic science and home economics,
- the national nutrition program during World War II,
- the alternative food movement, and
- the anti-obesity movement.
These reform movements cover nutritional advancements such as the science of cooking, the discovery of vitamins, the shift in emphasis from contagious to chronic diseases, and the increasing importance of diet and lifestyle as a part of health. The book examines how dietary ideals have shifted, how social ideals have shifted alongside them — and the relationship between the two. Notions of middle class identity, good citizenship and individual responsibility each have been mixed in with nutritional advice before it is served to the public, according to the author.
Rose Hayden-Smith, leader of UC ANR’s Sustainable Food Systems strategic initiative and a historian of gardening, said she can't wait to read this book.
“This whole idea of both empirical and ethical considerations of food choices really makes sense to me, rooted in the Progressive Era,” she said. “All of these scientific advances don’t matter if people don’t adopt them. So I think it’s really important for scientists to understand the cultural context into which their work is going.”
Beth Mitcham, UC Cooperative Extension specialist in the Department of Plant Sciences at UC Davis, was intrigued by a presentation given by Biltekoff at UC Davis recently.
“This expands my way of thinking about the struggles we have with food choices and the potential for complicating well-intentioned messages,” she said. “We can’t ignore the scientific evidence that food choices have a huge impact on our health, but we must also realize when the things we’re saying are charged with judgments."
In a recent interview on Capital Public Radio, Biltekoff pointed out how analyzing history can shed light on difficult truths.
“History is such a great tool for learning to see things differently,” Biltekoff said. “The history that I tell in the book suggests that we worry so much about what is good to eat because of the social stakes involved in 'eating right.' Because it’s not just about our physical health, but also about our sense of self and about our social standing. There's a lot at stake that we may not be conscious of, but really is part and parcel of the conversation about 'good' food.”/span>
“Food commands attention and brings people together,” says L. Ann Thrupp, executive director of the Berkeley Food Institute, a new interdisciplinary research center comprising five different UC Berkeley schools. “It touches on every aspect of human society.”
It’s bringing academia together, too. Food research centers have been springing up at campuses across the United States as higher education takes on the complex topic from multiple perspectives.
“The academic community is recognizing that when it comes to food, it’s no longer possible to tease out agriculture from environmental, public policy, social justice and public health issues,” Thrupp says.
UC Berkeley’s new initiative is ambitious. In development for nearly two years before its launch this fall, the center has a mission to help achieve transformation in the food and agriculture systems, making them more diverse, healthy, resilient and just — at local, regional, national and international levels.
The Institute will pursue that transformation by supporting and galvanizing collaborative research efforts across its five partner units — Berkeley Law, the Goldman School of Public Policy, the Graduate School of Journalism, the School of Public Health, and the College of Natural Resources (CNR) — and with faculty affiliates throughout the University.
But, as befits Berkeley’s storied history of activism and leadership, the Institute’s vision is larger than publishing in academic journals. Its leaders plan to break down the traditional boundaries between academia and society and connect with boots-on-the-ground stakeholders who can help identify knowledge gaps and use research to bring about real changes in the food system.
“It is not enough to conduct research — the fruits of this research must be delivered broadly to civil society and to policy makers,” says Claire Kremen, a conservation biology professor and one of the Institute’s two faculty co-directors. “That’s why the schools of journalism and of public policy are key collaborators. They have the expertise to communicate our findings to key sectors and actors in society and government.”
Thrupp echoes the point. “Making an impact will require the engagement of multiple sectors, including scientists, farmers, food system workers and policymakers — at all levels,” she says. “The Berkeley Food Institute will help facilitate those crucial connections.”
This fall, two heavy-hitters from far-flung corners of the food world are helping the Institute start making those connections, as its first visiting scholars. Olivier de Schutter, the United Nations’ Special Rapporteur on the Right to Food, fights hunger worldwide and defends food as a “human right.” Saru Jayaraman, head of the UC Berkeley’s Food Labor Center, has fought to improve wages and working conditions for food workers, and to broadly communicate the issues they face.
The next panel, “The Right to Food: Reshaping Policies for Development and Public Health,” scheduled for Oct. 28, is moderated by J-School Dean Edward Wasserman and features De Schutter and public health and ag-econ faculty.
The fall programs culminate with “What’s Next for the Food Movement?” a conversation between author and journalism professor Michael Pollan and, fresh from the Obama administration, former Deputy Secretary of Agriculture Kathleen Merrigan. It’s moderated by journalist Linda Schacht.
The dynamic public events series, what organizers are calling “The Food Exchange,” is just a taste of the conversations, investigations, and collaborations to come, both behind the scenes and in a public forum.
“It’s inspiring that so many researchers, students, stakeholders and community members are interested and involved in the Berkeley Food Institute and our mission,” Thrupp says.
