The Citrus Research Board and UC create a $1 million endowment for citrus research
The Citrus Research Board and UC Agriculture and Natural Resources have established a $1 million endowment to fund the Presidential Researcher for Sustainable Citrus Clonal Protection at the UC Lindcove Research and Extension Center. The endowed researcher will provide a UC Cooperative Extension scientist a dedicated source of funds to support scholarly activities focused on the long-term sustainability of the citrus industry.
“I wish to thank the Citrus Research Board for establishing the Presidential Researcher for Sustainable Citrus Clonal Protection at LREC endowment,” said UC ANR vice president Glenda Humiston. “This gift, coupled with the $500,000 match from the UC Office of the President, will help to ensure the long-term success of exemplary research focused on the California citrus industry.”
UC President Janet Napolitano provided half the funds for the endowed researcher; the CRB donated the other half.
“We are gratified that President Napolitano has selected the CRB for this prestigious match program,” said CRB Chairman Dan Dreyer. “It will be invaluable in helping us to pursue critical research that will yield beneficial findings to support the sustainability of the California citrus industry.”
The new endowment supports the UC Citrus Clonal Protection Program, which distributes pathogen-tested, true-to-type citrus budwood to nurseries, farmers and the public to propagate citrus trees for commercial and personal use. The CCPP maintains blocks of trees that serve as the primary source of budwood for all important fruit and rootstock varieties for California's citrus industry and researchers.
The CCPP is a cooperative program between UC ANR, CRB, the California Citrus Nursery Board and the California Department of Food and Agriculture. CCPP director Georgios Vidalakis, UC Cooperative Extension specialist in plant pathology at UC Riverside, shared his appreciation for the efforts that led to the creation of the new endowed researcher position.
“My thanks to the citrus growers for their decades-long support, especially the members of the CCPP committee of the CRB for their vision, and UC's Greg Gibbs for coordinating all of the efforts,” he said. Vidalakis also praised Lindcove director Elizabeth Grafton-Cardwell “for making the case to our growers about the importance of this endowment and for making plans to house the UC ANR endowment at the LREC.”
A selection committee will award the endowment to a distinguished UC ANR academic. An annual payout will be used to provide salary, graduate student and/or program support. The researcher will be named for a five-year term. At the end of that period, the appointment will be reviewed and either renewed or taken back to a selection committee to choose another UC ANR academic.
“I would like to thank the CRB for this generous gift and their continued support of our research for CCPP at the LREC,” said Greg Gibbs,UC ANR director of major gifts.
The CRB administers the California Citrus Research Program, the grower-funded and grower-directed program established in 1968 under the California Marketing Act, as the mechanism enabling the state's citrus producers to sponsor and support needed research. More information about the Citrus Research Board may be found at www.citrusresearch.org.
The Presidential Researcher for Sustainable Citrus Clonal Protection is the fifth $1 million UC ANR endowment to support California agriculture. The other endowments are:
- UC Cooperative Extension Presidential Chair for Tree Nut Genetics, formed with the California Pistachio Research Board in October 2015
- UC Cooperative Extension Presidential Chair for Tree Nut Soil Science and Plant Water Relations, formed with the California Pistachio Research Board in October 2015
- UC Cooperative Extension Presidential Chair for California Grown Rice, formed with the California Rice Research Board in September 2016
- UC Cooperative Extension Presidential Chair for Agricultural Education in Orange County, formed with the Orange County Farm Bureau in October 2017

Larson, Barry win gold for outstanding educational material
Sheila Barry, UCCE livestock and natural resources advisor in the Bay Area, and Stephanie Larson, UCCE livestock and range management advisor in Sonoma County, won the Gold Award for Outstanding Educational Material in the Promotional Materials category from the Association of Natural Resource Extension Professionals.
Decisionmakers and the public have little knowledge of animal agriculture production or the ecosystems services provided by livestock grazing on western open space lands, according to Larson and Barry. To address the issue, they created an information campaign promoting the value of cattle grazing and ecosystem services on open space through curriculum and interpretive trail signage.
The advisors collaborated with the California Rangelands Conservation Coalition and three park districts (East Bay Regional Park Districts, Mid-Peninsula Regional Open Space District, and Sonoma County Regional Parks) to produce signage, factsheets and videos describing ecosystem services and how they relate to California rangelands. The print materials are linked at http://ucanr.edu/sites/BayAreaRangeland.
The three videos are posted on UC ANR's YouTube channel:
- Sharing open spaces with livestock https://youtu.be/Qd8LEGLDhaM
- Sharing open spaces with livestock when you have a dog https://youtu.be/zzdGnfFwmcA
- A year in the life of a cow https://youtu.be/znJbWknVXVg
Susie Kocher, UCCE forestry and natural resources advisor in the Central Sierra area, will accept the award on behalf of Larson and Barry during the awards ceremony May 2 at the ANREP conference in Biloxi, Miss.
APS honors Judelson, Subbarao and Vidalakis
Howard Judelson, professor in the Department of Plant Pathology at UC Riverside, will be named an APS fellow.
“Over his professional life of more than three decades, Judelson has made significant fundamental contributions to studies of oomycete plant pathogens, and has advanced the discipline and mission of APS,” according to the APS website.
“Judelson is recognized for his contributions towards understanding the basic biology and evolution of oomycete plant pathogens. He established the first techniques for manipulating genes in P. infestans and relatives, created genome resources, and studied cellular pathways involved in pathogenesis. Overall, Judelson made significant contribution and achievements in original research, teaching, and professional and public service.”
“Vidalakis has made outstanding contributions to regulatory plant pathology and crop security by playing a leading role in the development and implementation of regional, state, national, and international citrus regulatory protocols in collaboration with industry, scientists, research institutions and regulatory agencies. He has played a key role in the transitioning of the Central California Tristeza Eradication Agency towards the more comprehensive Citrus Pest Detection Program with emphasis on huanglongbing (HLB) diagnostics. The rapid detection and eradication of HLB infected trees in major citrus producing areas of California, such as the San Joaquin Valley, is recognized as one of the most important elements in the battle against the deadly HLB.
“Vidalakis serves on multiple statewide citrus regulatory committees and provides expertise at the highest levels of the California Department of Food and Agriculture (CDFA). One of his major regulatory contributions to California's citrus was his leading role in the development and implementation of the mandatory (SB 140) Citrus Nursery Stock Pest Cleanliness Program that protected the citrus nurseries in advance of the spread of Asian citrus psyllid (ACP) and the discovery of HLB-diseased trees in California.”
“Subbarao's seminal research contributions focus on soilborne fungal diseases affecting lettuce and other cool-season vegetable crops. His recent research has provided crucial novel insights into the biology and management of Verticillium and Sclerotinia pathogens. His work presented convincing evidence that V. dahliae strains pathogenic to lettuce were introduced into the production system via infested spinach seeds.
“Subbarao led the development of the online platform, VertShield, built to share data and diagnostic tools so that others around the world can reliably identify Verticillium pathogens and monitor their movement. Subbarao was also a co-leader in sequencing the first Verticillium genomes, which facilitated subsequent studies on genome evolution and pathogenicity mechanisms.”

ANR reaches out to donors on #GivingTuesday
Last year, the 4-H Youth Development Program and UC Master Gardener Program successfully participated in #GivingTuesday campaigns.
“Our goal for 4-H was to raise $10,000 and we exceeded our goal with donations totaling over $13,000,” said Andrea Ambrose, acting director of Development Services. 4-H programs in 17 counties participated. In Placer County, the robotics team got their friends and family involved to promote #4HGivingConfidence on social media, leading Placer County to collect the largest amount for the 4-H Youth Development Program.
Although not as widely recognized as the shopping events Black Friday and Cyber Monday, #GivingTuesday appeals to people swept up in the spirit of giving at the end of the year.
“#GivingTuesday is a wonderful opportunity for all ANR programs to augment their funding with private donations,” said Ambrose.
A website is being created with links to all of ANR's programs, Research and Extension Centers and extension offices. Donors will be invited to designate the program or location to which they wish to donate. The URL for the #GivingTuesday website will be announced in ANR Update soon.
ANR will provide a toolkit for county offices and programs to participate. It will include:
- A customizable letter to send to stakeholders
- Templates for “unselfies.” Donors may take photos of themselves holding an unselfie sign and share on social media how they are giving.
- Sample tweets and social media posts
- Sample thank you note
UC Research to Policy Conference puts science into action
“We focused on fostering a good dialogue and facilitating co-learning among attendees,” said event co-chair Leslie Roche, assistant UC Cooperative Extension specialist in rangeland management. “We hosted university faculty, statewide CE specialists and academics, and county-based CE advisors—as well as local policymakers and leaders from non-governmental organizations and statewide programs.”
UC researchers who have successfully engaged in the public policy arena provided numerous models of linking research and policy. There were five key take-aways for scientists:
- Honest broker role – Present policymakers with various policy options, based on sound research. Have a clear understanding of the science behind your messaging. Use qualitative data to tell the story of the hard quantitative data.
- Active engagement – Be part of informational and oversight hearings. Empower communities to take action and foster community engagement.
- Build coalitions – Collaboration is imperative. Develop unexpected allies and foster long-term relationships, realizing it may take some time to bear fruit.
- Disseminate information – Share your data in user-friendly formats. Target local community, Legislature and state agencies to inform policies. Get your science into trainings and continuing education programs. Leverage your coalition to expand the circulation of your research results.
- Target messages – Develop a strong, concise message to deliver your research. Use an emotional connection – “Old-growth oak woodlands” versus “oak woodland.”
Throughout the conference, speakers highlighted the multiple levels of engagement for researchers in the policy arena, with different roles matching different needs – some take a center stage, while others play imperative behind-the-scenes roles.
Keynote speaker Jason Delborne, associate professor of science, policy and society at North Carolina State University, encouraged engaging the public. “Science is a social process,” he said, noting that community and public engagement is often key to successfully applying research to policy. Delborne also touched on the tension between expertise and democracy, commenting that we can't always resolve it and often we have to learn to live with this tension.
A diverse set of researchers shared their perspectives from experiences in engaging in policy. The panel included Thomas Harter, Robert M. Hagan Endowed Chair in Water Management and Policy and UCCE specialist in the Department of Land, Air, and Water Resources at UC Davis; Lorrene Ritchie, director of the UC ANR Nutrition Policy Institute; Mindy Romero, founder and director of California Civic Engagement Project at UC Davis Center for Regional Change; and Yana Valachovic, UCCE forest advisor and county director in Humboldt and Del Norte counties. They discussed the importance of building strong science-based programs, actively engaging local communities and building coalitions of support.
Guests from both government and non-government organizations who use research to shape policy shared their perspectives on translating science to decision-making.
“Science is the foundation for developing programs,” said Amrith Gunasekara, science advisor for the California Department of Food and Agriculture.
Tina Cannon Leahy, attorney with the State Water Resources Control Board, noted that policymakers and decision-makers are often looking for a clear, “black-and-white” answer, while for scientists, there is “no answer,” but rather information.
Anne Megaro, consultant to the California Senate Committee on Agriculture, and Rebecca Newhouse, consultant to the California Senate Environmental Quality Committee, both emphasized the importance of making sure science is accessible and digestible.
Juliet Sims of the Prevention Institute explained how her organization uses both published scholarly literature and community stories to effectively inform its advocacy platform.
Keynote speaker Rachel Morello-Frosch, associate professor in the Department of Environmental Science, Policy and Management at UC Berkeley, introduced the concept of moving from “translational research” to “transformational research,” a shift that requires deep community engagement in meaningful ways to effect policy change.
In the afternoon, four breakout sessions were offered: “Policy structures and opportunities for engagement” with Robert Waste, “Relational approaches to science communication and engagement” with Faith Kearns, “Putting it into practice–UC ANR case studies” with Dave Campbell, Clare Gupta and Lucas Frerichs, and “Navigating policy engagement: Education vs advocacy,” with Adrian Lopez and Kit Batten. These training modules helped participants build technical skills and analytical frameworks for successful policy engagement.
The Research to Policy Conference was a forum to exchange ideas and share perspectives, continuing to bridge the gap between science and policy communities. It challenged attendees to be open to new ways of thinking, shared innovative outreach methods and showcased how research can have an impact in the policy arena.
“The event brought cross-fertilization and co-learning between disciplines – nutrition, forest management, water quality – and there were common themes that resonated for all participants,” said event co-chair Gupta, assistant UCCE specialist in public policy and translational research.
VP Glenda Humiston wrapped up the policy conference by saying, "Good science is vital for good policy. It's great to see UC folks enhancing these skills to bring science together with policy."

Pourreza wins international prize for HLB detection
Newly appointed UC Cooperative Extension agricultural engineering advisor Alireza Pourreza has been awarded the 2016 Giuseppe Pellizzi Prize by the Club of Bologna, an honor presented every other year to the best doctoral dissertations focused on agricultural machinery and mechanization. The Club of Bologna is a world taskforce on strategies for the development of agricultural mechanization.
Pourreza, who earned his Ph.D. at the University of Florida in 2014, worked on early detection of Huanglongbing disease of citrus. Huanglongbing, an incurable disease that is spread by Asian citrus psyllid, has seriously impacted citrus production in Florida. The disease has been found in commercial and residential sites in all counties with commercial citrus.
Early detection allows growers to remove infected trees before the disease can spread to healthy trees. Currently HLB infection is confirmed when leaves with yellowing blotches are submitted for PCR testing, which is expensive and time-consuming. However, the yellowing can be also symptomatic of other conditions, such as nutrient deficiency.
"We discovered we could see the symptoms of Huanglongbing using a camera, a set of cross-polarizers and narrowband lighting before it is visible to the human eye," said Pourreza, who is based at the UC Kearney Agricultural Research and Extension Center in Parlier.
He said the yellow blotches on HLB-infected leaves are caused by starch accumulation.
"If we could detect abnormal levels of starch in the leaf, we could tell it is affected with HLB," Pourreza said. "Starch showed the ability to rotate the polarization plane of light. We used this optical characteristic to develop the sensing methodology."
Pourreza said the team has patented the technique and is working on developing a commercial product. He is seeking funding to continue the research in California, where, to date, HLB has only been detected in isolated Los Angeles neighborhoods. Asian citrus psyllid is found in important California commercial citrus production regions from the Mexican border to as far north as Placer County.
4-H Youth Development team wins national diversity award
4-H Youth Development advisors Dorina Espinoza, Russell Hill, Fe Moncloa and Keith Nathaniel and 4-H associate director Shannon Horrillo have won the National Extension Diversity Award for systematically enhancing the intercultural competency of 4-H personnel and others in California.
The award, given by USDA National Institute of Food and Agriculture (NIFA), Cooperative Extension System and the Association of Public and Land-grant Universities (APLU), honors the team for creating and using Intercultural Development Inventory© to shift organizational culture. This shift includes mutual respect, acceptance, teamwork and productivity among diverse people.
To meet the needs of a culturally and ethnically diverse youth population in California, they created a professional-development intervention for 4-H academics and staff. The Intercultural Development Inventory© is a cross-culturally generalizable, valid and reliable assessment of intercultural competence. Calling themselves the Intercultural Development Inventory Qualified Administrators, they applied the strategy over three years, providing 176 hours of intercultural communication feedback sessions, learning communities and regional conferences to enhance the intercultural competence of 65 4-H personnel.
Evaluations demonstrated that after the intervention UC 4-H Youth Development Program personnel had acquired skills and characteristics to become more culturally competent. The program has moved from focusing on similarities across diverse people that can mask deeper recognition of cultural differences to recognizing the complexity of dimensions of diversity.
The action plan and resulting positive change provides the potential to improve hiring and professional development nationwide by replication in other states. A summary of California's IDI professional development activities can be found in the National 4-H Latino Youth Outreach: Best Practices Toolkit, Professional Development.
The National Extension Diversity Award will be presented on Nov. 13 at the 129th APLU Annual Meeting in Austin, Texas.
