Researchers with the French Agricultural Research Centre for International Development (CIRAD) recently visited Brazil to discuss cooperative efforts with Fundecitrus to develop greening-resistant orange trees. The CIRAD researchers were Raphaël Morillon and Bárbara Hufnagel. CIRAD is an agronomic research and international cooperation organization for the sustainable development of tropical and Mediterranean regions. CIRAD maintains a large citrus genomic database on …
By Lauren Diepenbrock and Nicole Quinn In recent years, a new pest has been added to the ever-evolving scope of pest management in Florida citrus: Bulimulus bonariensis snails. These snails, also referred to as ghost snails or peanut snails, were reported to be clogging irrigation jets in Central Florida in 2020 in limited locations. Now, in 2025, they have spread …
Research by the University of Miami’s College of Arts and Sciences aimed at protecting the Florida scrub has spurred a related study of microbes found in the soil of former citrus groves. The citrus research is led by Joshua Fowler, a postdoctoral research associate. The sandy, well-drained soils of the Florida scrub, which support many native plants, also provide ideal …
The 2025 Florida Citrus Growers’ Institute had a different setup compared to previous years. Scientists from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) convened at South Florida State College in Avon Park on April 8 to share research that will help shape the future of the Florida citrus industry. Chris Oswalt, UF/IFAS citrus Extension agent who …
A research team led by Jian Ye from the Institute of Microbiology of the Chinese Academy of Sciences has identified the first mechanism of citrus resistance to HLB. Results of the study were published in Science. Utilizing artificial intelligence (AI), the team has also developed antimicrobial peptides that offer a promising therapeutic approach to combat the disease. This discovery addresses …
Parasitic weeds are ruthless freeloaders, stealing nutrients from crops and devastating harvests. But what if growers could trick these invaders into self-destructing? Scientists at University of California, Riverside (UCR) think they’ve found a way to turn the weeds’ own biology against them. This trick is detailed in the journal Science. At its heart lies a class of hormones called …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center in Immokalee hosted a citrus field day on April 10. The event showcased the research being conducted at the center. One of the tour stops featured individual protective cover (IPC) research led by Fernando Alferez, UF/IFAS associate professor of citrus horticulture. Thanks in …
A pioneering study has uncovered the role of a key gene, PtrPAT1, in boosting cold tolerance in citrus plants by regulating the accumulation of glycine betaine (GB). This breakthrough deepens understanding of how plants cope with cold stress and opens the door to developing cold-resistant citrus varieties. Citrus plants, traditionally cultivated in tropical and subtropical climates, are highly vulnerable to …
Scientists with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and the U.S. Department of Agriculture Agricultural Research Service (USDA/ARS) recently wrote about efforts to identify HLB-affected versus healthy citrus fruit. UF/IFAS scientists are Mark Ritenour, Ketan Shende and Thomas Burks. Michelle Heck is with the USDA/ARS. A slightly edited version of their article follows: Most citrus …
Eating an orange a day may lower a person’s depression risk by 20%, according to a study led by Raaj Mehta, an instructor in medicine at Harvard Medical School. Mehta is also a physician at Massachusetts General Hospital. Mehta said a postdoctoral student he was working with found a 2016 paper pointing to the possibility that citrus lowers the risk …
A tool predicting how to protect European citrus from HLB shows how mathematical modeling can help prepare for future plant disease invasions. Europe is currently unaffected by HLB. However, there are increased concerns of an infestation since psyllids that spread HLB have been found in key citrus-producing countries, including Portugal and Spain. In response to the HLB threat, a new …
Those involved with the University of Georgia (UGA) citrus research plot in Valdosta are often asked what they do with the fruit once it is harvested. All of the citrus is donated to various groups, reports the team of Jake Price, Mary Sutton, Doug Collins, Jacob Kalina, Josh Dawson, Holly Anderson, Michasia Dowdy, Sara Curry, Ben Reeves, Tucker Price and …
Two University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) scientists reported on research into more effective and environmentally friendly degreening methods for fresh citrus. They are Muhammad Shahid and Muhammad Nadeem, assistant professor of horticulture and postdoc scholar, respectively, at the UF/IFAS North Florida Research and Education Center (NFREC). Edited excerpts follow: Some varieties of citrus fruit, even …
Rick Dantzler, Citrus Research and Development Foundation (CRDF) chief operating officer, reported that the foundation’s January board of directors meeting was a productive one that resulted in the approval of several key citrus research projects. “We had a great meeting. The board approved funding to use a strain of Bacillus thuringiensis (Bt) to kill the progeny of psyllids,” Dantzler said. …
The U.S. Department of Agriculture (USDA) announced an investment of more than $70 million in the Plant Protection Act program. This includes funding of 357 projects in fiscal year 2025. The work will strengthen the country’s defenses against plant pests and diseases, safeguard the U.S. nursery system, and enhance pest detection and mitigation efforts. Part of the funding is going …
Recently, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) reported research on the development of a new type of citrus tree that can fight off the HLB-spreading Asian citrus psyllid (ACP). The genetically modified tree has only been tested in the lab and the greenhouse, but the research looks promising. The approach involves inserting a gene into …
A groundbreaking research collaboration led, in part, by Indian River State College Professor Tom D’Elia, has resulted in the successful annotation of the Asian citrus psyllid genome. This marks a significant advancement in the fight against citrus greening disease. The research, published in GigaScience, represents an achievement in both scientific discovery and undergraduate education, featuring 28 Indian River State College …
By Peter Chaires Florida’s citrus industry is well supported by two phenomenal research institutions: University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS). UF/IFAS provides research and Extension support from its main campus in Gainesville, as well as from its research and education centers and county Extension offices across the state. …
Scientists have decoded the intricate metabolic profiles of citrus fruits, shedding light on the phenylpropanoid pathway. The pathway is a critical biosynthetic route for flavonoids and other phytonutrients known for their health benefits. By revealing the genetic mechanisms underlying these compounds, the research offers an approach to enhancing the nutritional value of citrus through innovative breeding and genetic improvement strategies. …
In an advance that could change how millions of patients take their medications, researchers have identified the genetic mechanism behind grapefruit’s notorious interaction with prescription drugs. The discovery opens the door to developing new varieties of grapefruit that won’t interfere with medications, potentially allowing patients to safely enjoy the fruit again. For decades, healthcare providers have advised patients to avoid …
