The rhizosphere, defined as the soil environment that surrounds the plant roots, is a rich and diverse habitat for microbes. Some members of the rhizosphere microbiome (or collection of microbes), are good, others bad while many are just there and don’t provide any benefits or harm to the host. One function of the good microbes in the rhizosphere is to …

New research affirms a unique peptide found in an Australian plant can destroy the No. 1 killer of citrus trees worldwide and help prevent infection. Huanglongbing, HLB, or citrus greening has multiple names, but one ultimate result: bitter and worthless citrus fruits. It has wiped out citrus orchards across the globe, causing billions in annual production losses. All commercially important …

New grants totaling $6.3 million will help UC Riverside solve problems facing American avocado orchards, including a lethal fungal disease called Laurel Wilt. Laurel Wilt can destroy an entire avocado orchard in a couple of weeks once symptoms develop. It is already present in Florida. Without effective treatments, it will inevitably spread to California, which is the nation’s leading producer …

Every backyard gardener knows how hard it can be to tell when to water the plants. Multiply that by tens or hundreds of acres and it’s easy to see the challenges growers face keeping their crops healthy while managing water resources wisely. To determine water needs accurately, growers hand-pluck individual leaves from plants, put them in pressure chambers, and apply …

Scientists are closer to gaining the upper hand on a disease that has wiped out citrus orchards across the globe. New models of the bacterium linked to the disease reveal control methods that were previously unavailable. Metabolic models of organisms are like road maps of cities. “They show you all the biological processes, and how they work together,” said UC …

UC Riverside scientists have found the first substance capable of controlling Citrus Greening Disease, which has devastated citrus farms in Florida and also threatens California. The new treatment effectively kills the bacterium causing the disease with a naturally occurring molecule found in wild citrus relatives. This molecule, an antimicrobial peptide, offers numerous advantages over the antibiotics currently used to treat the …

UC Riverside has entered into a $2.25 million partnership with Spain-based Eurosemillas S.A., a global leader in the commercialization of agriculture innovations, to help the university bring to market the most promising and advanced avocado scions and rootstocks in its collection. If successful, these varieties would meet diverse regional growing requirements, exhibit better post-harvest characteristics, increase yields, provide resistance against …

UC Riverside and the California Citrus Research Board would like to invite growers and industry stakeholders to attend the 9thannual UC Riverside Citrus Day for the Industry to be held at UC Riverside Ag Operations (1060 Martin Luther King Blvd., Riverside) on January 29, 2020.  Registration will begin at 7:30 a.m. and will cost $35 (Lunch is included).  The deadline …

If you’re eating fruits, nuts, grains, or vegetables in a few years, you’ll likely owe a debt of gratitude to UC Riverside. The university has created a program to transition today’s undergraduates into professional scientists solving tomorrow’s farming challenges. The program, called Plants-3D, will train students to discover, design, and deploy biology and engineering solutions to the projected problem of …
