Breeding Hybrids With HLB Resistance
UC Riverside scientists are working to breed new fruits that are naturally resistant to huanglongbing (HLB). The hybrid fruits will ideally share the best of their parents’ attributes: the tastiness of citrus and the HLB resistance displayed by some Australian relatives of citrus. HLB, also called citrus greening disease, has been detected in California, where 80 percent of the country’s …

Using Grapefruit to Deliver Medicine
University of Louisville (UofL) researchers have found a less toxic way to deliver medicines by using the natural lipids in plants, particularly grapefruit and ginger. The UofL technologies use exosomes, which are very small fragments of living, edible plant cells, to transport various therapeutic agents, including anti-cancer drugs, DNA/RNA and proteins such as antibodies. These exosomes help ensure the drug …
