Parasitic weeds threaten California tomato farmers

UC Davis researchers, led by Professor Brad Hanson, combat Orobanche ramosa, a parasitic weed threatening California's $1.5 billion tomato industry. Funded by the California Tomato Research Institute, the multidisciplinary effort focuses on detection, management, and long-term solutions.

Melotto Lab seeks mighty lettuce

Maeli Melotto and her team at the UC Davis Department of Plant Sciences are looking for strains of lettuce that are genetically stronger at resisting bacteria that can make people sick. Their work has led to the identification of a gene that could play a role in the plant’s susceptibility to E. coli, a bacterium that causes potentially lethal intestinal illness.

Taylor Lab looking for genetic secrets to fresher lettuce

Gail Taylor and her team at the UC Davis Department of Plant Sciences are looking for the genetic keys to making America’s favorite leafy green stay fresher, longer, in the fridge.

Taylor and members of the Taylor Lab have found regions on the lettuce genome related to the tiny details of how lettuce leaves are built – structure that can make a leaf more or less hospitable to bacteria. They’ve also found genetic regions related to the plant’s ability to resist bacteria from getting in at all.

Lima bean research awarded $3.3 million from SCRI

Succotash lovers, rejoice: UC Davis researchers will lead a national effort to enlarge the resources for breeding tender, buttery lima beans. The project includes looking at key traits that people and growers want, finding where on the lima bean genome those traits are located, breeding and field trials to grow plants with the most desirable qualities, and creating a public database that other breeders can use to create new and better varieties.

Drought and herbicides: Rice Field Day showcases research

New varieties of rice that offer more effective weed control with less herbicide were showcased by UC Davis Department of Plant Sciences researchers at the recent Rice Field Day north of Yuba City in California's Central Valley. Amid the West’s ongoing drought, green rice with heads full of grain stood tall and lush in some test plots, while dry, brown stubble poked up in others. Department researchers discussed the impact of letting ricelands go fallow, including potential for pest control and ways to conserve soil moisture.
