Plant Biology

The College of Biological Sciences is pleased to announce the recipients of the 2025-26 CBS Faculty Research and Teaching Awards. These annual honors recognize faculty members whose contributions exemplify the college's commitment to advancing discovery and providing outstanding educational experiences for students.

As wildflowers go, the mountain jewelflower is demure, clever and quietly unbreakable. It has spread across many of California’s iconic landscapes, from Sonoma wine country to the oak-dotted foothills, even over the Sierra Crest, where snow covers the ground during winter.

The genomics of peppermint are not as fresh as their flavor but scientists from the University of California, Davis, have found a way to breathe new genetic variation into the species.

Salicylic acid, the active molecule in aspirin and some acne medications, is a hormone in plants that is essential for immunity, but it’s a double-edged sword: too much can cause autoimmunity and stunt growth. In a new study published April 20 in Nature Communications, University of California, Davis, researchers discovered that plants use a surprising multi-layered system to regulate salicylic acid levels and keep their immune system in check.

Can the bend of a banana give us insight into cancer? What does the shape of a rice grain have to do with infertility? The proteins that give plants their shape and structure are also involved in human disease. A team led by researchers at the University of California, Davis, has mapped out the structure of a key player, augmin, in exhaustive detail.

Gene editing has enormous potential to help feed the world’s growing population, but it’s currently difficult, time-consuming, and only works in some plant species. A big part of the problem is CRISPR/Cas9’s size: it’s too large to be delivered into plant cells.

Venkatesan Sundaresan, a Distinguished Professor of plant biology and plant sciences at the University of California, Davis, has been awarded a Gates Foundation grant to develop self-cloning crops for Indian farmers.

Two researchers at the University of California, Davis have been awarded a VinFuture Prize in recognition of their work developing self-cloning crops, a breakthrough for sustainable agriculture. 

Sebastian Smith is making less of a career pivot than a total revamp. At age 48, he is getting his B.S., with the goal of earning  a doctorate and becoming a scientific researcher. Just three years ago, he was retiring after a 20-year career in the Air Force. 

Mutations drive evolution, but they can also be risky. New research led by plant biologists at the University of California, Davis, published Nov. 10 in Proceedings of the National Academy of Sciences, reveals how plants control mutation rates in different stem cells to balance adaptability with safety and stability. The findings have implications for breeding some of the world’s most important fruit and vegetable crops, such as potatoes and bananas.
