The annual CBS Dean’s Summer Undergraduate Research Program (SURP) supports students who wish to stay on campus—and in the lab—over the summer terms.

Normally, undergraduates leave campus for the summer if they are not enrolled in classes. They often do this to work and save funds for the start of the next academic year. SURP consists of several different donor-funded undergraduate research awards and allows students to continue their research projects over the summer.

A new study from UC Davis researchers shows that when oak trees die, it triggers major changes to the community of soil microbes living beneath them. These changes have implications for soil health that could ripple out to impact entire ecosystems, especially given the recent rise in tree deaths due to droughts and wildfires.

Plant biology is the study of how plants grow, function and respond to their environments. Plant biologists address challenges like food security, climate change and sustainable agriculture. It’s no exaggeration to say that all life relies on plants. 

“Plants feed the world,” says Danielle Levi, my labmate in the Zerbe Lab and a third-year plant biology major. “Climate change is threatening global food security, and we need to find more sustainable ways to feed our growing population while minimizing environmental impacts.” 

Three College of Biological Sciences research core facilities are among 20 across UC Davis selected to receive funding through the university's new Research Cores Central Investment (RCCI) Program. The one-time awards will help sustain essential shared research infrastructure, supporting advanced imaging, plant growth facilities, and other specialized resources that enable discoveries across the biological sciences.

Xiaosa Xu, assistant professor of plant biology in the College of Biological Sciences, has received a UC Office of the President Early Career Faculty Research Excellence Award. The award includes $50,000 to support his research on the evolution of maize.

Philipp Zerbe, a professor of plant biology whose research explores how plants use chemistry to communicate with and adapt to their environment, has been named associate dean for research and graduate studies for the College of Biological Sciences. He will begin serving in the role on September 1.

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.
