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.
Plants produce thousands of chemical compounds that help them attract friends and deter foes. Many of these compounds, or “metabolites,” have been harnessed by humans in fragrances, medicines, and biofuels.
Houseplant aficionados, start your engines! More than 60 species of tropical plants—including some rare species, carnivorous plants, succulents, and more—will be on offer on Saturday, April 19 from 10:00am until 2:00pm at bargain prices, as the UC Davis Botanical Conservatory resumes its highly popular plant sales.
A battle around the world is raging between plants and the changing environment, and UC Davis researchers are on the front lines.
For example, the microbes are constantly creating new types of illnesses, while the plants — sometimes with the help of breeders — are developing new immunities.
It’s something plant geneticist Luca Comai, Ph.D. ’80, a distinguished professor of plant biology, has seen firsthand through his decades of research into plant chromosomes.
Each year, nearly 30 million Americans purchase a real tree for the holidays. Growing the perfect Christmas tree takes about seven years, during which farmers need to keep insects, fungal pathogens and hungry deer at bay. While researchers suspect the distinctive piney smell the trees emit plays a role in deterring these pests, not all trees smell the same, and which chemical blends confer resistance is unclear.
Rice is a staple food crop for more than half the world’s population, but most farmers don’t grow high-yielding varieties because the seeds are too expensive. Researchers from the University of California’s Davis and Berkeley campuses have identified a potential solution: activating two genes in rice egg cells that trigger their development into embryos without the need for fertilization, which would efficiently create high-yielding clonal strains of rice and other crops.
The work of 12 early-career faculty members will get a boost as this year’s class of Hellman Fellows. They will receive grants ranging from $16,000 to $49,000, for a total of $330,000 awarded.
Their work covers a wide range of topics, from the educational experiences of Venezuelan immigrants to a wireless device that monitors for seizures.
The college was pleased to welcome five new faculty members to its ranks during the 2023-24 academic year. Joining the Departments of Plant Biology, Molecular and Cellular Biology, Neurobiology, Physiology and Behavior, and the Center for Neuroscience, each faculty adds breadth and depth to the college’s research and teaching portfolio.
For many plants, more branches means more fruit. But how does a plant branch or not branch? New research from the Department of Plant Biology has shown how plants break down the hormone strigolactone, which suppresses branching, to become more “bushy.” Using a combination of structural biology, biochemistry, and genetic engineering, the team confirmed the specific enzymes responsible for dismantling strigolactone, and their mechanism. Understanding how strigolactone is regulated could have big implications for many crop plants.
It wasn’t until Dustin Lower returned to college after more than a fifteen-year break that he finally found his niche, and a long sought-after green thumb.
Savithramma P. Dinesh-Kumar, Professor and Chair in the Department of Plant Biology, is one of the three professors from the University of California, Davis, have been elected as members of the National Academy of Sciences. They are among 120 new members and 24 international members announced by the academy April 30.
Joel Ledford, an associate professor of teaching in the Department of Plant Biology, has received the 2024 Excellence in Teaching Award from the Associated Students, University of California, Davis (ASUCD). The annual award celebrates teaching faculty for their dedication to students and undergraduate education.
“Getting an award like this from students means a lot to me,” Ledford said. “It’s an inspiring thing, and it makes you want to be a better teacher.”
