To manage johnsongrass, a noxious weed that crowds out cotton and sickens horses, farmers have tried herbicides, burning and hand-pulling. Now, researchers at University of California, Davis, have developed a more high-tech weapon against the invasive weed: artificial intelligence and machine learning.

Sustainable orchards, regional pest control and organic agriculture education will advance with three grants awarded to faculty in the UC Davis Department of Plant Sciences. The $5 million in funding for the projects comes through the United States Department of Agriculture.

Blake Meyers, a principal investigator at the Donald Danforth Plant Science Center and a professor of plant sciences from the University of Missouri - Columbia, has been named the new director and Novozymes Chair in Genomics at the UC Davis Genome Center. Meyers, who studies plant RNA biology, bioinformatics and functional genomics, will step into the role on March 1, 2024.

Red, ripe cherries hide in small clusters amid long leaves in the UC Davis teaching orchard. They’re sweet, juicy, beautiful. In area grocery stores, such delights cost up to $8 a pound, but these would have gone to the birds. They must be harvested by hand, and at the price of labor, they’re too expensive to pick, said orchard manager Victor Serratos of the Department of Plant Sciences.

Craft bakers love adding a little triticale to breads for its subtle blend of nutty and earthy flavors and its moist, slightly chewy texture. Farmers love the grain mainly for forage: It produces bigger yields with less water and fertilizer compared to wheat. Now, Joshua Hegarty and colleagues across the country will work on combining those qualities to create new varieties of triticale that are good for bread-baking at commercial scale.

Taylor Swift: A cultural icon, controversial TicketMaster name, and now a remote phenotype (plant trait) monitoring machine. 

Plant Sciences Assistant Professor Troy Magney is a Swiftie to his core. After listening to Swift’s album Folklore on repeat while he was coding and building the instrument in his lab, naming his machine after her was a natural progression. 

Maeli Melotto, a professor in the UC Davis Department of Plant Sciences specializing in plant immunity, has been recognized as a fellow of the American Association for the Advancement of Science, the world’s largest general scientific society and publisher of the Science family of journals.

Researchers at the University of California, Davis, have found a way to reduce the amount of nitrogen fertilizers needed to grow cereal crops. The discovery could save farmers in the United States billions of dollars annually in fertilizer costs while also benefiting the environment.

The research comes out of the lab of Eduardo Blumwald, a distinguished professor of plant sciences, who has found a new pathway for cereals to capture the nitrogen they need to grow.

Perhaps trees aren’t the only green solution when it comes to cooling urban spaces and reducing energy costs. Honeysuckle, Virginia creeper, pink trumpet and other vines could be a fast-growing substitute in climate-smart cities of the future.

Researchers from UC Davis are leading a nearly $880,000 federal grant to study how vines may provide cooling and shade in Western states in less time than it takes a tree to grow tall.

Smoke billows over the forest like a slow-moving fog. Dried oak leaves singe, crackle and curl into ash. Neighbors, scientists and agency staffers rake the embers, directing the flames with calm, careful control. Ted Odell’s grandson runs along his namesake trail, Henry’s Hill, to adjust a hose. 

This is Odell’s property in Placer County, where five of his 11 acres are being burned by prescribed fire with assistance from Placer County Resource Conservation District, UC Davis researchers and others.
