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. 

Redwoods are among the most well-studied trees on the planet, and yet their mysteries continue to surprise and delight scientists and nature lovers. 

A team of scientists from University of California, Davis, have identified a new gene variant in wheat that can increase the amount of the grain produced, new research published in the journal PLOS Genetics finds.

Wheat is a staple of food diets worldwide and the gene discovery could allow farmers to grow more food without increasing land use. Increased yield could also lower consumer prices, making the crop more accessible.

What does a “resilient” forest look like in California’s Sierra Nevada? A lot fewer trees than we’re used to, according to a study of frequent-fire forests from the University of California, Davis.

More than a century ago, Sierra Nevada forests faced almost no competition from neighboring trees for resources. The tree densities of the late 1900s would astonish most Californians today. Because of fire suppression, trees in current forests live alongside six to seven times as many trees as their ancestors did — competing for less water amid drier and hotter conditions.

Giving 1,200-pound cows access to one of California's most fragile and biologically rich ecosystems seems a strange way to protect its threatened and endangered species.

Study of a rice field in Asia found that selective breeding and management decisions maintained crop yields despite climate changes, but those interventions weren’t enough to increase production to meet global demand, according to a paper from University of California, Davis.

Pima cotton is the predominant variety of cotton grown in California. It’s ideal for making premium fabrics for clothing and bed sheets. But Fusarium wilt disease, caused by a soil-borne fungus, can devastate a cotton crop. It’s responsible for crop losses in several production regions in the U.S. and worldwide.
