Plant Biologists Identify Promising New Fungicides

A promising new fungicide to fight devastating crop diseases has been identified by researchers at the University of California, Davis. The chemical, ebselen, prevented fungal infections in apples, grapes, strawberries, tomatoes and roses, and improved symptoms of pre-existing fungal infection in rice.

How Tomato Plants Use Their Roots to Ration Water During Drought

Plants have to be flexible to survive environmental changes, and the adaptive methods they deploy must often be as changeable as the shifts in climate and condition to which they adapt. To cope with drought, plant roots produce a water-repellent polymer called suberin that blocks water from flowing up towards the leaves, where it would quickly evaporate. Without suberin, the resulting water loss would be like leaving the tap running.

How Sunflowers See the Sun

Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers “see” the sun to follow it? New work from plant biologists at the University of California, Davis, published Oct. 31 in PLOS Biology, shows that they use a different, novel mechanism from that previously thought.

Night at the Conservatory Lecture Series

Join us at 6pm on the second Thursday for a plant related talk given from members of the conservatory community. FREE! All are welcome to attend. Snacks and drinks will be provided however space is going to be limited, so try and come early.  Conservatory will be open for viewing.

A Gift Grows On: The Legacy of Katherine Esau

In 1988, a 90-year-old alumna and former faculty member gave $648,000 to UC Davis to establish an endowment that would fund plant research fellowships in perpetuity. Still driving discovery today, her gift demonstrates the power of an endowment to benefit the world for generations.

Circadian Clock Controls Sunflower Blooms, Optimizing for Pollinators

An internal circadian clock controls the distinctive concentric rings of flowering in sunflowers, maximizing visits from pollinators, a new study from plant biologists at the University of California, Davis, shows. The work was published Jan. 13 in eLife.

Rice Breeding Breakthrough to Feed Billions

An international team has succeeded in propagating a commercial hybrid rice strain as a clone through seeds with 95% efficiency. This could lower the cost of hybrid rice seed, making high-yielding, disease resistant rice strains available to low-income farmers worldwide. The work was published Dec. 27 in Nature Communications.

First Complete Structures of Plant Respiratory Proteins

Back-to-back papers in the Dec. 29 issue of Nature Plants report the first complete protein structures for plant respiratory supercomplex I+III₂. Obtaining these structures helps researchers understand basic plant biology, as well as stress responses and how biofuel crops might grow more rapidly.

Understanding Growth Regulation by Protein Degradation in Trees for Bioenergy

The U.S. Department of Energy is funding a project at the UC Davis College of Biological Sciences to study the function of genes that regulate growth and wood formation in poplar trees. The three-year, $2.5 million project is led by Nitzan Shabek, assistant professor in the UC Davis Department of Plant Biology together with Andrew Groover at the USDA Pacific Southwest Research Station in Davis and Justin Walley, Iowa State University.
