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.

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.
