Louise Ferguson organized a two-day visit to Washington, D.C., for fellows in the Leadership Academy of the American Society of Horticultural Science.

Researchers from the UC Davis Department of Plant Sciences attended the 39th biennial Rice Technical Working Group conference, held Feb. 20-23 in Hot Springs, Ark. The conference is hosted by the University of Arkansas System Division of Agriculture.

Jorge Dubcovsky and researchers in his lab have been recognized for providing basic genetic information about wheat and improved germplasm that is being used by scientists around the world to improve “the staff of life.” Those efforts are bringing new varieties of wheat to farmers adapting to new conditions. For his leadership in those efforts, Dubcovsky was awarded the Frank N. Meyer Medal for Plant Genetic Resources, and a $2,000 prize, at the recent annual meeting of the Crop Science Society of America.

Maeli Melotto and her team at the UC Davis Department of Plant Sciences are looking for strains of lettuce that are genetically stronger at resisting bacteria that can make people sick. Their work has led to the identification of a gene that could play a role in the plant’s susceptibility to E. coli, a bacterium that causes potentially lethal intestinal illness.

Albert Fischer, a professor emeritus of weed ecophysiology in the UC Davis Department of Plant Sciences, was recently named recipient of the Outstanding International Achievement Award by the International Weed Science Society.

Shortly after the award was announced, Fischer passed away on Nov. 22 in Davis, Calif. He was 72. Former student Whitney Brim-DeForest accepted the award on Fischer’s behalf at the society’s quadrennial meeting Dec. 8 in Bangkok.

Downy mildew makes those dry, tan-colored spots on spinach leaves -- a problem especially in organic cultivation. Growers have safety measures to ensure spinach is attractive, tasty and safe, but pathogens keep coming up with new ways to get around them, said Allen Van Deynze, associate director of the UC Davis Plant Breeding Center, directed by Charlie Brummer.

As common crop diseases such as downy mildew, Fusarium and corky root evolve, Richard Michelmore and members of his lab look for the genetic basis of new variations and for genes in lettuce that can resist them. They hope to breed those qualities into existing cultivars that already stand up to multiple diseases.

Josh Hegarty, a postdoctoral researcher in the Dubcovsky Lab in the Department of Plant Sciences at the University of California, Davis, is leading a project to develop commercial varieties of triticale to be grown for forage and feed. The National Institute of Food and Agriculture, or NIFA, is granting a $300,000 investment as part of their Agriculture and Food Research Initiative.

“Ice cream in the making” – this is the unusual designation given to alfalfa by Dan Putnam, a Cooperative Extension Specialist in the Department of Plant Sciences at the University of California, Davis.

Alfalfa is often overshadowed by California’s more famous vegetable and fruit crops, like nuts and wine, despite the key roles it plays for our food systems. It’s a highly productive crop that serves as the basis for milk, cheese, leather, honey and wool production. In other words, what lies behind the carton of ice cream on the refrigerator shelf is a field of alfalfa.
