Scientists Unlock Key to Drought-Resistant Wheat Plants with Longer Roots

Growing wheat in drought conditions may be easier in the future, thanks to new genetic research out of the University of California, Davis.

An international team of scientists found that the right number of copies of a specific group of genes can stimulate longer root growth, enabling wheat plants to pull water from deeper supplies. The resulting plants have more biomass and produce higher grain yield, according to a paper published in the journal Nature Communications.

Brummer honored by alfalfa conference

E. Charles Brummer has been honored for bettering alfalfa science and cultivation by the North American Alfalfa Improvement Conference. Brummer, a professor in the Department of Plant Sciences, is the director of the UC Davis Plant Breeding Center and involved in researching a wide range of crops for forage, grain and fiber.

Lettuce: Michelmore Lab seeks genetic resistance to fungus, bacteria

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.

FFAR, Benson Hill grant $1,855,162 to UC Davis to study the Sierra Mixe corn variety’s remarkable ability to glean nitrogen from atmosphere

The Foundation for Food & Agriculture Research, or FFAR, has awarded a Seeding Solutions grant to the University of California, Davis to study how the microbial community hosted by the Sierra Mixe corn variety provides atmospheric nitrogen to the plant. Seeding Solutions grants are awarded annually in six different challenge groups recognized by the FFAR, with this one falling under “Next Generation Crops.” The grant was matched by Benson Hill for a total investment of $1,855,162

Lettuce Mitochondrial Genome is Like a Chopped Salad

Mitochondria in cells generate energy for the cell and play roles in metabolism and programmed cell death. Not all mitochondria are the same — plant mitochondria are quite different from animal mitochondria. New research from the UC Davis Genome Center and partnering universities shows just how different.
