Researchers at UC Davis, the Boyce Thompson Institute (BTI) at Cornell University, the University of Minnesota and Iowa State University have received a four-year, $10.3 million “Insect Allies” award from the Defense Advance Research Projects Agency (DARPA) to engineer viruses carried by insects that can help in combatting disease, drought, and other yield-reducing stresses in maize.

Understanding how live pigs are traded between villages and backyard farmers can help health agencies better understand how devastating swine diseases spread, according to a study published recently in the journal PLOS ONE.

The bioinformatics company Illumina has donated a state-of the-art DNA sequencer to a global plant-breeding effort to fight malnutrition and poverty in Africa by improving the continent’s traditional crops. UC Davis is partnering in the African Orphan Crop Consortium, which is working to map and make public the genomes of 101 indigenous African foods.
These “orphan” crops are crucial to African livelihood and nutrition, but have been mostly ignored by science and seed companies because they are not traded internationally like commodities such as rice, corn, and wheat.

Goals for carbon reduction from sequestration in soils set in the 2015 Paris Agreement are not feasible, according to an international team of climate scientists. Regardless of whether the U.S. remains part of the Paris climate accord, scientists at the University of California, Davis, are developing additional agricultural methods to offset increases in atmospheric greenhouse gases, thereby reducing the potential for global warming.
In this episode of our Three Minute Egghead podcast, UC Davis plant biologist Siobhan Brady talks about her work on roots.
Roots are the key innovation that allowed plants to conquer the land. They allow a plant to explore its environment, seeking out water and nutrients. A cell type within roots called xylem transports water and also provides support for land plants, allowing them to grow swiftly like a field of corn or reach towering heights of a sequoia.

Rice farmers seeking to protect their crops from pests without high dependency on pesticides may want to consider the sustainable pest management practice known as the “banker plant system.”
First-of-its-kind research, published in Scientific Reports by a nine-member team including UC Davis agricultural entomologist Christian Nansen, indicated that attracting alternative hosts for parasitoids of rice insect pests can help protect a rice crop. The players: a grass species, a planthopper, and an egg parasitoid.

At one time, rice farmers in Haiti could meet demand for all Haitians. Today, national rice production accounts for less than one-fifth of consumption. Increasing the amount of rice farmers can grow could be key to reducing poverty and improving food security in Haiti, especially among the 1.6 million people who live in the Artibonite Valley, the largest rice-producing region in the nation.

Scientists at the University of California, Davis have discovered that DNA sequences thought to be essential for gene activity can be expendable. Sequences once called junk sometimes call the shots instead.
Professor Alan Rose has been working for over two decades to unravel a mechanism called “intron-mediated enhancement.” I’m a graduate student in Rose’s lab, and we made an exceptional discovery in an unexceptional plant called Arabidopsis thaliana, or thale cress.
Represents Most Successful Group of Flowering Plants

Today (April 12), UC Davis researchers announced in Nature Communications that they have unlocked a treasure-trove of genetic information about lettuce and related plants, releasing the first comprehensive genome assembly for lettuce and the huge Compositae plant family.
Garden lettuce, or Lactuca sativa, is the plant species that includes a salad bar’s worth of lettuce types, ranging from iceberg to romaine. With an annual on-farm value of more than $2.4 billion, it is the most valuable fresh vegetable and one of the 10 most valuable crops, overall, in the United States.

Spring is in the air in California’s Central Valley. Birds are bathing in puddles that dot the landscape, and bats are swooping in and out of streetlights at dusk. Both groups of wildlife are feasting on bugs emerging after this winter’s epic rains.
The sight is a pleasant reminder of the abundance of wildlife that lives alongside us, performing tasks that inadvertently aid humans, such as natural pest control, pollination, and seed dispersal.
