An international team of researchers has mapped the “jumping genes,” formally named transposable elements, or transposons, in corn, says UC-Davis. “The discovery could ultimately benefit the breeding and production of maize, one of the world’s most important crops.”
A jury ruled that two former stars of the strawberry breeding program at UC-Davis violated an agreement with the university over control of the plants they developed while at the school.
The fourth year of unrelenting drought in California will cost the state agricultural economy $1.8 billion - 20 percent more than in 2014 - although farmers and their irrigation districts "are showing more resilience to the drought than many had anticipated," says a report by the UC-Davis Center for Watershed Sciences.
Topsoil and subsoil moisture levels continue to decline in the Pacific Northwest, where streamflows have shriveled to record or near-record lows, says the weekly Drought Monitor.
The mechanical tomato harvester, developed at UC-Davis, ranks as "a genuine breakthrough in the way that scientists thought about agricultural development," writes Ildi Carlisle-Cummins at Civil Eats.
Rice is a staple of half the world's population and also a potent emitter of greenhouse gases. But the Los Angeles Times reports that scientists say genetic engineering may help solve the grain's methane problem.
"On the agronomical trip to market, strawberries have lost some of their flavor," says Wired, noting the adjustments made over the decades to produce a bright-colored, slick-skinned, large-sized berry that is easy to pick and stays in condition.
California's farmers will have less irrigation water and will idle more cropland this year than they did last year, says a study by UC-Davis. It estimates direct agricultural losses of $1.8 billion, comprised of $1.2 billion in lower crop, livestock and dairy revenue and $600 million in higher costs to pump water from wells. "When we account for the spillover effect of agriculture on the state’s other economic sectors, the total cost of this year’s drought on California’s economy is $2.7 billion and the loss of about 18,600 full- and part-time jobs," say the authors.
With California headed for a fourth year of drought, the outlook for the growing season is grim. "But our situation is not hopeless," says Helene Dillard, dean of agriculture at UC-Davis.
A project at UC-Davis aims to develop a robotic cultivator that can do the equivalent of hand weeding, excising weeds as they sprout among rows of newly emerged crops.
