California produces 99% of the nation’s pistachios, generating nearly $3 billion in economic value in the state. But pistachios have been slightly understudied in part because of the lack of a high-quality map of their DNA. University of California, Davis, researchers have now generated the most comprehensive genome sequence of the pistachio, allowing plant breeders to create better — perhaps more nutritious — varieties. They’ve also detailed how pistachio nuts develop, which will help farmers manage their crop more sustainably.

Warming weather, water scarcity and a loss of winter fog threaten pistachio production in California’s southern San Joaquin Valley, potentially disrupting one of the state’s most valuable crops.  

The University of California, Davis, is enhancing and expanding its Pistachio Breeding Program after a generous gift from philanthropist and pistachio farmer Rod Stiefvater, who is donating more than $335,000 over three years to develop new rootstocks that thrive under changing climate conditions. 

Construction officially began on the Lynda and Stewart Resnick Center for Agricultural Innovation Wednesday with a groundbreaking event celebrating the future $64.4 million facility at the University of California, Davis.
