Scientists Sequence Walnut GenomeApril 3, 2019
According to Dan Kluepfel, a USDA-ARS scientist and principal investigator of the walnut-rootstock development project, they chose to cross the widely used English walnut with the wild Texas black walnut because of its native resistance to several soil-borne diseases and root nematodes, which are serious pests of walnut in California.
The scientists produced complete genome sequences of the two walnut species in the time normally required to produce the sequence of one genome. These genome sequences will now help researchers identify genetic markers that can be used to develop new varieties with improved pathogen and pest resistance.
