Genetic Diversity of Wild North American Grapes Mapped

Wild North American grapes are now less of a mystery after an international team of researchers led by the University of California, Davis, decoded and catalogued the genetic diversity of nine species of this valuable wine crop.

The research, published in the journal Genome Biology, uncovers critical traits that could accelerate grape breeding efforts, particularly in tackling challenges like climate change, saline environments and drought.

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.
