Scientists Unlock Key to Drought-Resistant Wheat with Longer Roots

Scientists Unlock Key to Drought-Resistant Wheat with Longer Roots

An international group 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, with the resulting plants producing more biomass and higher grain yield.

The study published in the journal Nature Communications provides novel tools to modify wheat root architecture to help the plants withstand low water conditions, said Gilad Gabay, a postdoctoral researcher in the Department of Plant Sciences at UC Davis and the paper's first author. Little has been known about the genes affecting the root structure of wheat. The discovery of the OPRIII gene family and that different copies of these genes affect root length is a significant step, said Distinguished Professor Jorge Dubcovsky, the project leader in the lab where Gabay works.

What is Regenerative Agriculture?

Video: What is Regenerative Agriculture?

Regenerative agriculture can help us fight the impacts of climate change while restoring ecosystems, water and carbon cycles, and spurring economic growth. But what is regenerative agriculture? NRDC wanted to learn more from the farmers and ranchers doing the work, so we interviewed 113 growers, and they told us what regenerative agriculture means to them. We learned that regenerative agriculture goes beyond farming practices. Produced in collaboration with Kiss the Ground, this video summarizes what regenerative agriculture is, as told by the farmers and ranchers we interviewed.
