Study Finds Indigenous Mexican Variety of Corn Captures the Nitrogen It Needs from the Air: Association with Nitrogen-Fixing Bacteria Allows the Corn to Thrive Without Fertilizer

Summary A corn variety growing in nitrogen-depleted fields derived 28–82 percent of nitrogen it needed from the atmosphere A sugar-rich, gel-like substance on the corn’s aerial roots, called mucilage, attracts bacteria and other microbes that fix nitrogen A team from UC Davis, UW–Madison, and Mars, Incorporated worked in partnership with indigenous community in Sierra Mixe…

Decoding the Redwoods: As Threats to California’s Giant Redwoods Grow, Their Salvation Might Be in Their Complex Genetic Code

[Summary from the Washington Post]: As California’s climate changes to one of extremes, the only coast redwoods on the planet are in peril. Just 5 percent of the redwoods that stood before 1849 are still alive. Scientists are mapping the coast redwood’s genome, a genetic code 12 times larger than that of a human being….

Genome Project Will Restore Health of Coast Redwood and Giant Sequoia Forests

Some trees are better at surviving drought, fire, pests, and diseases than other trees. By identifying the genes responsible for these adaptations, scientists can compile a scalable database that will aid resource managers as they plan long-term conservation strategies, particularly as the climate changes. Professor David Neale, UC Davis Department of Plant Sciences, showed in…

How Much Drought Can a Forest Take? Aerial Tree Mortality Surveys Show Patterns of Tree Death During Extreme Drought

Quick Summary Trees in the driest, densest forests are most vulnerable to dying in extreme drought Effects of extreme drought on forests can take years to surface High tree mortality rates likely to continue as drought effects linger Why do some trees die in a drought and others don’t? And how can we predict where…
