UCLA Research Makes Possible Rapid Assessment of Plant Drought Tolerance

UCLA life scientists, working with colleagues in China, have discovered a new method to quickly assess plants’ drought tolerance. The method works for many diverse species growing around the world. The research, published in the journal Methods in Ecology and Evolution, may revolutionize the ability to survey plant species for their ability to withstand drought, said senior author Lawren Sack, a UCLA professor of ecology and evolutionary biology.

“This method can be applied rapidly and reliably for diverse species across ecosystems worldwide,” he said of the federally funded research by the National Science Foundation. (more…)

New research by UCLA life scientists could lead to predictions of which plant species will escape extinction from climate change.

Droughts are worsening around the world, posing a great challenge to plants in all ecosystems, said Lawren Sack, a UCLA professor of ecology and evolutionary biology and senior author of the research. Scientists have debated for more than a century how to predict which species are most vulnerable.

Sack and two members of his laboratory have made a fundamental discovery that resolves this debate and allows for the prediction of how diverse plant species and vegetation types worldwide will tolerate drought, which is critical given the threats posed by climate change, he said. (more…)
