Tropical Plants Beat Drought by Interacting with Specific Microbes

Researchers from the University of Arizona and the Environmental Molecular Sciences Laboratory, a Department of Energy user facility, discovered that that plants can maintain specific microbe partnerships during times of drought, revealing a new level of resilience.

Soil microbes help plants cope with drought, but not how scientists thought

In a multi-generation experiment, researchers from the College of Agricultural, Consumer and Environmental Sciences (ACES) found microbes helped plants cope with drought, but not in response to plants’ cries for help. Instead, the environment itself selected for drought-tolerant microbes. And while those hardy microbes were doing their thing, they just happened to make plants more drought-tolerant, too.
