Poplars given microbes (top) survived better in drought conditions, compared with plants with no added microbes (bottom).

With California in its fifth year of severe drought and many western states experiencing another year of unusually dry conditions, plants are stressed.

Agricultural crops, grasses and garden plants alike can get sick and die when factors such as drought and excess sun force them to work harder to survive.

Now, plants can better tolerate drought and other stressors with the help of natural microbes, University of Washington research has found. Specifically, plants that are given a dose of microbes stay green longer and are able to withstand drought conditions by growing more leaves and roots and using less water.

“Plants are less stressed if they have these natural microbes,” said senior author Sharon Doty, a UW professor of environmental and forest sciences. “They will help plants deal with environmental challenges, especially with climate change.”

The findings were published online this month in the journal Current Plant Biology.
