Plants can better tolerate drought and other stressors with the help of natural microbes, 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.

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.
Microbes and their benefits to plants is a burgeoning field, and Doty’s lab in the last 15 years has explored many different aspects of this mutual symbiosis. Earlier this year, her team demonstrated that microbes in plants help them grow in otherwise inhospitable environments — essentially serving as a natural fertilizer. Naturally providing nutrients and boosting drought resistance could make it easier and more environmentally friendly to grow grain and vegetable crops, fruit and nut trees, and even keep golf courses looking lush and green without using excess amounts of water and chemical fertilizer.
