The devastating effects of drought are expected to increase in severity and frequency in the coming years. To protect the world`s food supply, scientists turn to genetic engineering. Now, a team of researchers has discovered how changes in the microbiome-the ecosystem of bacteria and other microorganisms attached to the roots of plants and in the soil surrounding it-may improve drought tolerance in plants.
