As we have microbial communities in our guts, on our skin, and in various other places in and on our bodies, plants also have beneficial microbial symbionts around their roots, on their leaf surfaces, and even inside their tissues. These microbes can be bacteria, fungi, or other, and can help plants gather nutrients, resist diseases or pests, and other things.

In this study, some fungi living in grain plants—called endophytes, or "inside plants"—can help wheat tolerate drought and grow better with less water. Studying this system could lead to breakthroughs in wheat farming, all thanks to microbes.
