A corn plant knows how to find water in soil with the very tips of its roots, but some varieties, including many used for breeding high-yielding corn in the U.S., appear to have lost a portion of that ability, according to a Stanford-led study. With climate change increasing droughts, the findings hold potential for developing more resilient varieties of corn.
The study, published in the journal Science, uncovers genetic mechanisms behind root “hydropatterning,” or how plant roots branch toward water and avoid dry spaces in soil. In particular, the researchers discovered that ethylene, a plant hormone known to help bananas ripen, also influences how roots grow to seek water.
