Legumes’ symbiotic interaction with nitrogen-fixing bacteria supplies the plant with nitrogen. Many important crop plants, however, cannot establish these symbioses and, thus, agriculture depends on externally applied fertilizers. It was surprising, then, that Liang et al. found that several nonleguminous plants—including Arabidopsis, tomato, and corn—were able to respond to the same Nod factors that initiate the microbial symbiosis in soybean.
