Max Planck Institute for Chemical Ecology Maize plants form special compounds derived from indole, the so-called benzoxazinoids. They are considered ecologically important because they act against a wide range of herbivores and reduce their feeding. Benzoxazinoids also exhibit antimicrobial properties and are thought to be involved in mediating plant-plant interactions. Their biosynthesis in maize has been known since the 1990s. Meanwhile, their biosynthetic pathway has been described in several grasses, but benzoxazinoids have also been found in other plant species.
