Identification and heritability of fumonisin insensitivity in Zea mays

Most domesticated maize and wild teosintes (Zea mays species) are highly sensitive to fumonisin B1, a phytotoxic polyketide produced by fungi pathogenic to maize. In a survey of genetically diverse maize landraces, high insensitivity to fumonisin B1 was identified and shown to be an inheritable trait.
