Abstract: The identification of the maize Bx1 gene involved in benzoxazinone biosynthesis activity is described. This Bx1 gene, as well as other benzoxazinone biosynthesis genes, provide valuable tools for the production of plants with enhanced expression profiles of bezoxazinone synthesis, and therefore, resistance to insect infestation.
