Pathway : Benzoxazinoid biosynthesis

Identifier  00402 Description  Benzoxazinoids hydroxamic acids are plant secondary metabolites that serve as important factors for host resistance against microbial pathogens and insects and for allelopathic effects They are found in grass family and some eudicot families The predominant benzoxazinoids are DIBOA and its 7-methoxy derivative DIMBOA, which are stored as glucosides in vacuoles In maize, benzoxazinoid biosynthesis branches off from tryptophan biosynthesis at indole-3-glycerol phosphate, which is converted to indole by indole-3-glycerol phosphate lyase, BX1 Subsequently four cytochrome P450 monooxygenases BX2-BX5 catalyze the introduction of four oxygen atoms into the indole moiety, yielding DIBOA After glucosylation by UDP-glucosyltransferase BX8/BX9, the glucoside is further modified by hydroxylation and O-methylation at C-7 to form DIMBOA-glucoside
