Glucosinolates are important secondary metabolites in cruciferous plants, and their derivatives and degradation productions play a special function in plant defense reaction, formation of special flavor and cancer resistance. The glucosinolate biosynthesis is complex, including side chain elongation of amino acids, formation of the core glucosinolate structure and secondary modifications of the amino acid side chain, involving BCATs, MAMs, CYP79s, CYP83s, AOPs and other gene families. With gradual revelation of metabolic mechanism of glucosinol...
