Change in concentration of secondary metabolites- DIMBOA and phenolic acids in leaves of Bt corn
转Bt基因玉米叶片次生代谢物DIMBOA和酚酸类物质含量的变化

Cyclic hydroxamic acids and phenolic acids are among important secondary metabolites of corn plant. These materials and their derivatives have implications for the resistance of the plants to herbivores, pests and pathogens. The content of leaf DIMBOA (2,4-dihydroxy-7-methoxy y-2H-1,4-benzoxazin-3-one) and phenolic acids in Bt corns 34B24, G30, Nongda 61, and 1426×1482 were quantified by HPLC. The content of leaf DIMBOA in Bt corns of 34B24 and G30 were significantly lower than that in their corresponding n...
