Abstract: The neomycin phosphotransferase gene has been widely used in transgenic plants as a type of marker genes.Since more and more genetically modified plants has been released for commercial use in recent years,the amount of transgenic foods containing neomycin phosphotransferase gene and its products will be increasing which leads to the public concern.FDA has allowed aminoglycoside 3’－ phosphotransferaseⅡ to be used in food plants for human consumption as a kind of food additives in 1994.The safety of neomycin phosphotransferase gene and aminoglycoside 3’－ phosphotransferaseⅡ in transgenic food plants has been extensively reviewed in this paper.
