The food additive aminoglycoside 3′-phosphotransferase II may be safely used in the development of genetically modified cotton, oilseed rape, and tomatoes in accordance with the following prescribed conditions:
（a） The food additive is the enzyme aminoglycoside 3′-phosphotransferase II （CAS Reg. No. 58943–39–8） which catalyzes the phosphorylation of certain aminoglycoside antibiotics, including kanamycin, neomycin, and gentamicin.
（b） Aminoglycoside 3′-phosphotransferase II is encoded by the kan rgene originally isolated from transposon Tn5of the bacterium Escherichia coli.
?。╟） The level of the additive does not exceed the amount reasonably required for selection of plant cells carrying the kan rgene along with the genetic material of interest.
