Studies on Ailanthus altissima cell suspension cultures. Uptake of L-[methyl-(14)C]methionine and incorporation of label into 1-methoxycanthin-6-one.

Time-course studies of the uptake of L-[methyl (14)C]-methionine have shown rapid uptake by Ailanthus altissima cells when fed at weekly stages throughout the growth cycle. The radio-label from [(14)C]-methionine was shown to be incorporated into 1-methoxycanthin-6-one with the highest level of incorporation being achieved with cells fed late in the growth phase.
