The effect of inhibitors of protein and nucleic acid synthesis on nucleolar size and enzyme induction in Jerusalem artichoke tuber slices.

The effects of various inhibitors of protein and nucleic acid synthesis on the development of invertase activity and increased nucleolar volume in discs excised from tubers of artichoke tissue are compared. The results are discussed with reference to the current theories relevant to the action of the inhibitors and to the nature of the increase in nucleolar volume.
