ABSTRACT
The characterization of the Cel mutants we isolated also re sulted in the discovery of genes exerting pleiotropic effects on
FIGURE 1 Induction of cellulose synthesis in a Cel mutant of A. xylinum ATCC 10245 by tetracycline. The mutant used in this experiment was a spontaneous Cel mutant called C e ll. Tetracycline was added to an exponentially growing cell culture at time zero (filled circles). The open circles represent an aliquot of the cul ture where no tetracycline was added. For other technical details, see Ref. 2.
