Figure 6.

Changes in SPS activity in noninductive medium before and after the addition of an inducing concentration of cytokinin. In the absence of TE induction, SPS activity remained undetectable. The culture was allowed to deplete its starch before the cytokinin was added to certain aliquots at 150 h to produce the late-induced culture. Percentages beside the data points for the late-induced culture are the percentage of TEs among all cells counted at that time point. All unlabeled data points correspond to 0% TEs.
