Cytokinin Utilization by Adenine-Requiring Mutants of the Yeast Saccharomyces cerevisiae1

RESUMO
By monitoring the growth of several adenine auxotrophs of the yeast Saccharomyces cerevisiae on cytokinin-supplemented media, we have demonstrated that this organism can utilize some of these derivatives as a source of adenine. Growth of a mutant lacking adenylosuccinate synthetase suggests that the conversion of cytokinins to adenine does not involve a hypoxanthine intermediate and may be catalyzed by an enzyme analogous to cytokinin oxidase.
