Abstract

[(3)H] Zeatin was supplied to Zea mays L. seedlings with roots excised; the metabolites identified were adenosine-5'-phosphate, adenosine, adenine, and 7-glucosylzeatin (a minor metabolite). The principal metabolites formed from zeatin by the roots of intact Z. mays seedlings were adenosine-5'-phosphate, zeatin riboside-5'-phosphate, zeatin riboside, adenine, adenosine and an unknown compound termed Y. This was isolated and identified as 9-glucosylzeatin. This glucoside also appeared to form from zeatin in cultured embryonic tissue of Z. mays.
