6-(gamma,gamma-Dimethylallylamino)Purine As A Precursor of Zeatin.

Abstract

A 6-(gamma,gamma-dimethylallylamino) purine-like compound was found in the culture medium of Rhizopogon roseolus, which had been shown earlier to synthesize zeatin. The role of 6-(gamma,gamma-dimethylallylamino) purine as a precursor of zeatin was studied. Rhizopogon was furnished with 6-(gamma,gamma-dimethylallylamino) purine-8-(14)C. Cochromatography, oxidation studies with potassium permanganate, and bromination indicated that labeled zeatin ribonucleoside was isolated from the medium. The fungus also incorporated labeled adenine, hypoxanthine, and 4-amino-5-imidazole carboxamide into zeatin ribonucleoside.
