Cytokinin-Active Ribonucleosides in Phaseolus RNA: I. IDENTIFICATION IN tRNA FROM ETIOLATED PHASEOLUS VULGARIS L. SEEDLINGS 1
AUTOR(ES)
Edwards, Cynthia A.
RESUMO
The cytokinin-active ribonucleosides present in tRNA from etiolated Phaseolus vulgaris L. seedlings have been isolated and identified as cis-ribosylzeatin, 2-methylthio-ribosylzeatin, and N6-(Δ2-isopentenyl)-adenosine. The structures of the compounds were established on the basis of their chromatographic properties and the mass spectra of their permethylated and perdeuteromethylated derivatives. Cis-ribosylzeatin was the major cytokinin-active constituent of tRNA from this source.
