Cytokinins in the Soluble RNA of Plant Tissues

Abstract
The cytokinin, N 6 -(Δ 2 -isopentenyl)adenosine occurs in the soluble RNA of yeast and mammalian tissue and has now been detected in plant soluble RNA. A hydroxylated derivative of this cytokinin 6-( cis -4-hydroxy-3-methylbut-2-enylamino)-9-β-D-ribofuranosylpurine has also been identified as a constituent of plant soluble RNA.
