Abstract
Plant hormones from biomass of the purple non-sulfur bacterium Rhodosp irillum rubrum were isolated for the first time. These compounds show high physiological activities (300-330%) in the cytokinin bioassay. Al l three detected cytokinins are adenine derivatives, according to spec tral analysis. One of them was identified as trans-2-butenylamino)-9-b eta-D-ribofuranosylpurine (zeatinriboside) as shown by thin-layer chro matography and reversed-phase high-performance liquid chromatography. The possible functions of bacterial cytokinins are also discussed.
