The severe chlorosis observed in the lower most of flooded sunflower plants (Helianthus annuus L. cv. Tall Single) may lie initiated by a reduction in the import of cytokinins by the stoot from the flooded root system. Experiment indicates that durin

The four cytokinins in the tRNA from Lupinus luteus L. seeds have been purified and identified as ribosyl-cis-zeatin, 2-methylthio-ribosylzeatin, (Δ (2)-isopentenyl)adenosine and 2-methylthio-N(6)-(Δ (2)-isopentenyl)adenosine. These structures have

A cytokinin in yeast cysteine tRNA has been isolated as the riboside and has been shown to have uv and mass spectra identical with those of synthetic 6-(3- methyl-2-butenylamino)-9-β - D -ribofuranosylpurine.

A method is described for the isolation of cytokinins from tRNA. The cytokinin active ribosides are recovered from enzymatic hydrolysates of tRNA by extraction with ethyl acetate. The extracts are fractionated by chromatography on Sephadex LH-20 colu

This distribution of cytokinin activity in tRNA species of Escherichia coli has been determined. Cytokinin activity was restricted to tRNA species recognizing codons with the initial letter U. The following have been shown to contain a cytokinin: tRN

Seed development in Pisum arvense L. cv. New Zealand Maple has been studied in relation to changes in level of total endogenous cytokinins. Growth of both the whole seed and the embryo is diauxic, having two phases of active growth separated by a lag
