title: Cytokinin Secretion by Frankia sp. HFP ArI3 in Defined Medium.
abstract: Frankia sp. HFP ArI3 (host plant Alnus rubra Bong.) was grown in defined medium and the culture solution was analyzed for the presence of various cytokinins and related compounds. N(6)- (Delta(2)-isopentenyl) adenosine was the only cytokinin detected by both high performance liquid chromatography and gas chromatography-mass spectrometry, at levels of approximately 1 ng/ml culture medium.
