Phaseolus vulgaris L. plants were supplied through the root with [8-14C]benzylaminopurine ([14C]BA). Collections of root, apex, and leaves were made 8 and 48 hours after labeling; ethanolic extracts of tissues were purified and subjected to thin layer chromatography on silica gel and/or cellulose powder.From [14C]BA at least two different metabolites originate, the BA riboside and ribotide. The balance among [14C]BA, the riboside, and the ribotide changed in time. The [14C]BA riboside was detected as the only labeled compound in the xylem sap collected from the stem.

Abstract
Phaseolus vulgaris L. plants were supplied through the root with [8-14C]benzylaminopurine ([14C]BA). Collections of root, apex, and leaves were made 8 and 48 hours after labeling; ethanolic extracts of tissues were purified and subjected to thin layer chromatography on silica gel and/or cellulose powder.From [14C]BA at least two different metabolites originate, the BA riboside and ribotide. The balance among [14C]BA, the riboside, and the ribotide changed in time. The [14C]BA riboside was detected as the only labeled compound in the xylem sap collected from the stem. The biological function of BA riboside and ribotide is discussed.File in questo prodotto:
