Detail Short Term Metabolism of Urea and Purime Cytokinins (in Plant Physiol. (1972) 49, 506-513) Bibliografi Author: Dyson, William H. ; Fox, J. Eugene ; Mcchesney, James D. Topik: Cytokinin Benzyladenine (BA); Soybean; 6- benzylamino 9-ß-D- ribofuranosylpurine 5'- monophosphate (BAMP) Bahasa: (EN )     Tahun Terbit: 1972     Jenis: Article - diterbitkan di jurnal ilmiah internasional Fulltext: metb urea cyto.pdf (1.13MB; 0 download) Abstract Approximately 20 to 25% of the cytokinin benzyladenine (BA) taken up by soybean tissues in culture is converted to a stable, long-lived derivative which contains BA as part of its structure. This derivative may be metabolically related to 6- benzylamino 9-ß-D- ribofuranosylpurine 5'- monophosphate (BAMP). In in vivo incubations of 2 hours or less, we recover only BA, benzyladenosine, and BAMP. Benzyladenosine never accounts for more than 10% of the total radioactivity while BAMP builds up to about 20% of the total within 2 to 4 hours. After this period it begins to disappear, and a new, nidentified substance arises at a rate which roughly parallels the loss of BAMP. After about 48 hours this substance, which has good cytokinin activity, accounts for some 20 to 25% of the total radioactivity and persists at this level for at least 60 days. In the meantime the remainder of the BA, as well as benzyladenosine and BAMP, disappear completely. In addition, evidence is presented which suggests that the urea cytokinins are not active as such but first are metabolically transformed into other substances.
