ISOPENTENYLADENINE (i6Ade) and closely related derivatives occur naturally either as free bases or as constituents of tRNA1,2. Although these cytokinins have been detected in various organisms, it is still not clear whether they are produced by the degradation of tRNA or whether they are synthesised by some pathway not involving tRNA. A spore germination inhibitor, discadenine, isolated from Dictyostelium discoideum was found to be an i6Ade derivative with a 3-amino-3-carboxypropyl group in the… CONTINUE READING
