WebBiosynthesis of Cytokinins: Two mechanisms have been proposed for cytokinin biosynthesis, one leading to tRNA cytokinins and the other to free cytokinins. … WebCytokinins are prenylated derivatives of adenine. In zeatin, which is the most common cytokinin, the amino group of adenine is linked with the hydroxylated isoprene residue in the trans-position (Fig. 19.11).In other cytokinins benzyl derivatives, sugars, or sugar phosphates are attached to the adenine. Cytokinins enhance plant growth by stimulating …

WebSep 7, 2010 · Induction of IAA Biosynthesis by Cytokinin. (A) The de novo IAA biosynthesis rate was analyzed in specific tissues after incubation of 10 DAG Arabidopsis seedlings in a medium containing 30% 2 H 2 O. Seedlings were divided into (a) apex and young developing leaves (leaf 3 and smaller), (b) the first two true leaves, and (c) the … WebCytokinins (CKs) are a complex group of compounds. The complexity of CKs is not just present at the level of chemical structures, but as a family of compounds. CKs occur in plants as nucleotides, nucleosides (ribosides) that are produced during de novo biosynthesis, free bases, and conjugates that are in stored/inactivated forms. Almost all … WebApr 30, 2024 · Cytokinin is an important regulator of symbiotic nodule development. Recently, KNOTTED1-LIKE HOMEOBOX 3 transcription factor (TF) was shown to regulate symbiotic nodule development possibly via the activation of cytokinin biosynthesis genes. chuck mangione live in concert
