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. WebOct 5, 2007 · The chemical structure of three cytokinins is shown on top: trans-zeatin (tZ), ... Cytokinin signaling, in turn, represses transcription of AHP6. Lack of AHP6 function causes ectopic cytokinin signaling, leading to pattern defects in vascular tissue . Thus, the presence of AHP6 may limit the number of cells responding to cytokinin and, thereby ...
