Fig. 1From: Identification and characterization of the first cytokinin glycosyltransferase from riceThe molecular structure of common active cytokinins. a The molecular structure of Isoprenoid CKs. There are four forms of Isoprenoid CKs, N6-(∆2-isopentenyl) adenine (iP), trans-zeatin (tZ), cis-zeatin (cZ), dihydrozeatin (DZ). b The molecular structure of Aromatic CKs. There are five forms of Aromatic CKs, ortho-topolin(oT),meta-topolin(mT),benzyladenine(BA),ortho-methoxytopolin(MeoT), meta-methoxytopolin(MemT)Back to article page
