Armstrong DJ, Scarbrough E, Skoog F: Cytokinins in Corynebacterium fascians Cultures: Isolation and Identification of 6-(4-Hydroxy-3-methyl-cis-2-butenylamino)-2-methylthiopurine. Plant Physiol. 1976 Dec;58(6):749-752.
In addition to the four cytokinins, 6-(3-methyl-2-butenylamino) purine, 6-methylaminopurine and the cis and trans isomers of 6-(4-hydroxy-3-methyl-2-butenylamino) purine, reported earlier from our laboratories, three cytokinin-active fractions have been obtained from the aqueous medium of 6-day-old Corynebacterium fascians cultures. One of these has been identified as 6-(4-hydroxy-3-methyl-cis-2-butenylamino)-2-methylthiopurine (2-methylthio-cis-zeatin, c-ms (2) io (6) Ade).The elution volumes of the other two fractions correspond to those of authentic 6-(4-hydroxy-3-methyl-2-butenylamino)-9-beta-d-ribofuranosyl-purine and 6-(3-methyl-2-butenylamino)-9-beta-d-ribofuranosylpurine, indicating the presence of trace amounts of these two ribonucleosides. |
