Op. Serdyuk et al., 4-HYDROXYPHENETHYL ALCOHOL - A NEW CYTOKININ-LIKE SUBSTANCE FROM THE PHOTOTROPHIC PURPLE BACTERIUM RHODOSPIRILLUM-RUBRUM 1R, FEBS letters, 365(1), 1995, pp. 10-12
Three compounds with cytokinin activity have been isolated from the me
dium of Rhodospirillum rubrum grown photosynthetically, Two N-6 aminop
urine cytokinins revealed in the medium were identical with those obta
ined from R. rubrum cells previously, The third compound with cytokini
n activity in Amaranthus caudatus bioassay proved to be a simple pheno
lic compound with elemental composition C8H10O2. This cytokinin-like s
ubstance according to absorption spectra, mass spectrometry and H-1 NM
R spectra data was identified as 4-hydroxyphenethyl alcohol.
