Cytokinins in macroalgae
Original language description
Thirty-one seaweeds were collected from the warmer KwaZulu-Natal coast and the cooler Cape waters ( South Africa). Plant material was extracted with 70% ethanol supplemented with deuterium labelled standards of all known isoprenoid cytokinins. The samples were then centrifuged and purified by combined DEAE-Sephadex3 octadecylsilica column and immunoaffinity chromatography and finally analysed for cytokinins by HPLC-linked mass spectrometry and a photodiode array detector. The cytokinin profiles were similar in all the macroalgae regardless of their taxonomy and growing locality. The main type of isoprenoid cytokinins present were zeatins with cis forms being more common than trans forms and isopentenyladenine (iP) derivatives. Only a few dihydrozeatin-type cytokinins were detected at very low levels in only nine species. Aromatic cytokinins were also present but at lower levels and were represented by benzyladenine (BA) and ortho- and meta-topolin derivatives. The topolins were present
