Fig. 4. — Metabolism of exogenously applied [³H]IAA in the cells of selected algal species. Radiolabelled [³H]IAA was applied to cultures of Chlorophyta species Stigeoclonium helveticum (A), Chlorella vulgaris (B), Microthamnion kuetzingianum (C) and Scenedesmus obliquus (D) in the early stationary growth phase. Bars represent distribution of radioactivity associated with individual metabolites in cells 0, 1, 2 and 6 h after [³H]IAA application. Products of [³H]IAA metabolism were analysed by HPLC coupled to an on-line radioactivity detector. Values are percentages of total extracted radioactivity in cells. RT, retention time.
