Fig. 2.
Endogenous cytokinin and auxin profiles in selected cyanobacterial and algal species. Cytokinin profiles were determined in the early stationary growth phase and are based on conjugation status/physiological function (A) and the chemical structure of the purine ring (B). Endogenous levels of both cytokinins and auxins (C) are expressed in pmol g−1 FW. Abbreviations of selected cyanobacterial and algal representatives are given in Table S1.
