Beschreibungen/Notizen

• Indications are presented that the heterocysts of a member of the Rivulariaceae germinate in NO3 free medium containing low concentrations of NH4Cl and glucose. Growth occurred regularly in the absence of combined nitrogen sources (NH4, NO3), suggesting N2 fixation. Phosphate regulates hormogonia release, perhaps indirectly via an influence on differentiation of heterocysts.
