Effect of GA on stage-specific development of P. falciparum. Ring-stage synchronized P. falciparum 3D7 cultures were continuously exposed for 24 h or 48 h with the same concentrations of GA as in Fig. 5, and the stained parasites were morphologically characterized as ring (R), trophozoite (T), and schizont (S). The pyknotic changes (P) were also scored at the same time. Numbers are average of three experiments with less than 15% variation.
