FIG 7.

Prolonged incubation in IAA results in multiple defects in the TgMAPK2AID parasite ultrastructure. Shown are transmission electron micrographs of intracellular TgMAPK2AID parasites in the absence of IAA (A and B), with 6 h of growth in IAA (C and D), or with 20 h of growth in IAA (E to H). *, daughter buds; Go, Golgi apparatus; Ap, apicoplast; Mt, mitochondria; RB, residual bodies. Bars = 1 μm. Note that 100% of parasites treated for 20 h with IAA had overduplicated apicoplasts, and 35% ± 5% had overduplicated Golgi apparatus; neither phenotype was observed in untreated parasites.
