Nematocida parisii

Introduction to Microsporidia

The process of polar tube eversion during spore germination in microsporidia.
A) Shows a dormant spore containing a polar filament (black), nucleus (gray), polaroplast and posterior vacuole.
B) The posterior vacuole swells with water and ruptures the anchoring disk, allowing the polar filament to emerge through through spore cell wall.
C) Polar filament continues to to outward and evert.
D) Polar filament is fully everted and becomes a polar tube. Sporoplasm is squeezed into the polar tube.
E) Sporoplasm is moving through the polar tube.
F) Entire sporoplasm emerges from the polar tube while bound to the new membrane
