Two ideas have been proposed to explain the eversion of the polar filaments.
2.
The polar filament is important in species classification.
3.
There are also three polar capsules, each of which contains a coiled polar filament.
4.
Apart from forming non-polar filaments, septins associate with cell membranes, actin filaments and microtubules.
5.
These complexes then associate to form non-polar filaments, filament bundles, cages or ring structures in cells.
6.
This structure may function as a stopper, its digestion in the alimentary tract possibly triggering the discharge of the polar filaments.
7.
Spores germinate quickly after entering the insect, and the epithelial cells of the ventriculus are infected when the vegetative stage is introduced by way of the hollow polar filament.
8.
The polar filament is coiled along the inner wall of the polar capsule, and is capable of rapid extrusion, during which it everts " inside-out ".
9.
Ovcharenko instated the novel genus " Cucumispora " to describe the presence a specific anterior structure to aid in attachment to a susceptible host, specific arrangements of isofilar polar filaments, substantial diplokaryon, and vacuole structure.
10.
In some specied of Ceratomyxa, the polar filament forms a straight basal section, which the rest of the filament coils around, while in the genus Sphaeromyxa, the filament is folded in a zig-zag arrangement, rather than being coiled.
