Mastigont system
The Mastigont system is a series of structures found in several
basal bodies and several other structures composed of fibrils. Their function is not fully understood.[1] The system is studied and visualised mainly through techniques such as plasma membrane extraction, high-voltage electron microscopy, field emission scanning electron microscopy, the cell-sandwich technique, freeze-etching, and immunocytochemistry
.
Composition
The main structures that compose the Mastigont system include:[2]
- the pelta-axostyle system, made of karyokinesis. The pelta is a microtubular structure that holds the flagellar canal.
- The costa, a rootlet; it supports flagellar movements and provides an anchoring system for the nucleus and Golgi.
- The parabasal and sigmoid filaments;
- Other filaments.
