Endosymbiosis and Cellular Tolerance in the Hawaiian Soft Coral Sarcothelia Edmondsoni Verrill
- 58 Downloads
The relationship between the soft coral Sarcothelia edmondsoniVerrill and its symbiotic algae is considered as an early instance of cellular tolerance which can be disturbed by a variety of adverse conditions. The algal cells lie in vesicles deep within the endodermal cells of the host and are not subject to digestion. Their expulsion appears to be a reverse translocation to the distal end of the host cell and escape by a form of reversed phagocytosis resembling secretion. The cellular mechanisms involved are not clear.
