Signals in the Paramecium Bursaria — Chlorella Sp. — Association

Part of the NATO ASI Series book series (volume 17)


Endosymbiotic associations of ciliates and coccoid chlorophyceae (Chlorella sp.) are frequently observed in freshwater habitats. They show different levels of organizational complexity, ranging from temporary associations with algal partners being digested to permanently stable units where algae are protected from host lytic enzymes by enclosure in special perialgal vacuoles. A stable system may be regarded as an entirely new organism on its own, showing many of the characteristics of a functional unit. It thus offers an excellent possibility to study mechanisms of coordination between partners of different genome types which result from a network of signal exchanges between ciliate and algae.
