It is well documented that organelles can be retained and used by predatory organisms, but in most cases such sequestrations are limited to plastids of algal prey. Furthermore, sequestrations of prey organelles are typically highly ephemeral as a result

Photosynthesis in the ciliate Mesodinium rubrum is achieved using a consortium of cryptophyte algal organelles enclosed in its specialized vacuole. A time-series microarray analysis was conducted on the photosynthetic ciliate using an oligochip containing

Mesodinium rubrum Lohmann is a mixotrophic ciliate and one of the best studied species exhibiting acquired phototrophy. To investigate the fate of cryptophyte organelles in the ciliate subjected to starvation, we conducted ultrastructural studies of a

Karlodinium veneficum is a common member of the phytoplankton in coastal ecosystems, usually present at relatively low cell abundance (102 to 103 mL−1), but capable of forming blooms of 104 to 105 cells mL−1 under appropriate conditions. We present evidence

Stealing prey plastids for metabolic gain is a common phenomenon among protists within aquatic ecosystems.1 Ciliates of the Mesodinium rubrum species complex are unique in that they also steal a transcriptionally active but non-dividing prey nucleus,
