Impaired photoacclimation in a kleptoplastidic dinoflagellate reveals physiological limits of early stages of endosymbiosis Dinophysis dinoflagellates use plastids stolen from prey. Garric et al. show that these plastids cannot synthesize a complete phycoerythrin, a crucial photosynthetic protein. Dinophysis thus relies on prey ingestion for photoacclimation. It is noteworthy that some Dinophysis have acquired phycoerythrin synthesis genes from cryptophytes during evolution.
