摘要

Toxic marine dinoflagellate species of the genus Dinophysis Ehrenberg are obligate mixotrophs that require feeding on the ciliate Mesodinium rubrum and light to achieve growth. It is now well known that they harbour plastids of cryptophyte origin, particularly of the genus Teleaulax, Plagioselmis or Geminigera group (TPG clade). Nevertheless, whether these plastids are permanent, or periodically acquired from M. rubrum prey, need additional studies in different phototrophic Dinophysis species. The origin of plastids from Dinophysis acuta Ehrenberg, one of the main agents of diarrhetic shellfish poisoning (DSP) outbreaks in Western Europe, was investigated here. Cross feeding-starvation experiments were carried out with cultures of D. acuta using M. rubrum as prey, the latter fed with two cryptophyte species, Teieaulax amphioxeia Hill and Teleaulax gracilis, belonging to the TPG clade in addition to Falcomonas sp. and Hemiselmis sp. The fate of cryptophyte plastids transferred to D. acuta through its ciliate prey was investigated using the plastid psbA gene as a tracer.
