摘要: SUMMARY The fine structure of the binucleate, fucoxanthin-containing dinoflagellate Peridinium foliaceum (Stein) Biechler was re-examined for evidence an endosymbiout. The eucaryotic nucleus, chloroplasts and associated ribosome-dense cytoplasm were separated by a single invaginating membrane from rest cell. triple membrane-enclosed eyespot, mesocaryotic trichocysts accumulation bodies resided in cytoplasm. These observations suggest that P. contains membrane-bound endosymbiont, similar to already described closely related species. balticum (Levander) Lemmermann.
