Abstract Among all organisms, the dinoflagellates display the highest diversity in their plastids, indicating multiple plastid origins from a broad variety of algae by replacing the common peridinin-containing plastid. One such replacement seems to have taken place in the genus Dinophysis, where the plastids show characteristics of a cryptomonad. Natural populations of D. acuminata. D. acuta and D. norvegica were collected from the Baltic Sea, North Sea and northern Atlantic Ocean. We sequenced…

D. caudata may already have its own CR‐MAL01–type permanent plastid, with two types of plastids obtained from M. rubra being lost within 1 month, highlighting the need to identify more accurately the origin of plASTids in newly isolated photosynthetic Dinophysis species to resolve the issue ofplastid permanence.

The present findings suggest that these Dinophysis species engulfed and temporarily retained plastids from a cryptophyte, and may have originally possessed peridinin-type plastid and lost it subsequently, and adopted a new plASTid from a Cryptophyte.

The results for all three genes fit the idea that dinoflagellate chloroplasts originated from red algae by a secondary endosymbiosis, possibly the same one as for chromists and Sporozoa.

The form II type RUBISCO found in the dinophytes is unique for eukaryotes, otherwise known only in some anaerobic bacteria, and it is disputed whether the original dinophyte chloroplasts are derived from a prokaryotic or an eUKaryotic endosymbiosis.

It is postulated that the plastid of peridinin- and fucoxanthin-containing dinoflagellates originated from a haptophyte tertiary endosymbiosis that occurred before the split of these lineages.
