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…

TLDR
The data presented here show that both a 799 bp regions of the psbA gene and 1,221 bp region of the 16S rRNA gene from Dinophysis spp.
Genetic analyses of Dinophysis spp. support kleptoplastidy.
TLDR
The results challenge the hypothesis that the plastids in Dinophysis are permanent and suggest that they are more likely to be kleptoplastids.
High-Level Congruence of Myrionecta rubra Prey and Dinophysis Species Plastid Identities as Revealed by Genetic Analyses of Isolates from Japanese Coastal Waters
ABSTRACT We analyzed cryptophyte nucleomorph 18S rRNA gene sequences retained in natural Myrionecta rubra cells and plastid 16S rRNA gene and psbA sequences retained in natural cells of several…
The marine dinoflagellate genus Dinophysis can retain plastids of multiple algal origins at the same time
The Plastid Genome of the Cryptomonad Teleaulax amphioxeia
TLDR
To clarify the phylogenetic relationships of the algae with red-algal derived plastids, phylogenetic analyses of 32 taxa were performed, including three previously sequenced cryptophyte plastid genomes containing 93 protein-coding genes.
Origin of cryptophyte plastids in Dinophysis from Galician waters: results from field and culture experiments
TLDR
The origin of Dinophysis plastids from Galician waters and their transfer in cross-feeding experiments in the laboratory are examined and 2 cryptophytes, T. minuta and P. prolonga, are confirmed, as suitable prey for M. rubrum.
psbA based molecular analysis of cross-feeding experiments suggests that Dinophysis acuta does not harbour permanent plastids

PHYLOGENETIC EVIDENCE FOR THE CRYPTOPHYTE ORIGIN OF THE PLASTID OF DINOPHYSIS (DINOPHYSIALES, DINOPHYCEAE) 1
Photosynthetic members of the genus Dinophysis Ehrenberg contain a plastid of uncertain origin. Ultrastructure and pigment analyses suggest that the two‐membrane‐bound plastid of Dinophysis spp. has…
Molecular evidence for plastid robbery (Kleptoplastidy) in Dinophysis, a dinoflagellate causing diarrhetic shellfish poisoning.
TLDR
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.
Phylogeny of Ultra-Rapidly Evolving Dinoflagellate Chloroplast Genes: A Possible Common Origin for Sporozoan and Dinoflagellate Plastids
TLDR
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 Plastid Genome of the Cryptophyte Alga, Guillardia theta: Complete Sequence and Conserved Synteny Groups Confirm Its Common Ancestry with Red Algae
TLDR
The cryptophyte plastid genome is almost completely comprised of clusters of genes that are found on the rhodophyte Porphyra purpurea, confirming its common ancestry with red algae.

Host specificity in the Richelia-diatom symbiosis revealed by hetR gene sequence analysis.
TLDR
Sequences from R. intracellularis-Hemiaulus membranaceus sampled in the Atlantic and Pacific Oceans were almost identical, demonstrating that the genetic relatedness was not dependent on geographical location and all sequences displayed a deep divergence between symbionts from different genera and a high degree of host specificity.
Dinophyte chloroplasts and phylogeny - A review
TLDR
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.
A single origin of the peridinin- and fucoxanthin-containing plastids in dinoflagellates through tertiary endosymbiosis
TLDR
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.

PRIMARY AND SECONDARY ENDOSYMBIOSIS AND THE ORIGIN OF PLASTIDS
TLDR
The theory of endosymbiosis describes the origin of plastids from cyanobacterial‐like prokaryotes living within eukaryotic host cells, and morphological, biochemical, and molecular studies provide clear evidence of a proKaryotic ancestry for plastid ancestry.
