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.
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.
DINOFLAGELLATES: A REMARKABLE EVOLUTIONARY
TLDR
This chapter reviews the current knowledge of gene regulation and transcription in dinoflagellates with regard to the unique aspects of the nuclear genome and the implications for understanding organellar genome evolution are discussed.

DOES DINOPHYSIS CAUDATA (DINOPHYCEAE) HAVE PERMANENT PLASTIDS? 1
TLDR
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.

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.
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.

Abstract Phaeosomes, extracellular cyanobacterial symbionts of the genus Synechococcus Nageli, of some species of tropical marine dinoflagellates were investigated for the presence of nitrogenase,
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.
