Here, we report the draft genome sequences of Hoeflea sp. strain E7-10 and Hoeflea prorocentri PM5-8, isolated from a bleached hard coral and a culture of marine dinoflagellate, respectively. Genome sequencing for host-associated isolates Hoeflea sp. E7-10 and H. prorocentri PM5-8 can provide basic genetic information to explore potential roles in their hosts.

The heterotrophic Crypthecodinium cohnii is a major model for dinoflagellate cell biology, and a major industrial producer of docosahexaenoic acid, a key nutraceutical and added pharmaceutical compound. Despite these factors, the family Crypthecodiniaceae is not fully described, which is partly attributable to their degenerative thecal plates, as well as the lack of ribotype-referred morphological description in many taxons. We report here significant genetic distances and phylogenetic cladding…

The benthic dinoflagellate Prorocentrum lima is among the most common toxic morphospecies with a cosmopolitan distribution. P. lima can produce polyketide compounds, such as okadaic acid (OA), dinophysistoxin (DTX) and their analogues, which are responsible for diarrhetic shellfish poisoning (DSP). Studying the molecular mechanism of DSP toxin biosynthesis is crucial for understanding the environmental driver influencing toxin biosynthesis as well as for better monitoring of marine ecosystems….

We sequenced the genome of Roseibium sp. strain Sym1, a strain isolated from a monoculture of a Symbiodiniaceae marine dinoflagellate, Symbiodinium linucheae, a microalgal symbiont of cnidarians. The completed genome consists of one circular chromosome of 6,694,563 bp and four plasmids of 192,102 bp, 160,136 bp, 120,881 bp, and 89,413 bp.

The mutualistic cnidarian-dinoflagellate symbiosis underpins the evolutionary success of stony corals and the persistence of coral reefs. However, a molecular understanding of the signalling events that lead to the successful establishment and maintenance of this symbiosis remains unresolved. For example, the phosphatidylinositol (PI) signalling pathway has been implicated during the establishment of multiple mutualistic and parasitic interactions across the kingdoms of life, yet its role within…

Dinoflagellates are a diverse protist group possessing many unique traits. These include (but are not limited to) expansive genomes packaged into permanently condensed chromosomes, photosynthetic or cryptic plastids acquired vertically or horizontally in serial endosymbioses, and a ruffle-like transverse flagellum attached along its length to the cell. When reconstructing character evolution, early branching lineages with unusual features that distinguish them from the rest of the group have…
