The genome of a giant clam zooxanthella (Cladocopium infistulum) offers few clues to adaptation as an extracellular symbiont with high thermotolerance [PDF]

BMC Genomics
Background Cladocopium infistulum (Symbiodiniaceae) is a dinoflagellate specialized to live in symbiosis with western Pacific giant clams (Tridacnidae). Unlike coral-associated symbionts, which reside within the host cells, C.

Membrane vectorial lipidomic features of coral host cells’ plasma membrane and lipid profiles of their endosymbionts Cladocopium [PDF]

Communications Biology
The symbiotic relationships between coral animal host and autotrophic dinoflagellates are based on the mutual exchange and tight control of nutritional inputs supporting successful growth.

Fine‐Scale Geographic Variation of Cladocopium in Acropora hyacinthus Across the Palauan Archipelago [PDF]

Ecology and Evolution
Symbiont genotype plays a vital role in the ability of a coral host to tolerate rising ocean temperatures, with some members of the family Symbiodiniaceae possessing more thermal tolerance than others.

Insights on the biochemical and cellular changes induced by heat stress in the Cladocopium isolated from coral Mussismilia braziliensis

Frontiers in Microbiology, 2022
Corals are treatened by global warming. Bleaching is one immediate effect of global warming, resulting from the loss of photosynthetic endosymbiont dinoflagellates.

Persistent Legacy Effects of Marine Heatwaves on Coral Symbioses. [PDF]

Glob Chang Biol
The algal symbionts hosted by Platygyra ryukyuensis corals on Kiritimati Island were distributed according to their exposure to local human disturbance before an extreme marine heatwave (1). The symbionts hosted by corals underwent a major shift as a result of this acute heatwave disturbance, with transient symbionts detected in corals at less turbid ...

Resolving widespread and endemic dinoflagellates (Symbiodiniaceae) mutualistic with Indo-Pacific octocorals reveals differences in specificity based on host phylogeny. [PDF]

J Phycol
Abstract Endosymbionts in the dinoflagellate family Symbiodiniaceae can form mutualisms with a diverse array of host invertebrates, constituting a widespread and ecologically important family. While those associated with reef‐building corals (order Scleractinia) have received considerable research attention, the diversity and ecology of zooxanthellae ...

Cell wall proteomic analysis of the cnidarian photosymbionts Breviolum minutum and Cladocopium goreaui [PDF]

Journal of Eukaryotic Microbiology, 2022
The algal cell wall is an important cellular component that functions in defense, nutrient utilization, signaling, adhesion, and cell-cell recognition-processes important in the cnidarian-dinoflagellate symbiosis.

Stress-Resistant Symbiodiniaceae and Diverse Bacterial Communities Promote Coral Persistence in Variable, Multi-Stressor Environments. [PDF]

Ecol Evol
Corals living in multi‐stressor bays in Curaçao maintain stress‐tolerant symbiotic algae and specialized bacterial communities in comparison to those in nearby reefs. These findings provide insight into how Caribbean coral holobionts persist in extreme and marginal conditions and may respond under future environmental conditions.

Rapid Evolution in a Coral Population Following a Mass Mortality Event. [PDF]

Evol Appl
ABSTRACT Globally, corals face an increased frequency of mass mortality events (MMEs) as populations experience repeated marine heatwaves which disrupt their obligate algal symbiosis. Despite greater occurrences of MMEs, the relative roles of the environment, host, and symbiont genetic variation in survival, subsequent recovery, and carry‐over effects ...

Algal Symbionts Indicate Heatwave Vulnerability in Corals From Hotspots but Not From Thermal Refugia. [PDF]

Mol Ecol
ABSTRACT Reef‐building corals face continued declines due to climate change‐amplified marine heatwaves. In addition to affecting coral heat tolerance, corals' algal endosymbionts (family Symbiodiniaceae) can reflect their prior heatwave exposure, although understanding is often limited to heatwave‐induced shifts between symbiont genera.
