Pan-Caribbean emergence and persistence of Durusdinium spp. driven by bleaching stress

Marine Ecology - Progress Series
The increasing severity and frequency of mass bleaching events has placed shallow-water tropical coral reefs at risk of significant decline in the coming decades. The association of endosymbiotic dinoflagellates (Family: Symbiodiniaceae) with corals is regulated by local environmental conditions along with evolutionary history and ...

Dispersal, genetic variation, and symbiont interaction network of heat-tolerant endosymbiont Durusdinium trenchii: Insights into the adaptive potential of coral to climate change

Science of The Total Environment, 2020
Global warming has degraded coral reef ecosystems worldwide. Some corals develop thermal tolerance by associating with heat-tolerant Symbiodiniaceae. Here, we studied the mechanisms surrounding the dispersal, genetic variation and symbionts interaction of heat-tolerant Durusdinium trenchii across 13° latitudes in the South China Sea (SCS), to explore ...

Sub‐cellular imaging shows reduced photosynthetic carbon and increased nitrogen assimilation by the non‐native endosymbiont Durusdinium trenchii in the model cnidarian Aiptasia

Environmental Microbiology, 2020
Hosting different symbiont species can affect inter-partner nutritional fluxes within the cnidarian-dinoflagellate symbiosis. Using nanoscale secondary ion mass spectrometry (NanoSIMS), we measured the spatial incorporation of photosynthetically fixed 13 C and heterotrophically derived 15 N into host and symbiont cells of the model symbiotic cnidarian ...

Higher population genetic diversity within the algal symbiontDurusdiniuminPocillopora verrucosafrom Mexican Pacific reefs correlates with higher resistance to bleaching after the El Niño 2015–16 event

Marine Ecology, 2021
AbstractZooxanthellae are dinoflagellate algae belonging to the family Symbiodiniaceae that provide energy and oxygenation to corals, allowing them to develop a high calcification rate. Additionally, some species of these algal symbionts seem to be related to coral resistance to particular environmental conditions, and such responses have a high ...

Nitrogen concentration influences growth performance and biochemical composition of the endosymbiotic dinoflagellate Durusdinium Glynnii

Archives of Microbiology
Endosymbiotic dinoflagellates are promising sources of biomolecules with high biotechnological potential. However, knowledge on their cultivation strategies and physiological responses to nutrient modulation remains limited. This study evaluated the effects of different nitrogen concentrations-resulting in nitrogen-to-phosphorus (N: P) ratios of 0:1, 7:

Potential Trade‐Off Between Temperature and Tissue Loss Resistance in Corals Associating With Algal Symbionts in the Genus Durusdinium

Global Change Biology
ABSTRACT The symbioses between corals and microorganisms, including the endosymbiotic dinoflagellates (family Symbiodiniaceae) and bacteria, are central to coral health and functioning. Certain species of Symbiodiniaceae in the genus Durusdinium are known to confer enhanced ...

Coral‐associated Symbiodiniaceae exhibit host specificity but lack phylosymbiosis, with Cladocopium and Durusdinium showing different cophylogenetic patterns

New Phytologist
Summary Altering the composition of the Symbiodiniaceae community to adapt to anomalous sea water warming represents a potential survival mechanism for scleractinian corals. However, the processes of Symbiodiniaceae assembly and long‐standing evolution of coral–Symbiodiniaceae interactions remain unclear.
