Abstract In previous studies, we have established approximately 15 cultured cell‐lines derived from planula larvae of Acropora tenuis . Based on their morphology and behavior, these cells were classified into three types, flattened amorphous (FAmCs), vacuolated adherent (VAdCs), small smooth (SSmCs). FAmCs include fibroblast‐like spherical, brilliant brown (BBrCs), which are transformable to each other. To examine the larval origin cell raised antibodies: anti‐AtMLRP2 that appears recognize FAmC, anti‐AtAHNAK for BBrC, anti‐AtSOMP5 anti‐AtEndoG SSmC, anti‐AtGal anti‐AtFat4 VAdC, respectively. Anti‐AtMLRP2 antibody stained in vivo stomodeum neuroblast‐like embedded ectoderm around aboral pole. Anti‐AtAHNAK neuron‐like cells, both also with neuron‐specific tubulin β‐3 antibody. These results suggest vitro BBrCs share neuronal properties common. Two antibodies SSmCs, anti‐AtEndoG, suggesting SSmCs properties. VAdCs, anti‐AtFat4, endoderm VAdCs Therefore, lines appear retain stomodeum, neuroblast, ectoderm, or endoderm. Each them may be used future investigations reveal cellular molecular types coral larvae, such as potential symbiosis.

Scleractinian corals are essential ecosystem engineers, forming the basis of coral reef ecosystems. However, these organisms in decline globally, part due to rising disease prevalence. Most dependent on symbiotic interactions with single-celled algae from family Symbiodiniaceae meet their nutritional needs, however, suppression host immunity may be this relationship. To explore immunological consequences algal symbioses scleractinian corals, we investigated constitutive immune activity facultatively coral, Astrangia poculata . We compared metrics (melanin synthesis, antioxidant production and antibacterial activity) between colonies varying symbiont density. Symbiont density was positively correlated both melanin concentration, likely as a result dual roles pathways symbiosis regulation. Our results confirm complex nature relationships highlight need for nuanced approaches when considering relationships.

Abstract Oxylipin signaling has been suggested as a potential mechanism for the inter-partner recognition and homeostasis regulation of cnidarian-dinoflagellate symbiosis, which maintains ecological viability coral reefs. Here we assessed effects symbiosis symbiont identity on model cnidarian, sea anemone Exaiptasia diaphana, using mass spectrometry to quantify octadecanoid oxylipins (i.e., 18-carbon-derived oxygenated fatty acids). A total 84 octadecanoids were reported, distinct stereospecificity was observed synthesis R- S-enantiomers symbiont-free anemones free-living cultured dinoflagellate symbionts, respectively. Symbiont-derived 13(S)-hydroxy-octadecatetraenoic acid (13(S)-HOTE) linked 13(S)-lipoxygenase translocated host with 32-fold increase, suggesting it biomarker agonist receptors that regulate inflammatory transcription. Only native Breviolum minutum decreased abundance pro-inflammatory 9(R)-hydroxy-octadecadienoic (9(R)-HODE) in host. In contrast, non-native Durusdinium trenchii marked by higher autoxidation-derived octadecanoids, corroborating previous evidence cellular stress this association. The putative pathways reported here suggest foundational knowledge gaps can support bioengineering selective breeding more optimal host-symbiont pairings enhance resilience survival
