Transcriptomics of the <i>Anthopleura</i> Sea Anemone Reveals Unique Adaptive Strategies to Shallow-Water Hydrothermal Vent.

ABSTRACT: The nonsymbiotic sea anemone Anthopleura nigrescens dominates the shallow-water hydrothermal vents off the coast of Kueishan Island, Taiwan. These vents represent some of the world's most extreme environments, with recorded pH values as low as 1.52 and temperatures reaching 121°C. To investigate the adaptations of A. nigrescens to these extreme conditions, transcriptomic analyses were conducted to compare populations inhabiting vent and non-vent areas. To identify shared genetic mechanisms in vent-dwelling anemones, specific orthologs conserved in vent sea anemones were identified by comparing the genomic data of Anthopleura species and other sea anemones. Tank experiments with elevated temperatures were also performed to evaluate the expression profiles of genes assoc
