| 内容記述 | The mutualistic symbiosis between giant sea anemones, Symbiodiniaceae algae, and anemonefish is a classic example of mutualism in coral reef ecosystems. Despite its significance, the mechanisms involved remain incompletely understood. This is due to our limited knowledge regarding giant sea anemone taxonomy, the different contributions to symbiosis, and the roles of the three widely dissimilar partners. To address these gaps, I conducted a transcriptome study of giant anemones in Okinawa, revealing molecular similarities, phylogenetic relationships, and anemonefish host preferences. The study identified three distinct groups within giant sea anemones (Entacmaea, Heteractis, and Stichodactyla) with symbiotic dinoflagellates. Additionally, E. quadricolor was found to have four cryptic lineages among which two, quite divergent, live in sympatry and are associated with different anemonefish species, suggesting they may correspond to cryptic species. Investigating global gene expression changes due to the photosymbiotic relationship in S. gigantea in the presence/absence of anemonefish revealed elevated expression of nitrogen assimilation related genes, suggesting the delivery of CO2 and ammonia waste from anemonefish to anemone’s symbiosome membrane. Draft genomes of three giant sea anemones were successfully obtained, contributing to the understanding of genomic novelties in symbiotic adaptation. Taken together, these data provide solid foundations for the genomic analysis of giant sea anemones, the iconic hosts of anemonefish. | |||||||
