We hypothesize that CaCO3 precipitation in marine fish may not solely be a host-driven process, but potentially the result of a functional symbiosis with gut-associated Vibrio bacteria, expanding the role of symbiosis in marine biomineralization and global biogeochemical cycles.
We identified a high abundance of vibrios associated with ichthyocarbonates with the metabolic potential for CaCO3 precipitation. Specifically, we observe the expression of ureR by Photobacterium damselae subsp. damselae, which can induce the precipitation of CaCO3 via the production of bicarbonate!
Marine fish produce CaCO3 precipitates ("ichthyocarbonates") in their guts as part of their osmoregulation strategy. Through this, fish may generate up to 9.04 Pg of new CaCO₃ annually, rivaling coccolithophores and pelagic foraminifera in global carbonate production. (Photo: Joshua Prezant)

Despite a relatively stable microbiome, we reveal that microbial co-occurrence networks shift between daytime carbohydrate catabolism and nighttime methylotrophy, indicating metabolic hand-offs across domains of life within the holobiont. #SymbioSky #ProtistsOnSky
To help reduce the annotation gap of functional assignment in non-model organisms like corals, we supplemented our host gene ontology enrichment terms using protT5 protein language model to predict functions for poorly annotated proteins, adding more context beyond standard homology-based pipelines.
We uncover transcriptional rhythms in the coral, including dawn initiated RNA biosynthesis, midday & dusk regulation of phosphate metabolism, and midnight activation of stress and repair pathways. Breviolum sp. displays tightly regulated cell cycle dynamics and nutrient transport oscillations.
🚨New Pub Alert🚨 We present a system-level molecular framework of natural diel regulation in the stony coral P. strigosa, integrating host & symbiodiniaceae transcriptomics with microbiome dynamics over 6hr intervals. Amazing to publish this PhD work @miamirosenstiel.bsky.social 👉 shorturl.at/TzYEr

Your students arrive in Curaçao earlier than you and say: We are bored. Can we do that extra diel cycle sampling that we talked about 🤔 ? Your only answer as a PI: Sure 😬 The outcome? Sleep-deprived students and an excellent work on the #coral holobiont rhythmicity 🪸🦠⏰ #symbiosis #microbiome
Brad Weiler@bradweilerdives.bsky.social · last yr.🚨New Preprint Alert🚨 P. strigosa, a reef-building coral shows tightly regulated transcriptional control over natural diel cycles. #CoralReefs #Symbiosky #bioinformatics #marinemicrobes #protistsonsky www.biorxiv.org/content/10.1...
This effort was a 'tour de force' only made possible by my incredible lab @ambonacolta.bsky.social and @fonamental.bsky.social. Absolutely thrilled to get this part of my Ph.D. dissertation out, thank you everyone involved!
Lastly, we explored microbiome structure 🦠 through time. Broadly, the microbial composition is largely stable through time, with notable taxon-specific changes through day/night light cycles. During the day carbohydrate catabolizers show enrichment, while night hours feature methylotrophs.
Similar to the host, the symbiont Breviolum showed diel regulated transcription, although more subtle. Time-specific functions were recovered, showing metabolite transfer and nitrogen/carbohydrate metabolism through daytime, while cellular division and reorganization/turnover during the dark hours.
In the coral host, we observed dawn as a molecular surge in RNA metabolism 🧬, midday exhibits high phosphate regulation 🔋, dusk reflects lipid & amino acid metabolism ♻️, and midnight shows mRNA catabolism & mitochondrial reorganization 🗂️. Most striking, we recovered ~30% transcripts as rhythmic.
