For the first time, we watched bacteria and microbial eukaryotes shift together during bleaching: suspected nitrifiers dropped early, while suspected denitrifiers and nitrate reducers rose, along with blooms of chlorophytes, diatoms, and labyrinthulids. #Microbiome #Protists #MicrobialEcology

Mucocytes (mucus-producing gland cells) expanded under heat stress and appear to play an active role in the bleaching response.

The two symbionts responded differently, especially in nitrogen-cycling transcripts. The host's gastrodermal cells showed apparent suppression of heat-stress genes, depending on which symbiont they carried. Bleaching is not one process; it is many, cell by cell. #CoralBleaching

We heat-stressed Orbicella faveolata, which hosts two co-dominant symbionts, Durusdinium and Breviolum, and combined scRNA-seq with 16S + 18S + ITS2 metabarcoding and photochemistry. #scRNAseq

Four-panel figure of the coral holobiont through heat stress. Panel A: photosynthetic efficiency over time, stable in blue control corals, declining in red heat-treated corals. Panel B: photos of coral cores paling from healthy to bleached, each paired with a UMAP plot of holobiont cell types in Orbicella faveolata. Panel C: bar chart of cell-type abundance shifts during bleaching. Panel D: heatmap of gene expression changes across cell types at each stage.

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)

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.
