Coral bleaching looks like a reef-scale catastrophe. But it starts as a breakdown between single cells.
Led by @AMBonacolta, we watched it at that scale for the first time: the first single-cell transcriptomics of a bleaching coral 🪸 #CoralReefs

ALT 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.

📄 Take-home: do not throw away your chloroplast reads. Plastid-derived 16S sequences carry real ecological signal, and microeukaryote-inclusive surveys are needed to understand the coral holobiont. #corals #microbiome

🌱 Ostreobium: six distinct clades recovered, three described here for the first time. The North West Pacific emerges as a potential hotspot of Ostreobium diversity.

🧬 New #protist diversity hiding in the discard pile. Phylogenetic placement of apicomplexan reads classified most as Corallicolida and revealed ASVs consistent with a novel apicomplexan-related lineage, tentatively named ARL-XXI.
Javier del Campo retweeted
🧩 Host specificity is strong. The most abundant ASVs are mostly restricted to particular coral lineages, a pattern consistent with phylosymbiosis and supported by ASV-level community profiles across the whole dataset.
Javier del Campo retweeted
🔬 Two groups dominate everywhere, across lineages, health states, and oceans: Corallicolida (coral apicomplexans) and Ostreobium (skeleton-boring green algae). After Symbiodiniaceae, these are the most widespread plastid-bearing coral symbionts. #symbiosis

🌍 Scale: 2,679 samples from 45 studies, reprocessed into 10,950 ASVs from 13 million read pairs. 73 coral species, 23 families, all major ocean regions, and three host health states.

🗑️ The idea: in coral 16S rRNA #microbiome datasets, reads assigned to “chloroplast” are usually discarded as noise. But those reads come from real organisms, the plastid-bearing eukaryotes in the holobiont. Joana went back and kept them.
Javier del Campo retweeted
🪸 New preprint from the lab, and a first lead-author paper for @Joanakrause99: a global meta-analysis of plastid-bearing microeukaryotes living in #corals, built from sequences most 16S studies throw away. With @BradWeilerDives and @fonamental, at @IBE_Barcelona.

El matrimoni antivacunes que va treure #Vèrtex3Cat ahir al vespre ja els van portar a @maticatradio al març.
Es tracta d'una opinió tan poc estesa, que han hagut de repetir dos cops als mitjans públics...

Responsables de @som3cat, esteu posant al mateix nivell una posició marginal gens documentada i unes polítiques públiques de salut recolçades en milers de dades científiques; fent d'altaveus de la desiformació i donant legitimitat a la maguferia.
