The genome sequence has a total length of 339.18 megabases. Most of the assembly (98.66%) is scaffolded into 16 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 18.73 kilobases. ## Linked entities - **Species:** Gorgonia ventalina (taxon 204384) ## Full-text entities - **Genes:** SNAI1 (snail family transcriptional repressor 1) [NCBI Gene 6615] {aka SLUGH2, SNA, SNAH, SNAIL, SNAIL1, dJ710H13.1}, NCOR2 (nuclear receptor corepressor 2) [NCBI Gene 9612] {aka CTG26, N-CoR2, SMAP270, SMRT, SMRTE, SMRTE-tau} - **Diseases:** aspergillosis (MESH:D001228), stony coral tissue loss disease (MESH:D003240), fungal (MESH:D009181) - **Chemicals:** Poly(A) (MESH:D011061), TC (MESH:D013667), Nucleotide (MESH:D009711), PB (MESH:D007854), formaldehyde (MESH:D005557), Arima (MESH:D020912), AMPure (-) - **Species:** Ophiothela mirabilis (species) [taxon 2485341], Cyphoma signatum (species) [taxon 1890726], Scleractinia (stony corals, order) [taxon 6125], PX clade (clade) [taxon 569578], Mycoplasmatales bacterium (species) [taxon 2023991], Tritonicula hamnerorum (species) [taxon 508446], Hermodice carunculata (marine fireworm, species) [taxon 259844], Simnialena uniplicata (species) [taxon 848635], Cyphoma gibbosum (species) [taxon 217775], Symbiodinium (genus) [taxon 2949], Aspergillus sydowii (species) [taxon 75750], Octocorallia (sea whips, subclass) [taxon 6132], Dendrogyra cylindrus (species) [taxon 214965], Cymbovula acicularis (species) [taxon 848633], Anthozoa (anthozoans, class) [taxon 6101], Gorgonia ventalina (species) [taxon 204384] ## Figures 6 figures with captions in the complete paper: https://tomesphere.com/paper/PMC12856254/full.md --- Source: https://tomesphere.com/paper/PMC12856254
