The chromosomal genome sequence of the sponge, Corticium candelabrum Schmidt, 1862 and its associated microbial...

We present a genome assembly from a specimen of Corticium candelabrum (sponge; Porifera; Homoscleromorpha; Homosclerophorida; Plakinidae). The genome sequence has a total length of 185.49 megabases. Most of the assembly (99.4%) is scaffolded into 22 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 18.19 kilobases in length. Gene annotation of this assembly on Ensembl identified 26,198 protein-coding genes. The metagenome of the specimen was also assembled, and 53 binned bacterial genomes were identified, including 44 high-quality MAGs that were typical of high microbial abundance sponge and included, besides the phyla Chloroflexota (class Dehalococcoidia), Acidobacteriota (order Acidomicrobiales), Alpha- and Gammaproteobacteria, also representatives of several candidatus phyla (Candidatus Latescibacterota, Binatota, Poribacteria).
