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

## TL;DR

This paper presents the genome and microbial metagenome of the sponge Corticium candelabrum, including detailed gene annotations and bacterial genomes.

## Contribution

The study provides a high-quality chromosomal genome assembly and metagenome of a sponge species, including 44 high-quality bacterial MAGs.

## Key findings

- The sponge genome is 185.49 megabases long with 26,198 protein-coding genes.
- The mitochondrial genome is 18.19 kilobases and 99.4% of the assembly is scaffolded into 22 chromosomal pseudomolecules.
- 53 bacterial genomes were identified, including 44 high-quality MAGs from diverse phyla.

## Abstract

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)
