The chromosomal genome sequence of the sponge Phakellia ventilabrum (Linnaeus, 1767) and its associated microbial metagenome sequences

TL;DR

This paper presents the genome sequence of the sponge Phakellia ventilabrum and its associated microbial genomes, providing insights into both the sponge and its symbiotic microbes.

Contribution

The study provides a high-quality chromosomal genome assembly and metagenome sequences of Phakellia ventilabrum and its associated microbes.

Findings

The sponge genome is assembled into 25 chromosomal pseudomolecules with 21,622 protein-coding genes.

Thirty-three binned genomes were generated, including eight high-quality MAGs from diverse taxa.

The mitochondrial genome is 24.36 kilobases in length.

Abstract

We present a genome assembly from a specimen of
Phakellia ventilabrum (Porifera; Demospongiae; Bubarida; Bubaridae). The genome sequence has a total length of 211.92 megabases. Most of the assembly (99.97%) is scaffolded into 25 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 24.36 kilobases in length. Gene annotation of this assembly by Ensembl identified 21 622 protein-coding genes. Thirty-three binned genomes were generated from the metagenome assembly, of which eight were classified as high-quality metagenome assembled genomes (MAGs) and of which four of the MAGs are fully circular. The MAGs were taxonomically assigned to Pseudomonadota (i.e. Candidatus Poriferihabitaceae), Nitrospirota, Nitrospinota, and the archaeal Nitrosopumilus clade.
