# The genome sequence of the white-lipped garden snail, Cepaea hortensis (Müller, 1774) (Stylommatophora: Helicidae)

## TL;DR

This paper presents the genome sequence of the white-lipped garden snail, including a detailed assembly and gene annotation as part of a larger project to map British and Irish eukaryotic species.

## Contribution

The paper provides a high-quality reference genome for Cepaea hortensis, including chromosomal scaffolding and mitochondrial genome assembly.

## Key findings

- The genome assembly is 3,168.99 megabases long, with 97.52% scaffolded into 22 chromosomal pseudomolecules.
- The mitochondrial genome is 15.08 kilobases in length and has been fully assembled.
- Gene annotation identified 17,974 protein-coding genes using Ensembl.

## Abstract

We present a genome assembly from an individual
Cepaea hortensis (white-lipped garden snail; Mollusca; Gastropoda; Stylommatophora; Helicidae). The genome sequence has a total length of 3 168.99 megabases. Most of the assembly (97.52%) is scaffolded into 22 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 15.08 kilobases. Gene annotation of this assembly on Ensembl identified 17 974 protein-coding genes. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
