A reproducible workflow for assembling the mitochondrial genome of Acheta domesticus (Orthoptera: Gryllidae)

In this study, we report the assembly and annotation of the mitochondrial genome (mitogenome) of Acheta domesticus from breeding facility, a species commonly known as the house cricket. This species is considered to be an important edible cricket. The mitogenome was assembled using a reproducible protocol implemented on the Galaxy Europe Server, which involved uploading paired-end fastq reads for bioinformatic analysis. The resulting mitogenome is 15,784 base pairs in length and has a GC content of 29.05%. The nucleotide composition of this mitogenome is similar to that of other insect mitogenomes, with A, T, C, and G nucleotides comprising 39.2%, 31.7%, 19.6%, and 9.5% of the mitogenome, respectively. The gene organization of the A. domesticus mitogenome is identical to that of other cricket species. The mitogenome consists of 37 genes, including 13 protein-coding genes, 22 tRNA genes, and two rRNA genes. The congruence between PCA and Bayesian evolutionary tree analysis in clustering the divergent A. domesticus sequences highlights these genomes as candidates for further study to elucidate their distinct features and evolutionary history.
