Comparative mitogenomics of the Decapoda reveals evolutionary heterogeneity in architecture and composition

Abstract The emergence of cost-effective and rapid sequencing approaches has resulted in an exponential rise in the number of mitogenomes on public databases in recent years, providing greater opportunity for undertaking large-scale comparative genomic and systematic research. Nonetheless, current d...
