Abstract

We present the first mitochondrial genomes from Chagos Archipelago, Indian Ocean, of three putative species of reef forming Acropora (Acropora aff. tenuis, Acropora aff.cytherea and Acropora aff. orbicularis). The circular genome consists respectively of 18,334 bp, 18,353 bp and 18,584 bp. All mitochondrial genomes recovered comprise 13 protein-coding genes, two transfer RNA genes and two ribosomal RNA genes, with an overall GC content ranging from 37.9% to 38.0%. These new genomic data contribute to our increased understanding of genus Acropora and its species boundaries, ultimately aiding species monitoring and conservation efforts.

Keywords: Acropora; Chagos Archipelago; mitochondrial genome.
