The complete mitochondrial genome of the Honduran white bat Ectophylla alba (Allen 1982) (Chiroptera: Phyllostomidae).
The Honduran white bat, Ectophylla alba (Allen 1982), is one of eight species belonging to the family Phyllostomidae that exclusively roosts in tents. Due to its restricted distribution, habitat specificity, and diet requirements, E. alba has been strongly affected by habitat loss and fragmentation during the last decade. In this study, we developed the first genomic resource for this species; we assembled and analyzed in detail the complete mitochondrial genome of E. alba. The mitogenome of E. alba is 16,664 bp in length and is comprised of 13 protein coding genes (PCGs), 2 ribosomal RNA genes, 22 transfer RNA genes (tRNAs), and a putative Control Region (CR) 1,232 bp in length. Gene arrangement in the mitochondrial chromosome of E. alba is identical to that reported before in other species of co-familiar bats. All PCGs are under purifying selection, with atp8 experiencing the least selective pressure. In all PCGs, codons ending with adenine are preferred over others ending in thymine and cytosine. Except tRNA-Serine 1, all tRNAs exhibit a cloverleaf secondary structure. The CR of E. alba exhibits three domains commonly described in other mammals, including bats; extended terminal associated sequences (ETAS), central, and conserved sequence block (CSB). A ML phylogenetic reconstruction of the family Phyllostomidae based on all 13 mitochondrial PCGs confirms the monophyletic status of the subfamily Sternodermatinae and indicates the close relationship between E. alba and the genus Artibeus. This is the first genomic resource developed for E. alba and represents the first step to improving our understanding of the genomic underpinnings involved in the evolution of specialization as well as acclimatization and adaptation to local and global change of specialist bats.
