The complete mitochondrial genome of the critically endangered Lesser Antillean iguana (Iguana delicatissima; Squamata: Iguanidae)
The Lesser Antillean iguana, Iguana delicatissima Laurenti 1768, is one of the most endangered vertebrate taxa in the West Indies. This species faces significant threats, including introgressive hybridization with the introduced congener Iguana iguana. We deploy a combination of off-target sequence...

| Sumario: | The Lesser Antillean iguana, Iguana delicatissima Laurenti 1768, is one of the most endangered vertebrate taxa in the West Indies. This species faces significant threats, including introgressive hybridization with the introduced congener Iguana iguana. We deploy a combination of off-target sequence capture obtained from Illumina reads and targeted Sanger reads to assemble the mitochondrial genome of I. delicatissima. The mitogenome is 16,616 bp in length and is comprised of 13 protein-coding genes, two ribosomal subunits (rRNAs), 22 transfer RNAs, and a control region. Gene order is identical to that of congener I. iguana and other closely related taxa, absent of any tandem repeat regions. We show the phylogenetic utility of the mitogenome with a maximum-likelihood analysis, which yields a topology concordant with previous studies of iguanine taxa. We are hopeful that this genomic resource will be useful in further informing applied conservation and management for this critically endangered species. |
