The complete mitochondrial genome of the pink shrimp Farfantepenaeus duorarum (Burkenroad, 1939) (Decapoda: Dendrobranchiata: Penaeidae)

Farfantepenaeus duorarum () is a commercially harvested decapod shrimp that ranges from the eastern coast of the United States, through the Gulf of Mexico, and as far south as Isla Mujeres, Mexico. We report for the first time the complete mitochondrial genome of F. duorarum. The mitochondrial genome is 15,971 base pairs in length and is comprised of 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, and 22 transfer RNA genes. An intergenic space 982 bp in length located between the rrnS (12S) and trnI (Isoleucine) genes is presumed to be the D-loop. The mitochondrial gene order in F. duorarum is identical to that reported for congeners. To assess selection pressures within the mitochondrial genome, K-A/K-S ratios were calculated for all PCGs, and show values < 1, indicating that all genes are evolving under purifying selection. This work contributes one more mitochondrial genome to the penaeid shrimps, an economically targeted group.

Automated summary

This study reports the complete mitochondrial genome of Farfantepenaeus duorarum and reveals its conserved gene order with congeners. The analysis of K-A/K-S ratios suggests that purifying selection is acting on all coding genes in F. duorarum's mitochondrial genome. This research provides valuable insights into the genomic features and evolutionary adaptations of F. duorarum.
