Farfantepenaeus duorarumis是一种商业捕捞的十足虾，分布在美国东海岸，穿过墨西哥湾，向南远至墨西哥的Isla Mujeres。我们首次报道了完整的线粒体基因组ofF。duorarum。线粒体基因组全长15971个碱基对，由13个蛋白质编码基因（PCGs）、2个核糖体RNA基因和22个转移RNA基因组成。位于rrnS （12S）和trnI（异亮氨酸）基因之间的982 bp的基因间空间被认为是d环。线粒体基因序列与同源基因相同。为了评估线粒体基因组内的选择压力，计算了所有PCGs的KA/ ksratio，结果显示值< 1，表明所有基因都在纯化选择下进化。这项工作为对虾提供了一个线粒体基因组，对虾是一个经济目标群体。
Farfantepenaeus duorarumis 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 ofF. 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 inF. duorarumis identical to that reported for congeners. To assess selection pressures within the mitochondrial genome, KA/KSratios 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.
