The complete mitogenome the longtail butterfly ray (Gymnura poecilura) was first presented in this study. It is 17,874 bp in length, contains 37 genes with the typical gene order and transcriptional direction in vertebrates. The overall base composition is: 28.5% A, 26.5% T, 15.0% G and 30.1% C. There are 26 bp overlaps and 41 bp short intergenic spaces located in 7 and 16 gene junctions, respectively. Two start codons (ATG and GTG) and two stop codons (TAG and TAA/T) were used in protein-coding genes. The origin of L-strand replication (OL) was found between tRNA-Asn and tRNA-Cys genes. The control region has the same A and C contents (28.8%).
本研究首次公布了长尾蝴蝶魟（Gymnura poecilura）的完整线粒体基因组。其长度为17,874 bp，包含37个基因，具有脊椎动物典型的基因排列顺序和转录方向。总体碱基组成为：A占28.5%，T占26.5%，G占15.0%，C占30.1%。分别在7个和16个基因连接处存在26 bp的重叠和41 bp的短基因间隔。蛋白质编码基因使用了两个起始密码子（ATG和GTG）和两个终止密码子（TAG和TAA/T）。轻链复制起点（OL）位于tRNA-Asn和tRNA-Cys基因之间。控制区的A和C含量相同（28.8%）。
