The first complete mitochondrial genome of the intertidal barnacle Pilsbry, 1916 (Crustacea: Maxillopoda: Sessilia) is presented. The genome is a circular molecule of 15,665 bp, which encodes a set of 37 typical metazoan genes. All non-coding regions are 438 bp in length, with the longest one speculated as the control region (264 bp), which is located between and . All protein-coding genes (PCGs) have an ATD (ATA, ATT, or ATG) start codon, except , which is initiated with GTG. Remarkably, , , have incomplete stop codons (T-- or TA-) and the remaining PCGs have the complete stop codon (TAA). Phylogenetic analysis based on 13 mitochondrial PCGs shows that the members of the Archaeobalanidae and Balanidae intermingle with species from Pyrgomatidae. The results supposed that Balanidae and Archaeobalanidae are non-monophyly.
本文公布了潮间带藤壶（1916年皮尔布里分类，甲壳纲：颚足纲：无柄目）的首个完整线粒体基因组。该基因组是一个15,665 bp的环状分子，编码一组37个典型的后生动物基因。所有非编码区长度均为438 bp，最长的一个推测为控制区（264 bp），位于[具体位置1]和[具体位置2]之间。除[基因名称1]以GTG起始外，所有蛋白质编码基因（PCG）均以ATD（ATA、ATT或ATG）起始密码子开始。值得注意的是，[基因名称2]、[基因名称3]、[基因名称4]具有不完全终止密码子（T--或TA-），其余PCG具有完整的终止密码子（TAA）。基于13个线粒体PCG的系统发育分析表明，古藤壶科和藤壶科的成员与茗荷科的物种相互混杂。结果表明藤壶科和古藤壶科并非单系类群。
