Two complete mitogenomes of Ocypodoidea(Decapoda: Brachyura), Cleistostoma dilatatum(Camptandriidae) and Euplax sp.(Macrophthalmidae) and its phylogenetic implications

引用

Acta Oceanologica Sinica 2023年第4期42卷 81-92页

作者： Ying Zhang Liming Wei bingjian liu Liqin liu Zhenming Lü Li Gong National Engineering Laboratory of Marine Germplasm Resources Exploration and Utilization National Engineering Research Center for Facilitated Marine AquacultureZhoushan 316022China Marine Science and Technology College Zhejiang Ocean UniversityZhoushan 316022China

Complete mitochondrial genomes(mitogenomes) can provide useful information for phylogenetic relationships,gene rearrangement, and molecular evolution. In the present study, two newly sequenced mitogenomes of Ocypodoidea(Cleistostoma dilatatum and Euplax sp.) were reported for the first time, which are 15 444 bp and16 129 bp in length, respectively. Cleistostoma dilatatum is the first species in the family Camptandriidae whose complete mitogenome was sequenced. Each mitogenome contains an entire set of 37 genes and a putative control region, but their gene arrangements are largely different. Tandem duplication and random loss model is proposed to account for their gene arrangements. Comparative genomic analyses of 19 mitogenomes clustering in one branch reveal that 18 of them shared the same gene rearrangement, while that of C. dilatatum mitogenome was consistent with the ancestral gene arrangement of Brachyura. The dN/dS ratio analysis shows that all PCGs are evolving under purifying selection. Phylogenetic analyses show that all Macrophalmidae species cluster together as a group, and then form a sister clade with Camptandriidae. Moreover, the polyphyly of three superfamilies(Ocypodoidea, Eriphioidea, and Grapsoidea) is reconfirmed. These findings help to confirm the phylogenetic position of Camptandriidae, as well as provide new insights into the phylogeny of Brachyura.

堆垛机是起重运输行业的重要设备,其在计算机系统的控制下,通过轨道在立体仓库里高效、绿色地往返穿梭,精确停在指位置并存取货物。堆垛机以最短时间从静止状态提升至高速运动状态,在保持一段时间后逐渐减速直至停止,由于受到本身结构的影响,堆垛机以何种速度运行成为目前需要解决的问题。文中提出用速度曲线表示堆垛机的运动特性,并对其进行优化研究。传统的速度曲线优化对目标函数有较强的依赖性和严格性,基于权重分析法(AHP)得到堆垛机关键性能指标的权重,提出改进遗传算法(GA)对速度曲线进行优化。仿真结果表明:该算法具有优化精度高、鲁棒性好的优点,在该领域具有良好的参考意义和实用价值。
