Abstract

Abstract The complete mitogenome of four Scleromystax barbatus populations distributed along the species natural range was reconstructed, comprising the first study with this genus and the second with Corydoradinae specimens sampled from their natural environment and deposited in permanent collections. The mitogenome of S. barbatus is a circular molecule of 16,694 base pairs (bp) comprising 37 genes, 22 of which are tRNA, two are rRNA, 13 are protein-coding genes and one control region (D-loop). An 18-nucleotide insertion sequence was found between the ATPase subunit 6 and COIII genes. Most genes are encoded on the heavy strand, while the ND6 and eight tRNAs are found on the light strand. Phylogenetic analyses using other available Callichthyidae mitogenomes confirmed the monophyly of Callichthyinae and Corydoradinae and indicate that S. barbatus populations form a separate and more closely related branch of Corydoras nattereri + Corydoras paleatus.

barbatus硬壳菌群线粒体全基因组的研究

摘要对分布在自然分布范围内的4个barbatus硬霉属(sclomystax barbatus)种群进行了完整的有丝分裂基因组重建，包括第一个对该属的研究和第二个对从自然环境中采集并永久保存的Corydoradinae标本的研究。barbatus有丝分裂基因组是一个16694碱基对(bp)的圆形分子，包含37个基因，其中22个是tRNA, 2个是rRNA, 13个是蛋白质编码基因和1个控制区(D-loop)。在atp酶亚基6和COIII基因之间发现了一个18个核苷酸的插入序列。大多数基因编码在重链上，而ND6和8个trna编码在轻链上。利用现有的其他有丝分裂基因组进行系统发育分析，证实了Callichthyinae和Corydoradinae的单系性，并表明barbatus种群形成了Corydoras nattereri + Corydoras paleatus的一个独立且关系更密切的分支。

期刊介绍： Neotropical Ichthyology is the official journal of the Sociedade Brasileira de Ictiologia (SBI). It is an international peer-reviewed Open Access periodical that publishes original articles and reviews exclusively on Neotropical freshwater and marine fishes and constitutes an International Forum to disclose and discuss results of original research on the diversity of marine, estuarine and freshwater Neotropical fishes. -Frequency: Four issues per year published only online since 2020, using the ‘rolling pass’ system, which posts articles online immediately as soon as they are ready for publication. A searchable and citable Digital Object Identifier (DOI) is assigned to each article immediately after online publication, with no need to await the issue’s closing. -Areas of interest: Biology, Biochemistry and Physiology, Ecology, Ethology, Genetics and Molecular Biology, Systematics. -Peer review process: The Editor-in-Chief screens each manuscript submitted to Neotropical Ichthyology to verify whether it is within the journal’s scope and policy, presents original research and follows the journal’s guidelines. After passing through the initial screening, articles are assigned to a Section Editor, who then assigns an Associate Editor to start the single blind review process.
