Characterization of the complete mitochondrial genome of Neolissochilus hendersoni (Herre, 1940) (Cypriniformes: Cyprinidae)

Abstract

The differentiation between Neolissochilus and Acrossocheilus species based only on morphology is ambiguous; however, phylogenetic analysis using their mitogenome sequences provides conclusive results. Here, the phylogenetic position of Neolissochilus hendersoni (Herre, 1940) was determined using its mitogenome data. Total DNA from N. hendersoni was sequenced using the Illumina NovaSeq6000 platform, and annotation of mitochondrial genes was performed using MITOS2. Phylogenetic trees were constructed using the complete mitogenomes of 16 fish species. The mitogenome of N. hendersoni was found to be 16584 bp long, containing two ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes, and three non-coding control regions. The genome showed a slight A + T bias (A + T = 56.46%). Most PCGs were found to be located on the L-strand. Results of the phylogenetic analysis showed that N. stracheyi is closely related to N. hendersoni . Our results will help to clarify the phylogenetic relationship between Neolissochilus and Acrossocheilus species.
