Project description:In this study, we determined the complete mitochondrial genome of Neolissochilus heterostomus. The genome is 16,585 bp in length, including 2 ribosomal RNA genes, 13 proteins-coding genes, 22 transfer RNA genes, and two non-coding control regions. Sequence analysis showed that the overall base composition of N. heterostomus is T 24.8%, C 27.7%, A 31.7%, and G 15.8%. The sequence is a slight A + T bias of 56.5%, which is similar to other fishes. We describe a phylogenetic analysis of 16 species of Cypriniformes based on the complete mitochondrial genome, and the result showed that N. stracheyi is most closely related to N. heterostomus. This mitogenome sequence data would play an important role in the investigation of phylogenetic relationship of the Cyprinidae.
Project description:Neolissochilus stracheyi Day 1871 is a rare specie of fish inhabit clear forest streams and rivers. In order to discuss the phylogenetic position of N. stracheyi, the mitochondrial genome was obtained by sequencing. The genome was 16,587 bp in length with an accession number OM203155. The AT contents were 56.59%. The location and composition of genes are consistent with published Cyprinids containing 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 main non-coding regions. Sequence analysis showed that the mitochondrial genome of N. stracheyi has high sequence homology with other cyprinid fishes. Phylogenetic tree results showed that N. stracheyi is most closely related to Neolissochilus heterostomus. The mitochondrial sequence is of great significance for fish conservation, taxonomic status and resource exploitation.
Project description:In this study, the complete mitochondrial genome of Neolissochilus benasi has been determined by polymerase chain reaction method for the first time. The overall base composition of N. benasi mitogenome is 31.8% for A, 27.4% for C, 15.9% for G and 25.0% for T. The percentage of G + C content is 41.3%. The mitogenome is a circular DNA molecule of 16 583 bp in length with a D-loop region and contains 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes and 13 protein-coding genes. The mitochondrial genome sequencing for N. benasi in this study provides important molecular data for further evolutionary analysis for Cyprinoidea.
Project description:The complete mitochondrial genome of the near threatened mahseer fish, Neolissochilus hexastichus, was characterized for the first-time using Ion Torrent NGS platform. The total length of the mitogenome was 16,538 bp including a standard set of 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), 13 protein-coding genes and a non-coding control region. Twenty-eight of the 37 genes are located on the light strand and, the remaining nine genes are situated on the heavy strand. Phylogenetic analysis showed the sister relationship between N. hexastichus and N. hexagonolepis. The mitogenome could be useful for phylogenetics, population genetics, and conservation of the mahseers.
Project description:In this paper, we first report the complete mitochondrial genome of Neolissochilus soroides. The main purpose of this study was to determine the mitochondrial genome and phylogenetic status of N. soroides. The length mitogenome was 16584 bp, containing 2 ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes, and 3 non-coding control regions. The genome showed a slight A + T bias (A + T = 56.47%). 12 genes (ND1, COX2, ATP6, ND4L, ND5, ND6, ND2, ATP8, ND3, ND4, Cytb, COX3) start with ATG codon, besides one gene (COX1) start with GTG codon. Six genes (ND1, COX1, ATP6, ND4L, ND5, ND6) end with a TAA codon, 3 genes (ND2, ATP8, ND3) end with a TAG codon, and four genes (COX2, ND4, Cytb, COX3) end with the TA or T codon. The phylogenetic analysis showed that N. soroides was closely related to N. hendersoni. The mitogenome could have important implications for phylogeny, population genetics, and conservation of the N. soroides.
