Abstract
The Chilo infuscatellus (Lepidoptera: Pyralidae) is a significant pest of sugarcane in China. The genome-level characteristics of this pest are important genetic resources for identification, phylogenetic analysis, and even management. In the present study, the complete mitogenome of C. infuscatellus was sequenced and characterized. The assembled mitochondrial genome is 15,252 bp in length and includes 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs), and an A + T-rich region. Except for the CGA codon for the cox1 gene, the PCGs are initiated with ATN codons (ATG, ATT, and ATA). These PCGs are terminated with TAA or an incomplete termination codon of a single T. Except for the loss of the "DHU" arm for trnS1, the tRNA genes were folded into the typical cloverleaf structure. The A + T-rich region has a high AT content of 96.19% and contains the motifs "ATAGA" and "ATTTA", as well as a 19 bp poly-T stretch and microsatellite regions. The C. infuscatellus mitogenome exhibits a conserved gene order among lepidopteran insects, with a rearrangement of the trnM gene compared to the ancestral insect gene order. Phylogenetic analysis based on the 13 PCGs using Bayesian inference (BI) and maximum likelihood (ML) methods confirmed the monophyly of Pyralidae and Crambidae within Pyraloidea. The relationships between subfamilies in Pyralidae can be described as (Galleriinae + (Phycitinae + (Pyralinae + Epipaschiinae))). The "PS clade" and "non-PS clade" were formed within the family Crambidae. These findings provide valuable genetic resources for the identification, phylogenetic analysis, and management of sugarcane borers, contributing significantly to our understanding of the phylogeny of Pyraloidea insects and their evolution.

Mitochondrial DNA B Resour 2023; 8:1401-1405. [PMID: 38130731 PMCID: PMC10732176 DOI: 10.1080/23802359.2023.2292745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 12/04/2023] [Indexed: 12/23/2023] Open
Abstract
We performed the first sequencing of the complete mitogenome of Botyodes diniasalis by high-throughput sequencing. A circular DNA molecule of 15,219 bp in size, encoding 2 rRNAs, 22 tRNAs, and 13 PCGs, contains a non-coding AT-rich region. The overall nucleotide composition of the genome is A (39.5%), T (41.3%), C (11.3%), and G (7.8%). Phylogenetic analysis based on mitogenomic data suggest that the species B. diniasalis has a close evolutionary relationship with B. principalis in Margaroniini. The complete mitogenome of B. diniasalis will serve as a valuable resource for future studies on evolution, taxonomy, genetic conservation, and utilization of Botyodes.

Animals (Basel) 2023; 13:3841. [PMID: 38136877 PMCID: PMC10740543 DOI: 10.3390/ani13243841] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 12/01/2023] [Accepted: 12/02/2023] [Indexed: 12/24/2023] Open
Abstract
The elongate loach is an endemic fish in China. Previous studies have provided some insights into the mitochondrial genome composition and the phylogenetic relationships of the elongate loach inferred using protein-coding genes (PCGs), yet detailed information about it remains limited. Therefore, in this study we sequenced the complete mitochondrial genome of the elongate loach and analyzed its structural characteristics. The PCGs and mitochondrial genome were used for selective stress analysis and genomic comparative analysis. The complete mitochondrial genome of the elongate loach, together with those of 35 Cyprinidae species, was used to infer the phylogenetic relationships of the Cobitidae family through maximum likelihood (ML) reconstruction. The results showed that the genome sequence has a full length of 16,591 bp, which includes 13 PCGs, 22 transfer RNA genes (tRNA), 2 ribosomal RNA genes (rRNA), and 2 non-coding regions (CR D-loop and light chain sub-chain replication origin OL). Overall, the elongate loach shared the same gene arrangement and composition of the mitochondrial genes with other teleost fishes. The Ka/Ks ratios of all mitochondrial PCGs were less than 1, indicating that all of the PCGs were evolving under purifying selection. Genome comparison analyses showed a significant sequence homology of species of Leptobotia. A significant identity between L. elongata and the other five Leptobotia species was observed in the visualization result, except for L. mantschurica, which lacked the tRNA-Arg gene and had a shorter tRNA-Asp gene. The phylogenetic tree revealed that the Cobitidae species examined here can be grouped into two clades, with the elongate loach forming a sister relationship with L. microphthalma. This study could provide additional inferences for a better understanding of the phylogenetic relationships among Cobitidae species.
