“…By conducting a comprehensive analysis of the mitogenome of a given insect species, we have the opportunity to perform intricate phylogenetic or population genetics studies and to identify potentially novel genes that may serve as valuable targets in future research efforts. The Lepidoptera order is the second-largest Insecta order and is composed of > 155,000 species of moths and butterflies 10 . Noctuoidea is the largest Lepidopteran sub-family, with > 42,400 species 11 .…”

In this study, we analyzed the complete mitochondrial genome (mitogenome) of Speiredonia retorta, which is a pest and a member of the Lepidoptera order. In total, the S. retorta mitogenome was found to contain 15,652 base pairs encoding 13 protein-coding genes (PCGs), 22 tRNAs, 2 rRNAs, as well as an adenine (A) + thymine (T)-rich region. These findings were consistent with the mitogenome composition of other lepidopterans, as we identified all 13 PCGs beginning at ATN codons. We also found that 11 PCGs terminated with canonical stop codons, whereas cox2 and nad4 exhibited incomplete termination codons. By analyzing the mitogenome of S. retorta using Bayesian inference (BI) and maximum likelihood (ML) models, we were able to further confirm that this species is a member of the Erebidae family.

“…In general, the length of this sequence is 15,308 bp (Genbank No: MK599146), containing two ribosomal RNA genes, 22 putative transfer RNA (tRNA) genes, 13 protein-coding genes, and an adenine (A) þ thymine (T)-rich region, consisted with previous studies (Sun et al 2016). The 12 PCGs initiated by ATN codons except for cytochrome c oxidase subunit 1 (cox1) gene that is seemingly initiated by the CGA codon as documented in other insect mitogenomes (Dai et al 2015;Sun et al 2017).…”

In the present study, the complete sequence of the mitochondrial genome (mitogenome) of Parasa tessellata (Lepidoptera: Limacodidae) is described. The mitogenome (15,308 bp) of P. tessellata encodes 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), and an adenine (A) þ thymine (T)-rich region. Its gene complement and order are similar to that of other sequenced lepidopterans. Phylogenetic analyses based on 13 PCGs using maximum likelihood (ML) and Bayesian inference (BI) revealed that P. tessellata resides in the Sphingidae family. This study provided the valuable evidence on phylogenetic relationship of the P. tessellata at the molecular level and essential resource for further research on this species.

“…Further, it has been shown that TLR9 is resided in the endoplasmic reticulum (ER) of immune cells and is translocated to the endosome upon detecting of unmethylated 2 -deoxyribose cytidine-phosphate-guanosine (CpG) DNA, a hallmark of microbial (e.g., bacterial) DNA [19,20]. Like the microbial genome, mitochondrial DNA also comprises of unmethylated CpG dinucleotides, the DNA act as a damage-associated molecular pattern that are endogenous molecules produced by cells undergoing abnormal cell death and are capable of stimulating the innate immune response in the host [21][22][23]. The class A, B, and C oligodeoxynucleotides (ODNs) are synthetic products (DNA nucleotides) comprising of unmethylated CpG nucleotide sequences like bacterial and mitochondrial DNA; however, they might have a different stimulatory effect on TLR9 activation [24].…”

During the last few years, mitochondrial DNA has attained much attention as a modulator of immune responses. Due to common evolutionary origin, mitochondrial DNA shares various characteristic features with DNA of bacteria, as it consists of a remarkable number of unmethylated DNA as 2′-deoxyribose cytidine-phosphate-guanosine (CpG) islands. Due to this particular feature, mitochondrial DNA seems to be recognized as a pathogen-associated molecular pattern by the innate immune system. Under the normal physiological situation, mitochondrial DNA is enclosed in the double membrane structure of mitochondria. However, upon pathological conditions, it is usually released into the cytoplasm. Growing evidence suggests that this cytosolic mitochondrial DNA induces various innate immune signaling pathways involving NLRP3, toll-like receptor 9, and stimulator of interferon genes (STING) signaling, which participate in triggering downstream cascade and stimulating to produce effector molecules. Mitochondrial DNA is responsible for inflammatory diseases after stress and cellular damage. In addition, it is also involved in the anti-viral and anti-bacterial innate immunity. Thus, instead of entire mitochondrial importance in cellular metabolism and energy production, mitochondrial DNA seems to be essential in triggering innate anti-microbial immunity. Here, we describe existing knowledge on the involvement of mitochondrial DNA in the anti-microbial immunity by modulating the various immune signaling pathways.
