The complete mitochondrial genome of Chrysochir aureus was sequenced. The full length of the mitochondrial genome was 16,501 bp, including 13 protein-coding genes (PCGs), two ribosomal RNAs, 22 transfer RNA genes, a non-coding control region (CR) and one origin of replication on the light-strand (OL). The total nucleotide composition of mitochondrial DNA was 26.95% A, 29.99% C, 26.29% T, and 16.77% G. Twelve PCGs used the canonical ATG as their initiation codon, whereas COI gene started with an alternative start codon GTG. The mitochondrial genome of C. aureus described in this study could be a useful basis for management of this species and laid a foundation for further research involved with phylogenetic relationship within Sciaenidae.The root of Bupleurum marginatum var. stenophyllum (H. Wolff) Shan & Yin Li (Apiaceae), a new substitution for the popular Chinese medicinal material, Bupleuri Radix (Chai hu), is not easily distinguishable via traditional methods. The complete chloroplast genome sequence of B. marginatum var. stenophyllum was characterized using next-generation sequencing and the de novo assembly method. The complete genome was 155,576 bp in length and contained two inverted repeat (IR) regions of 26,311 bp, a large single-copy (LSC) region of 85,351 bp, and a small single-copy (SSC) region of 17,603 bp. It encoded 113 unique genes consisting of 79 protein-coding genes (PCGs), 30 transfer RNA genes, and four ribosomal RNA genes. Importantly, three genes (petB, petD and rps16) with small exon, and one trans-splicing gene (rps12) were correctly annotated. The overall GC content of the B. marginatum var. stenophyllum chloroplast genome is 37.7%. The phylogenetic analyses indicated that B. marginatum var. stenophyllum was closely related to B. marginatum. Moreover, many genetic information sites were available for distinguishing B. marginatum var. stenophyllum from the official 'Chai hu' plant sources, B. scorzonerifolium Willd. and B. chinense DC.The polyphagous cotton leafworm (Spodoptera littoralis) is one of the most destructive herbivorous insects worldwide. The present study reports the complete mitochondrial genome of S. littoralis collected from Egypt. The circular-mapping mitogenome was 15,408 bp in length with an overall A + T content of 81.1%, encoding a common set of 37 genes, including 13 protein-coding genes (PCGs), 22 tRNA genes, and two rRNA genes. Most PCGs were found to use conventional ATN as the start codon and TAN as the stop codon. The phylogenetic tree based on the nucleic acid sequences of 13 shared PCGs of 29 Noctuidae species revealed that S. littoralis and Spodoptera litura are sister species. The data in this study will be helpful to understand geographical genetic variations, phylogenetic relationships, and species identification of S. littoralis.Paramesotriton aurantius (Caudata Salamandridae) is a new species that found in southeastern China. Its complete mitochondrial genome (mitogenome) sequence was 16,313 bp in length with with A + T contents of 60.9%, and contained 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, one control region (D-loop), and one non-coding region. Our molecular tree showed that P. aurantius was positioned near P. hongkongensis, and formed a clade with other Paramesotriton species. The first complete mitogenome sequence of P. aurantius could provided fundamental data for resolving phylogenetic and genetic problems related to genus Paramesotriton.Cartilaginous fish are fascinating taxa, present in the folklore and art of many different cultures. Moreover, they display several unique anatomical, physiological, molecular, and behavioral characteristics making them extremely interesting from a biological perspective. Nevertheless, some crucial knowledge gaps remain, including phylogenetic relationships among extant species. Here, we produced the complete mitogenome sequence of the large-eyed rabbitfish, Hydrolagus mirabilis (Chimaeriformes). The complete mitogenome is 19,435 bp long and shows the same overall content, i.e. 13 protein-coding genes, 22 transfer RNA, and two ribosomal RNA genes, as all other examined Chondrichthyan mitogenomes. Phylogenetic reconstructions including 12 Holocephalan and three outgroup Elasmobranch mitogenomes place the H. mirabilis within the family Chimaeridae but revealed paraphyletic Hydrolagus and Chimaera, in line with a previous study, highlighting the importance for collecting additional molecular data to improve phylogenetic reconstruction in this group of vertebrates.The complete mitochondrial genome of Parastratiosphecomyia szechuanensis Lindner, 1954 was sequenced and analyzed in this study. The mitochondrial genome is 16,414 bp in length, including the 37 typical insect mitochondrial genes and a large control region. All PCGs end with complete termination codon TAA or TAG. Most PCGs initiated by standard start codon ATN, except for cox1 which starts with TCG. The phylogenetic analysis based on the nucleotide sequence data of 13 PCGs recovered the monophyly of Stratiomyidae and the sister relationship between Xylomyidae and Stratiomyidae.Coleoptera presents most of the cave fauna biodiversity, with several troglobite species belonging to the aquatic family Dytiscidae. However, very little is known on both genetic and genomic diversity traits of Neotropical cave beetles. Thus, here we present the complete mitochondrial genome sequence of five specimens of Desmopachria collected in a ferruginous cave from Serra dos Carajás in Parauapebas (Pará, Brazil, Eastern Amazon). Besides the general characteristics of the mitogenome of the analyzed specimens, we present their phylogenetic position within the family, considering the available genome sequences of different subfamilies within Dytiscidae.The complete chloroplast (cp) genome sequence of Actinidia arguta var. giraldii (Diels) Vorosch. was assembled and characterized by Illumina pair-end sequencing date. The complete plastid genome was 156,729 bp in length, containing a large single-copy (LSC) of 89,647 bp, and a small single-copy (SSC) of 22,482 bp, which was separated by a pair of 22,300 bp inverted repeat regions (IR). A total of 131 unique genes were identified, including 84 protein-coding genes, 39 tRNA genes, and 8 rRNA genes.  https://www.selleckchem.com/products/trastuzumab-deruxtecan.html  The phylogenetic position based on the chloroplast genome of 11 species showed that A. arguta var. giraldii was sister to Actinidia kolomikta.
