Platanthera japonica (Thunb. ex A. Marray) Lindl belongs to the genus Platanthera within family Orchidaceae, is an endangered herbal species in the East Asia area. In this study, the complete plastome sequence (cpDNA) of P. japonica was determined by next-generation Illumina sequencing. The cpDNA of this herbal plant is 155,409 bp in size, with a pair of inverted repeat (IR) regions of 26,933 bp that separate a large single-copy (LSC) region of 84,049 bp and a small single-copy (SSC) region of 17,494 bp. The GC content in plastome is 36.9%, and the IR region (43.2%) is higher than that of the LSC and SSC region (34.4% and 29.7%, respectively), which is similar with other Orchidaceae plastomes. The assembled plastome encoded 133 genes, which included 38 tRNA genes, 8 rRNA genes, and 87 protein-coding genes. A total of 24 species were used to construct the phylogenetic relationships among P. japonica and other related species within Orchidaceae. The results showed that P. japonica is closely related to Platanthera chlorantha.Though the chloroplast genomes of several Vanda species have been sequenced, there is little information about the complete chloroplast (cp) genome of Vanda coerulescens. Herein, we established the cp genome of V. coerulescens. The chloroplast genome circle was 149,410 bp in length, with the structure of an 85,954 bp large single-copy (LSC) region and a 11,526 bp small single-copy (SSC) region, which separated by two inverted repeat (IRs) regions of 25,965 bp. It encoded 130 genes, including 74 protein-coding genes, 38 tRNA genes and 8 rRNA genes. The overall GC-content of the whole plastome is 36.7%, whereas the corresponding values of the LSC, SSC, and IR regions ranged from 28.2% to 43.1%. In addition, the phylogenetic analysis base on 20 chloroplast genomes of Orchidaceae indicates that V. brunnea is closely related to V. coerulescens. This announcement of the complete V. coerulescens cp genome sequence could provide valuable information for further genetic modification and phylogenetic study in Vanda genus.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.Nili-Ravi buffalo (Bubalus bubalis Linnaeus, 1758 breed Nili-Ravi, NRB) is a famous water buffalo breed in the world. It is the first time that the complete mitochondrial genome sequence of the NRB was reported. The total length of the mtDNA is 16,356 bp, It contains the typical structure, including 22 transfer RNA genes, 2 ribosomal RNA genes, 13 protein-coding genes, and 1 non-coding control region (D-loop region). The overall composition of the mtDNA was estimated to be 33.11% for A, 26.45% for T, 26.55% for C, and 13.89% for G. Phylogenetic analyses using neighbor-joining (N-J) computational algorithms showed that the analyzed 18 Ruminantia species are divided into four major clades Bovidae, Cervidae, Giraffidae, and Atilocapridae. In addition, our work confirmed that NRB has a close genetic relationship with B. bubalis isolate India 4.Nemania diffusa is a parasitic fungus of many plant species and causes large economic losses to the forestry industry. In the present study, the complete mitochondrial genome of N.  https://www.selleckchem.com/products/zotatifin.html  diffusa is first reported. The circular genome is 258,879 bp in length, containing 14 protein coding genes, 2 ribosomal RNA genes, 25 transfer RNA genes. The 258,879 bp long mtDNA of N. diffusa represents one of the largest sequenced fungal mitogenomes. The overall base composition is 34.4% A, 35.9% T, 14.0% G, 15.7% C and the content of GC is 29.7%. Phylogenetic analysis based on concatenated protein coding genes from 24 species in 8 orders was conducted using Bayesian inference (BI) method. Nemania diffusa is clustered in the order Xylariales and is more closely related to Annulohypoxylon stygium of Hypoxylaceae. This work facilitates the future study of molecular biology and evolution of xylariaceous fungi.Croton laevigatus grows as an evergreen tree or shrub with 15 meters height. It is distributed in the dense or open forests of Hainan province, China. Here, we report and characterize the complete plastome of C. laevigatus in an effort to provide genomic resources useful for promoting its systematics research. The plastome of C. laevigatus is found to possess a total length 162,515 bp with the typical quadripartite structure of angiosperms, contains two Inverted Repeats (IRs) of 26,866 bp, a Large Single-Copy (LSC) region of 90,234 bp and a Small Single-Copy (SSC) region of 18,549 bp. The plastome contains 113 genes, consisting of 79 unique protein-coding genes, 30 unique tRNA genes and four unique rRNA genes. The overall A/T content in the plastome of C. laevigatus is 64.10%. The phylogenetic analysis indicated that C. laevigatus is close to C. tiglium within Euphorbiaceae in this study. The complete plastome sequence of C. laevigatus will provide a useful resource for the conservation genetics of this species as well as for the phylogenetic studies of Euphorbiaceae.The complete mitochondrial genome sequences of giant jellyfish Chrysaora pacifica, a scyphozoan species inhabiting the Bohai Sea water in China, is firstly described and analyzed in this research. The mitogenome is a circular molecule 16,964 bp in length, including 13 protein-coding genes (Cox 1, Cox2, Atp 8, Atp 6, Cox 3, ND2, ND5, ND 6, ND3, ND4L,ND1,ND4, Cob), 2 tRNAs (trnW, trnM), 2 rRNA genes (small subunit RNA and large subunit RNA). The neighbor-joining (NJ) phylogenetic tree in the related species showed that C. pacifica is close to Chrysaora quinquecirrha.
