Philadelphus calvescens, belonging to the family Saxifragaceae, is a beautiful shrub with white fragrant flowers which is widely distributed in southwest China. In this study, we sequenced the complete chloroplast (cp) genome of P. calvescens to investigate its phylogenetic relationship in Saxifragaceae. Total length of the cpDNA genome was 157,237 bp, consisting of a large single copy (LSC) region of 86,481 bp, a small single copy (SSC) region of 18,728 bp, and a pair of inverted repeat regions (IRs, 26,014 bp). The genome contained 114 genes, namely 79 protein-coding genes, 31 tRNA genes, and 4 rRNA. The overall GC content was 37.8%. Phylogenetic analysis suggested that Philadelphus was closely related to Deutzia. The present study was the first report on complete cp genome of Philadelphus so it could afford important genetic information for further researches on the genus and related genera.The complete mitochondrial genome of the West African honey bee Apis mellifera adansonii consisted of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a control region. It was 16,466 bp and consisted of 84.7% AT nucleotides. This subspecies had a similar mitogenome to those of other southern African honey bees, namely A. m. scutellata, A. m. capensis, and A. m. monticola.The complete mitochondrial genome of Apis mellifera simensis was 16,523 bp long. The 13 protein-coding genes, two rRNAs, and 22 tRNAs resembled other Apis mitogenomes. The location of this Apis subspecies in our phylogenetic tree supported the hypothesis that this subspecies is distinct, and is most closely related to A. m. scutellata and A. m. monticola.Odontothrips loti (Haliday, 1852) is an important insect pest of Medicago sativa. In this study, the complete mitochondrial genome of O. loti (GenBank Accession number MN584901) was sequenced using Illumina HiSeq X Ten. The genome is 15,584 bp long and comprises 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNAs), 22 transfer RNA genes (tRNAs), and putative control region (CR). The nucleotide composition of O. loti mitochondrial genome is 41.18% of A, 34.45% of T, 12.72% of C, and 11.64% of G. The CR, located between tRNA-Thr and ND5, is 651 bp long. The length of 22 tRNAs range from 56 bp to 69 bp. The two rRNAs were located on the H-strand of which one was 1127 bp (16S rRNA) long and another was 732 bp (12S rRNA) long. Phylogenetic analysis showed that O. loti is closely related to Frankliniella intonsa and Frankliniella occidentalis. These new mitochondrial genome data are more complete and can be better used to provide a basis for studies of the mitochondrial evolution of Odontothrips.The two complete mitochondrial genomes were sequenced from the freshwater monogonont rotifer Brachionus rubens. TH5427 inhibitor The genome sequences were 12,041 bp and 13,793 bp in size, and the gene order and contents were identical to those of the freshwater rotifer B. rubens China, but were different in three tRNA-Arg, tRNA-Ile, and tRNA-Leu between both B. rubens mitochondrial genomes, while B. calyciflorus had peculiar gene order in mitochondrial DNA I. Of 12 protein-coding genes (PCGs), one gene (ND5) had incomplete stop codons. Furthermore, the start codon of ND4 and CO2 gene was ATT, while the start codon of other PCGs was ATG. The base composition of 12 PCGs in B. rubens mitogenome showed 22.5% for A, 46.5% for T, 16.3% for C, and 14.7% for G, respectively.Tainia dunnii is a terrestrial orchid with high ornamental value. Herein, we assembled the complete chloroplast genome of Tainia dunnii by next-generation sequencing technologies. The complete chloroplast genome sequence of Tainia dunnii is 158,305 base pairs (bp) in length, including a pair of inverted repeat regions (IRs, 25,244 bp), one large single-copy region (LSC, 86,819 bp), one small single-copy region (SSC, 20,998 bp). Besides, the complete chloroplast genome contains 136 genes in total, including 88 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Phylogenetic analysis showed that Tainia dunnii has the closest relationship with Calanthe davidii and Calanthe triplicata. Our study lay a foundation for further research of Tainia dunnii.Tainia cordifolia is a subtropical plant with significant ornamental value. Herein, we determined the complete chloroplast (cp) genome sequence of T. cordifolia using Illumina sequencing data. The whole cp genome is 158,089 bp in size, consisting of a pair of inverted repeats (IR 25,260 bp), a large single-copy region (LSC 86,876 bp), and a small single-copy region (SSC 20,693 bp). Plastid genome contains 136 genes, 88 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. What is more, a maximum-likelihood phylogenetic analysis demonstrated that T. cordifolia was most closely related to Oberonia japonica and Dendrobium salaccense. The cp genome will provide reference for the further investigation and research of T. cordifolia.The aim of this study was to determine the complete mitochondrial genome (mitogenome) and the phylogenetic location of the Palaemonetes sinensis. The mitogenome was 15,736 bp in length, containing 22 transfer RNA genes (tRNAs), 13 protein-coding genes (PCGs), 2 ribosome RNA genes (rRNAs), and a control region (CR). The overall nucleotide composition is as follows A, 35.69%; C, 21.66%; G, 12.39%; T, 30.26%. Nine and four PCGs were encoded on the heavy and light strands, respectively. Phylogenetic analysis suggested that P. sinensis shares a close relationship with Palaemon serenus and Palaemon capensis. These findings are helpful for better understanding the phylogenetic relationship among Caridea, as well as investigating the population genetics of P. sinensis in the future.The complete chloroplast genome of Cypripedium calceolus, a rare species in the family Orchidaceae was reported in this study. The genome size is 175,122 bp in length, and contains four sub-regions 97,486 bp of large single copy (LSC) and 22,260 bp of small copy (SSC) regions, separated by 27,688 bp of inverted repeat (IR) regions. A total of 133 genes were annotated, including 87 protein-coding genes, 38 tRNA genes and 8 rRNA genes. The GC content of this cp genome is 34.36%. Phylogenetic analysis revealed a close relationship between C. calceolus with C. japonicum and C. formosanum. This is the first complete cp genome for C. calceolus that would be useful for conservation and phylogenetic studies of this species.
