Torreya parvifolia (Torreya, Taxaceae) is endemic in Sichuan, China. It consisted of an extremely small population with less than 100 wild individuals. In this study, the complete chloroplast genome of T. parvifolia was assembled using the Illumina data. The complete chloroplast genome of T. parvifolia is 137,106 bp in length. The genome consists of 119 genes in total, including 82 protein-coding genes (PCGs), 4 ribosomal RNA (rRNA) genes, and 33 transfer RNA (tRNA) genes. Phylogenetic analysis indicated that T. parvifolia was closely related to T. fargesii, T. nucifera, and T. fargesii var. yunnanensis with strong support.Saccostrea echinata is a rock perched oyster with wide distribution and tremendous potential for commercial mariculture. However, the taxonomy of this genus is confused. In this study, we described the complete mitochondrial genome of medium-sized form of Saccostrea echinata. The genome is 16,282 bp in length, encoding the standard set of 12 protein-coding genes (PCGs), 23 tRNA genes, and two rRNA genes, with circular organization. The overall base composition of the whole mitochondrial genome was A (26.78%), T (36.64%), G (21.99%), and C (14.59%) with an AT bias of 63.42%. The longest PCG of these species was ND5, whereas the shortest was ND4L.Populus euphratica Oliv., one of tall arbors growing in desert areas, has great stress resistance. The complete chloroplast genome was reported in this study using the PacBio Sequel Platform. The chloroplast genome with a total size of 157,881 bp consisted of two inverted repeats (IRs) (27,666 bp) separated by a large single-copy region (85,906 bp) and a small single-copy region (16,643 bp). Further annotation revealed the chloroplast genome contains 111 genes, including 77 protein-coding genes, 30 tRNA genes, and four rRNA genes. The information of the chloroplast genome will be useful for study on the evolution of P. euphratica in the future.The complete chloroplast genome of Androsace mariae was sequenced and assembled. It is a circular form genome of 151,958 bp in length, which was separated into four distinct regions, a large single-copy (LSC) of 83,292 bp, a small single-copy region (SSC) of 16,744 bp, two inverted repeats (IR) of 25,961 bp. After annotation, a total of 133 genes were predicted, of which, 87 were encoded proteins, 8 rRNA, and 37 tRNA. The evolutionary history, inferred using the neighbour-joining method, indicates that A. mariae was grouped within Primulaceae, and comprised a clade with other three species in Androsace, Androsace paxiana, Androsace laxa and Androsace bulleyana, with 100% bootstrap value.In this study, the complete chloroplast genome of Chaetoceros muellerii was sequenced by using PacBio sequencing platform. The chloroplast genome was 116,284 bp in length, harboring a large single copy (LSC) region of 61,946 bp, a small single copy (SSC) region of 39,308 bp, and a pair of inverted repeats (IR) regions of 7515 bp. The overall GC content was 30.86%. The chloroplast genome of C. muellerii contained 131 genes in total, including 95 protein-coding genes, 30 transfer RNA (tRNA) genes and 6 ribosomal RNA (rRNA) genes. The phylogenetic analysis revealed that C. muellerii was closely related to Chaetoceros simplex with 100% bootstrap values. This study will contribute to the phylogenetic and taxonomic analysis of species in the family Chaetoceroceae.The African armyworm, Spodoptera exempta, is an episodic migratory crop pest with an expanding distribution worldwide. This is the first report of the circular mitochondrial genome of S. exempta, with a length of 15,457 bp and an A + T content of 81.7%. It encoded a common set of 37 genes, including 13 protein-coding genes (PCGs), 22 tRNA genes, and two rRNA genes, and contained a putative control region of 379 bp (94.7% in A + T proportion). The maximum-likelihood phylogenetic tree based on the complete mitogenome demonstrated that five species belonging to the Spodoptera genus formed one clade, in which S. exempta was the most isolated branch, followed by Spodoptera exigua. This data will contribute for the identification and phylogenetic analyses of S. exempta, providing useful information for its comprehensive control.Bryophyllum daigremontianum is a very important traditional medicine and ornamental plant. Although Bryophyllum and Kalanchoe have been supported to form a clade, however, lack of chloroplast genomic severely hinders our understanding the phylogenetic relationships between them. In this study, the complete chloroplast genome of B. daigremontianum is first presented. It is 150,058 bp in length consisted a large single-copy (LSC, 82,164 bp) and a small single-copy (SSC, 17,042bp) separated by a pair of inverted repeats (IR, 25,426 bp) including 86 protein-coding genes, 37 tRNA, and 8 rRNA. Phylogenetic analysis supported that B. daigremontianum was closer to K. tomentosa than other species, which showed that chloroplast genome sequences offer a useful resource for future phylogenetic studies of Kalanchoe and Bryophyllum species.Alloteropsis is a widely-distributed genus with C3 and C4 photosynthetic species belonging to the Poaceae family. This study characterized the complete chloroplast genomes of two Alloteropsis species from Chinese mainland, i.e. Alloteropsis semialata with C4 photosynthetic type and Alloteropsis cimicina with C3 photosynthetic type. The chloroplast genomes of A. semialata and A. cimicina are 138,188 bp and 139,335 bp in length, with 38.48% and 38.59% GC contents, respectively. These two chloroplast genomes contain the same number of genes, i.e. 107 unique genes including 27 tRNA, 4 rRNA, and 76 protein-coding genes. Phylogenomic analysis confirmed the species identity of A. semialata and A. cimicina and supported a close relationship of Alloteropsis with species of Setaria and Panicum in grass family.Stephanandra incisa is a typical discontinuous distribution species in the eastern part of the subspecies with a high economic and ecological value. In this study, we have obtained the complete chloroplast genome of S. incisa using high-throughput sequencing. The chloroplast genome length was 159,583 bp, the AT content was 63.7%, while the large single copy and a small single copy area were 88,018 bp and 18,817 bp, respectively. It contains 131 genes, including 86 protein-coding genes, 37 transfer RNA genes, and eight ribosomal RNA genes. A maximum-likelihood phylogenetic tree supported the fact that S. selleck inhibitor incisa is closely related to Pyracantha fortuneana and Amelanchier sinica, which is consistent with the taxonomic view.
