Mitogenome evolution in the Chlorophyceae is characterized by the acquisition of a reduced-derived pattern by the Chlamydomonadales + Sphaeropleales clade. Because no mitogenomes are available for the sister clade Oedogoniales + Chaetophorales + Chaetopeltidales, it remains unclear whether the common ancestor of chlorophycean green algae harbored a reduced-derived or ancestral-type mitogenome. The 70,191 and 46,765-bp mitogenomes reported here for Bulbochaete rectangularis var. hiloensis (Oedogoniales) and Stigeoclonium helveticum (Chaetophorales), respectively, shed light on this question. Both contain the same set of 41 conserved genes, a repertoire lacking numerous protein-coding genes but featuring all 27 tRNA genes typically found in ancestral-type mitogenomes.Acer ginnala is a woody Acer plant with high ornamental value. In the present study, the chloroplast genome of A. ginnala was determined, annotated, and analyzed phylogenetically. The total chloroplast genome was 156,184 bp in length, consisting of a large single-copy region (86,525 bp), a small single-copy region (18,947 bp), and two inverted repeat regions (25,356 bp). The complete chloroplast genome contains 133 genes, including 90 protein-coding genes, 36 transfer RNA (tRNA) genes, and 8 ribosomal RNA (rRNA) genes. The phylogenetic analysis based on the sequences of 49 common proteins from 25 species demonstrated a close relationship between A. ginnala and three others Acer plants species including A. truncatum, A. miaotaiense, and A.catalpifolium. This study will help to understand the phylogenetic position of A. ginnala in genus Acer.Hevea camargoana is a natural latex producing tropical plant and a close relative of H. brasiliensis, the primary commercial source of natural rubber. This study sequenced and analyzed the chloroplast genome of H. camargoana. The circular chloroplast genome of H. camargoana contains 161,291 bp with a GC content of 35.72%. This region contains two inverted repeat regions (26,819 bp), a large single-copy region (89,281 bp), and a small single-copy (18,372 bp) region in the complete chloroplast genome. A total of 134 genes were annotated, including 86 protein-coding genes, 36 transfer RNA genes, 8 ribosomal RNA genes, and 4 pseudogenes. The results showed that H. camargoana and H. brasiliensis were closely related, suggesting that H. selleck inhibitor camargoana may be used for the future variety improvement of rubber trees.In this study, I presented the chloroplast genome of Houttuynia cordata Thunb using BGISEQ-500 sequencing data. Its chloroplast genome is 160,226 bp in size. It contains a pair of inverted repeat regions of 26,853 bp, each separating a small single copy region of 18,340 bp and a large single copy region of 88,180 bp. Totally, 112 unique genes, including 78 protein coding genes, 30 tRNAs and 4 rRNAs, were identified and annotated in the chloroplast genome. Phylogenetic maximum likelihood analysis indicated that H. cordata Thunb is closest to Piper cenocladu.Protea kilimandscharica is endemic to the heath zone of Mt Kenya, restricted to the rocky slopes of the mountain. The complete chloroplast genome of P. kilimandscharica was determined by next-generation sequencing technology, with a total length of 158,657 bp. The cp genome encodes 115 unique genes, with four rRNA genes, 81 protein-coding genes (PCGs), and 30 tRNA genes. A 3.1 kb inversion was noted in the LSC. Phylogenetic analysis, based on 75 common protein-coding genes revealed P. kilimandscharica as sister to Macadamia integrifolia and Macadamia ternifolia.The complete mitogenome of Mitjaevia protuberanta (GenBank accession number MN627216) is 14,032 bp (AT 77.43%) in length, including 13 protein-coding, 22 transfer RNAs, and 2 ribosomal RNAs. All protein-coding genes used ATN as initiation codon except ND5 that used TTG as initiation codon, and TAA, TAG, and T were termination codons. We constructed a phylogenetic tree from 14 species (Hemiptera) based on the nucleotide sequence of 13 mitochondrial protein-coding genes. The phylogenetic analysis results showed that mitochondrial genome of M. protuberanta had the same characteristics as other Cicadellidae species.The mitochondrial genome of a dogielinotid amphipod, Haustorioides koreanus, was completely sequenced for the first time. The total mitogenome length of H. koreanus was 14,839 bp with 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. The phylogenetic tree confirmed that H. koreanus belongs to the families Hyalellidae in the same clade and to the suborder Senticaudata within Amphipoda. This is the first record of the complete mitochondrial genome sequence of the family Dogielinotidae.In this study, the chloroplast genome of Aster subulatus Michx, an important Chinese herb medical plant, has been presented using BGISEQ-500 sequencing. The chloroplast genome is 153,318 bp in size and is constituted of a pair of inverted repeat regions of 24,927 bp, a small single-copy region of 18,226 bp, and a large single-copy region of 85,238 bp. Totally, 102 unique genes, including 78 protein-coding genes, 20 tRNAs, and 4 rRNAs, were identified and annotated in the chloroplast genome. Phylogenetic maximum likelihood analysis indicated that A. subulatus Michx is closest to A. hersileoides.The complete chloroplast genome sequence of Elsholtzia densa was analysed. The results indicated that the size of the chloroplast genome was 149,095 bp in length with a large single-copy region (LSC) of 81,497 bp, a small single-copy region (SSC) of 17,364 bp, and a pair of inverted repeat (IR) regions of 25,117bp. The overall GC content of the cpDNA genome was 37.86%, while the corresponding values of the LSC, SSC, and IR regions were 35.96%, 31.92%, and 43.16%, respectively. A total of 132 functional genes were identified, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The maximum likelihood phylogenetic tree suggested that E. densa was closely related to the species in the family Labiatae.Hippophae tibetana adapted well to the unique plateau climate, diffused in the Qinghai-Tibetan Plateau-Himalayas. Here, we characterized the complete chloroplast genome of Hippophae tibetana. The chloroplast genome is found to be 155,810 bp in length with 36.67% GC contents. The chloroplast genome sequences encoding 131 genes, including 85 mRNA genes, 38 tRNA genes, and 8 rRNA genes. The phylogenetic trees further revealed that Hippophae tibetana is an independent species different from the model species Hippophae rhamnoides and chloroplast genome sequence showed a significant variation within and between closely related Hippophae genus.
