The complete chloroplast genome of Mitrasacme pygmaea (Loganiaceae).

ABSTRACT: The complete chloroplast genome of Mitrasacme pygmaea was sequenced and assembled for the first time. The chloroplast genome is 152,611 bp in length, containing a large single-copy (LSC) region of 83,881 bp and a small single-copy region (SSC) of 18,110 bp, separated by a pair of inverted repeats (IRs) of 25,310 bp. The genome contains 113 unique genes, including 79 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Among them, 15 genes have one intron each and 3 genes contain two introns. The overall GC content is 37.9%, while the corresponding values of LSC, SSC, and IR regions are 36.0%, 31.7%, and 43.4%, respectively. Phylogenetic analysis showed that M. pygmaea is sister to Gentiana tibetica and provided new insight into the evolution of Loganiaceae.

Characterization of the complete chloroplast genome of Pinus yunnanensis var. pygmaea.

Project description:Pinus Yunnanensis var. pygmaea (Fam: pinaceae; Gen: Pinus), is a mutant of Pinus yunnanensis. Franch. To contribute to its conservation, the complete chloroplast (cp) genome of P. yunnanensis var. Pygmaea was sequenced and assembled by high-throughput sequencing technology. The results show that P. yunnanensis var. pygmaea cp genome contained 101 genes, including 64 protein-coding genes, 33 tRNA genes, and four rRNA genes. The overall GC content of the cp genome is 38.50%. A phylogenetic tree reconstructed by 16 cp genomes reveals that P. yunnanensis var. pygmaea is most related with Pinus taiwanensis.

Complete chloroplast genome of Sedum sarmentosum and chloroplast genome evolution in Saxifragales.

Project description:Comparative chloroplast genome analyses are mostly carried out at lower taxonomic levels, such as the family and genus levels. At higher taxonomic levels, chloroplast genomes are generally used to reconstruct phylogenies. However, little attention has been paid to chloroplast genome evolution within orders. Here, we present the chloroplast genome of Sedum sarmentosum and take advantage of several available (or elucidated) chloroplast genomes to examine the evolution of chloroplast genomes in Saxifragales. The chloroplast genome of S. sarmentosum is 150,448 bp long and includes 82,212 bp of a large single-copy (LSC) region, 16.670 bp of a small single-copy (SSC) region, and a pair of 25,783 bp sequences of inverted repeats (IRs).The genome contains 131 unique genes, 18 of which are duplicated within the IRs. Based on a comparative analysis of chloroplast genomes from four representative Saxifragales families, we observed two gene losses and two pseudogenes in Paeonia obovata, and the loss of an intron was detected in the rps16 gene of Penthorum chinense. Comparisons among the 72 common protein-coding genes confirmed that the chloroplast genomes of S. sarmentosum and Paeonia obovata exhibit accelerated sequence evolution. Furthermore, a strong correlation was observed between the rates of genome evolution and genome size. The detected genome size variations are predominantly caused by the length of intergenic spacers, rather than losses of genes and introns, gene pseudogenization or IR expansion or contraction. The genome sizes of these species are negatively correlated with nucleotide substitution rates. Species with shorter duration of the life cycle tend to exhibit shorter chloroplast genomes than those with longer life cycles.

Complete chloroplast genome comparisons for Pityopsis (Asteraceae).

Project description:Pityopsis includes several regionally and one federally endangered species of herbaceous perennials. Four species are highly localized, including the federally endangered P. ruthii. The genus includes several ploidy levels and interesting ecological traits such as drought tolerance and fire-dependent flowering. Results from previous cladistic analyses of morphology and from initial DNA sequence studies did not agree with one another or with the infrageneric taxonomic classification, with the result that infrageneric relationships remain unresolved. We sequenced, assembled, and compared the chloroplast (cp) genomes of 12 species or varieties of Pityopsis to better understand generic evolution. A reference cp genome 152,569 bp in length was assembled de novo from P. falcata. Reads from other sampled species were then aligned to the P. falcata reference and individual chloroplast genomes were assembled for each, with manual gapfilling and polishing. After removing the duplicated second inverted region, a multiple sequence alignment of the cp genomes was used to construct a maximum likelihood (ML) phylogeny for the twelve cp genomes. Additionally, we constructed a ML phylogeny from the nuclear ribosomal repeat region after mapping reads to the Helianthus annuus region. The chloroplast phylogeny supported two clades. Previously proposed clades and taxonomic sections within the genus were largely unsupported by both nuclear and chloroplast phylogenies. Our results provide tools for exploring hybridity and examining the physiological and genetic basis for drought tolerance and fire-dependent flowering. This study will inform breeding and conservation practices, and general knowledge of evolutionary history, hybridization, and speciation within Pityopsis.

The complete chloroplast genome of Vaccinium oxycoccos (Ericaceae)

Project description:Abstract Vaccinium species have great significance as fruit crops due to their economic and food values. Here we report the chloroplast genome of V. oxycoccos. The chloroplast genome of V. oxycoccos was 177,088 bp in length with a GC content of 36.74%. LSC, SSC, and IR regions were 104,139 bp, 3031 bp, and 34,959 bp in length, respectively. The chloroplast genome contained 105 different genes, including 73 protein-coding genes, 4 rRNA genes, and 28 tRNA genes. The phylogenetic analysis indicated that V. oxycoccos was closely related to V. microcarpum in the family Ericaceae. This chloroplast genome not only enriches the genome information of Vaccinium, but also will be useful in the evolution study of the family Ericaceae.

The complete chloroplast genome of Malvaviscus penduliflorus (Malvaceae)

Project description:Abstract In this study, we assembled the complete chloroplast (cp) genome of Malvaviscus penduliflorus using high-throughput Illumina sequencing reads. The resulting plastome assembly displayed a typical quadripartite structure with a total length of 160,332 bp, containing a pair of inverted repeat regions (IRs) of 26,313 bp separated by a large single-copy region (LSC) of 88,750 bp and a small single-copy region (SSC) of 18,956 bp. The M. penduliflorus cp genome contained 128 genes, and its overall GC content was 36.96%. Phylogenetic analysis among M. penduliflorus and five other Malvaceae species demonstrated that M. penduliflorus was closely related to Urena procumbens and Hibiscus cannabinus. The M. penduliflorus cp genome presented in this study will lay a good foundation for further genetic and genomic studies of the genus Malvaviscus as well as Malvaceae.
