Characterization of the complete chloroplast genome of Bupleurum hamiltonii N. P. Balakr. (Apiaceae) and its phylogenetic implications.

ABSTRACT: Bupleurum hamiltonii has a thin, wood, grayish-yellow root and is reputed to possess medicinal value. This study employs the de novo method using high-throughput sequencing data to assemble the complete chloroplast genome for this species. The total B. hamiltonii genome is 155,320 bp in length, containing a large single-copy region of 85,280 bp, a small single-copy region of 17,468 bp, a pair of inverted repeat regions of 26,286 bp, and has a GC content of 37.8%. The genome encodes 113 unique genes, of which there are 79 protein-coding, 30 tRNA, and four rRNA genes. In addition, 18 genes contained introns, petB, petD, and rpl16 are coded for by two exons, and rps12 is identified as a trans-splicing gene. Phylogenetic analysis results strongly suggest that B. hamiltonii is closely related to B. marginatum. This study provides valuable genetic information to facilitate reliable identification.

The complete mitochondrial genome sequences of Bupleurum falcatum (Apiales: Apiaceae).

Project description:Bupleurum falcatum has a long history of use in traditional oriental medicine. The first complete mitochondrial genome sequences of B. falcatum were 463,792 bp based on 494,582 aligned reads. A total of 51 genes was annotated including 32 protein-coding genes, 16 tRNA genes, and three rRNA genes. In a comparison of B. falcatum and carrot (Daucus carota) revealed that the former species has four exclusive genes, but lacks six genes present in the latter. The compositional structure and phylogenetic relationships indicated that the mitochondrial genome of B. falcatum is similar to that of D. carota.

Characterization of the complete chloroplast genome sequence of Dalbergia species and its phylogenetic implications.

Project description:The pantropical plant genus Dalbergia comprises approximately 250 species, most of which have a high economic and ecological value. However, these species are among the most threatened due to illegal logging and the timber trade. To enforce protective legislation and ensure effective conservation of Dalbergia species, the identity of wood being traded must be accurately validated. For the rapid and accurate identification of Dalbergia species and assessment of phylogenetic relationships, it would be highly desirable to develop more effective DNA barcodes for these species. In this study, we sequenced and compared the chloroplast genomes of nine species of Dalbergia. We found that these chloroplast genomes were conserved with respect to genome size, structure, and gene content and showed low sequence divergence. We identified eight mutation hotspots, namely, six intergenic spacer regions (trnL-trnT, atpA-trnG, rps16-accD, petG-psaJ, ndhF-trnL, and ndhG-ndhI) and two coding regions (ycf1a and ycf1b), as candidate DNA barcodes for Dalbergia. Phylogenetic analyses based on whole chloroplast genome data provided the best resolution of Dalbergia, and phylogenetic analysis of the Fabaceae showed that Dalbergia was sister to Arachis. Based on comparison of chloroplast genomes, we identified a set of highly variable markers that can be developed as specific DNA barcodes.

There are a total of 130 genes, coding for 85 proteins, 37 tRNAs, and 8 rRNAs. Phylogenetic relationship analysis based on 16 complete cp genome sequences exhibited that T. sagittata was phylogenetically closer to Menispermum dauricum and Stephania japonica.

Characterization of the Complete Chloroplast Genome and Phylogenetic Implications of Euonymus microcarpus (Oliv.) Sprague.

Project description:Euonymus microcarpus (Oliv.) Sprague, is a species of evergreen shrub of the genus Euonymus, family Celastraceae. Here, we extracted the genomic DNA from the leaves of E. microcarpus and constructed a paired-end library. The chloroplast genome of E. microcarpus was generated with the high-throughput sequencing by the illumina Hiseq X Ten platform and de novo assembly. The chloroplast genome had a quadripartite structure, containing a long single copy region with a size of 85,386 bp and a short single copy region with a size of 18,456 bp, separated by two inverted repeat regions of 26,850 bp. The chloroplast genome contained 133 genes identified in total, including 87 potential protein-coding genes, 38 transfer RNA genes, and eight ribosomal RNA genes. A total of 282 simple sequence repeats and 63 long repeats were found. Furthermore, the phylogenetic relationships inferred that E. microcarpus is sister to E. japonicus and E. schensianus. A comparison of the structure of the chloroplast genomes of eight Euonymus species suggests a nucleotide variability of the junction sites and a higher divergence of non-coding regions, compared to the coding regions. The original findings of the study serves as a good reference for chloroplast genome assembly and a valuable foundation for the genetic diversity and evolution of E. microcarpus.

The genome annotation predicted a total of 127 genes, including 82 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis with reported chloroplast genomes showed that T. scabra has a close genetic relationship with Anthriscus cerefolium.
