The multipartite mitochondrial genome of Cynanchum auriculatum (Gentianales: Apocynaceae).

ABSTRACT: Cynanchum auriculatum is a Chinese herbal medicine species in the family Apocynaceae. The mitochondrial genome of C. auriculatum has heteroplasmy and consists of two chromosomes (chromosomes I and II), the lengths of which are 614,836 and 426,495 nucleotides. The multipartite mitochondrial genome encodes 57 genes, including 37 protein-coding genes, 17 transfer RNA genes, and three ribosomal RNA genes. Including 44 overlapping genes, we identified 57 genes on chromosome I and 44 genes on chromosome II. A phylogenetic tree revealed that C. auriculatum is most closely related to Asclepias syriaca.

Molecular Discrimination of Cynanchum wilfordii and Cynanchum auriculatum by InDel Markers of Chloroplast DNA.

Project description:The tuber of Cynanchum wilfordii (Baekshuoh Radix in Korean) is an important medicinal herb in Korea and China; however, it is difficult to differentiate C. wilfordii from a related medicinal herb, C. auriculatum (Baishouwu Radix in Chinese). We sought to develop a molecular method that could be used to distinguish between the tubers of C. wilfordii and C. auriculatum. We aligned the chloroplast genome sequences (available in the NCBI database) of the two species and identified three species-specific insertion and deletion (InDel) sites in the trnQ-psbK, rps2-rpoC2, and psaJ-rpl33 intergenic spacer (IGS) regions. To confirm the presence of these three InDels and validate their use as markers, we designed three primer pairs to amplify the trnQ-psbK, rps2-rpoC2, and psaJ-rpl33 IGS regions. Polymerase chain reaction (PCR) amplification of the trnQ-psbK IGS region yielded a 249 bp fragment for C. wilfordii, and 419 bp fragment for C. auriculatum, whereas the rps2-rpoC2 IGS primers produced a 629 bp fragment from C. wilfordii and a 282 bp fragment from C. auriculatum. In the psaJ-rpl33 IGS region, allele fragments of 342 and 360 bp in length were amplified from C. wilfordii, whereas 249 and 250 bp fragment were amplified from C. auriculatum. We propose these three InDel markers as a valuable, simple, and efficient tool for identifying these medicinal herbs and will thus reduce adulteration of these herbal materials in commercial markets.

Selection of solvent for extraction of antioxidant components from Cynanchum auriculatum, Cynanchum bungei, and Cynanchum wilfordii roots.

Project description:In east Asia, "Baishouwu" has been used as an herbal drug and functional dietary supplement for hundreds of years. Actually, "Baishouwu" is the common name of the roots of Cynanchum auriculatum, Cynanchum bungei, and Cynanchum wilfordii. In the present study, roots of these three specie were extracted and then fractionated using petroleum ether (PE), dichloromethane (DCM), ethyl acetate (EA), and water. DPPH scavenging experiments revealed high antioxidant activity of DCM and EA fractions of C. bungei and the EA fraction of C. wilfordii. Treatments with these three fractions significantly reduced malondialdehyde content in heat-stressed Daphnia magna, validating in vivo antioxidant activity. Gas chromatography-mass spectrometer (GC-MS) analyses demonstrated that the chemical components of fractions extracted from C. bungei, C. bungei, and C. wilfordii were different. Further determination of total phenol and total flavonoids contents showed that DCM and EA fractions of C. bungei and EA fraction of C. wilfordii had much higher contents of total phenol and total flavonoids, which might be the reason to explain their strong antioxidant activity. Overall, the present study suggested that these three plants have different chemical components and biological activities. They could not be used as the same drug.

Transcriptome analyses revealed molecular responses of Cynanchum auriculatum leaves to saline stress.

Project description:Cynanchum auriculatum is a traditional herbal medicine in China and can grow in saline soils. However, little is known in relation to the underlying molecular mechanisms. In the present study, C. auriculatum seedlings were exposed to 3.75‰ and 7.5‰ salinity. Next, transcriptome profiles of leaves were compared. Transcriptome sequencing showed 35,593 and 58,046 differentially expressed genes (DEGs) in treatments with 3.75‰ and 7.5‰, compared with the control, respectively. Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses of these DEGs enriched various defense-related biological pathways, including ROS scavenging, ion transportation, lipid metabolism and plant hormone signaling. Further analyses suggested that C. auriculatum up-regulated Na+/H+ exchanger and V-type proton ATPase to avoid accumulation of Na+. The flavonoid and phenylpropanoids biosynthesis pathways were activated, which might increase antioxidant capacity in response to saline stress. The auxin and ethylene signaling pathways were upregulated in response to saline treatments, both of which are important plant hormones. Overall, these results raised new insights to further investigate molecular mechanisms underlying resistance of C. auriculatum to saline stress.

Genome size and identification of repetitive DNA sequences using low coverage sequencing in Hancornia speciosa Gomes (Apocynaceae: Gentianales).

Project description:Repetitive DNA is an important component of eukaryotic genomes, accounting for more than 90% of the genome size of some species, including mobile elements and satellite DNA sequences. The aim of study was to characterize the genome of Hancornia speciosa Gomes using C-value genome size estimate and repetitive DNA sequences analysis. The genome size estimate was obtained by flow cytometry and the repetitive DNA sequences were accessed using graph-based clustering. Evolutionary relationships among species of Apocynaceae was obtained using reads of Catharanthus roseus L., Rhayza stricta Decne, and Asclepias syriaca L. from the NCBI and analyzed by graph-based clustering. The genome size estimates in two botanical varieties showed 2C-values ranging from 0.88 to 1.08 pg, indicating small genome size. Clusters representing repeats making up at least 0.01% of the genome revealed the proportion of repetitive DNA ranging from 19.87% (H. speciosa) to 51.674% (A. syriaca), of which the mobile elements were more abundant. Satellite DNA sequences were not found in H. speciosa and R. stricta, while at least one satellite was detected in C. roseus and A. syriaca, suggesting that the LTR retrotransposon Ty3/Gypsy/Chromovirus may have replaced the satellite DNA in H. speciosa and R. stricta.

Complete plastid genome characterization and phylogenetic analysis of Pentasachme caudatum Wallich ex Wight (Gentianales: Apocynaceae) from Guangdong, China.

Project description:Pentasachme caudatum Wallich ex Wight is considered as one of the Asian enigmatic genera classified in the Asclepiadoideae (Apocynaceae). To determine its evolutionary relationship in the family, we sequenced and characterized the complete chloroplast genome of P. caudatum. The plastid genome of P. caudatum is 158,487 bp in length, containing a large single-copy (90,380 bp), a small single-copy (18,585 bp), and a pair of inverted repeats (24,761 bp). It has 127 annotated genes, consisting of 83 protein-coding, eight rRNA and 36 tRNA genes. Phylogenetic analysis using 76 protein-coding regions of the plastid genomes of related taxa showed that P. caudatum was resolved in a fully supported clade with Orthanthera albida. The newly sequenced P. caudatum provides essential genetic information that is useful for future phylogenetic studies in the family Apocynaceae.

Systematically fragmented genes in a multipartite mitochondrial genome.

Project description:Arguably, the most bizarre mitochondrial DNA (mtDNA) is that of the euglenozoan eukaryote Diplonema papillatum. The genome consists of numerous small circular chromosomes none of which appears to encode a complete gene. For instance, the cox1 coding sequence is spread out over nine different chromosomes in non-overlapping pieces (modules), which are transcribed separately and joined to a contiguous mRNA by trans-splicing. Here, we examine how many genes are encoded by Diplonema mtDNA and whether all are fragmented and their transcripts trans-spliced. Module identification is challenging due to the sequence divergence of Diplonema mitochondrial genes. By employing most sensitive protein profile search algorithms and comparing genomic with cDNA sequence, we recognize a total of 11 typical mitochondrial genes. The 10 protein-coding genes are systematically chopped up into three to 12 modules of 60-350 bp length. The corresponding mRNAs are all trans-spliced. Identification of ribosomal RNAs is most difficult. So far, we only detect the 3'-module of the large subunit ribosomal RNA (rRNA); it does not trans-splice with other pieces. The small subunit rRNA gene remains elusive. Our results open new intriguing questions about the biochemistry and evolution of mitochondrial trans-splicing in Diplonema.
