The complete chloroplast genome sequence of Sphagneticola trilobata (Asteraceae).

ABSTRACT: Sphagneticola trilobata is one of the world's worst invasive alien species. The paucity of genetic information for this species has made it difficult for studies on the underlying genetic mechanism of its invasiveness. Herein, we report the de novo chloroplast genome assembly of S. trilobata using Illumina whole-genome sequencing data. The chloroplast genome was 151,939?bp in length, with a large single copy (LSC) region of 83,405?bp, a small single copy (SSC) region of 18,448?bp, separated by two inverted repeat (IR) regions of 25,044?bp each. A total of 134 genes were annotated for the chloroplast genome assembly, including 86 protein-encoding genes. Phylogenetic analysis suggested close relationship between S. trilobata and Eclipta prostrata.

Characterization of the complete chloroplast genome sequence of Sphagneticola calendulacea (Asteraceae).

Project description:Sphagneticola calendulacea is a valuable medicinal herb. With the spread of a congeneric invasive species Sphagneticola trilobata in South China, the already vulnerable S. calendulacea populations are being threatened further by natural hybridization with the invading species. In this study, we assembled and characterized the complete chloroplast genome of S. calendulacea as a resource for future studies on this species. The chloroplast genome was 151,748?bp in size, with a large single-copy (LSC) region of 83,270?bp, a small single-copy (SSC) region of 18,348?bp, separated by two inverted repeat (IR) regions of 25,065?bp each. A total of 134 genes were predicted. Phylogenetic analysis showed close relationship between S. calendulacea and Eclipta prostrata within the Heliantheae tribe.

The complete chloroplast genome sequence of Tussilago farfara (Asteraceae).

Project description:Tussilago farfara is a member of the family Asteraceae. In this paper, we reported the complete chloroplast (cp) genome sequence of T. farfara. The results showed that T. farfara complete chloroplast genome comprises 151,325 bp, containing a largen single copy (LSC) region of 83,370 bp, a small single copy (SSC) region of 18,273 bp, and a pair of inverted repeats (IRs) region of 24,841 bp. The genome has a GC content of 37.4%. The LSC, SSC, and IR regions represent 35.5%, 30.6%, and 43.0% of the T. farfara chloroplast genome length. We annotated 132 genes, comprising 87 protein-coding genes (PCGs), eight rRNA genes, and 36 tRNA genes. A phylogenetic analysis based on 31 cpDNA genomes suggested that the T. farfara is closely related to Farfugium japonicum.

The complete chloroplast genome sequence of Neopallasia pectinata (Asteraceae).

Project description:The complete chloroplast (cp) genome of Neopallasia pectinata was sequenced and analyzed in this study. It was 150,766 bp in length and has a typical circular structure, including a large single copy (LSC) with 82,605 bp, two inverted repeats (IRs) with 24,944 bp, and a small single copy (SSC) with 18,273 bp. The phylogenetic analysis of N. pectinata and its related taxa was conducted depended on the complete cp-genome sequences. The maximum likelihood tree indicates a close relationship between Chrysanthemum and Neopallasia. The cp-genome of N. pectinata is useful for future phylogenetic studies of Asteraceae.

Responses of Sphagneticola trilobata, Sphagneticola calendulacea and Their Hybrid to Drought Stress.

Project description:Sphagneticola trilobata is an invasive plant in South China. A hybrid between S. trilobata and Sphagneticola calendulacea (a native related species) has also been found in South China. The drought resistance of S. calendulacea, S. trilobata and their hybrid was studied in this paper. Under drought stress, the leaves of S. trilobata synthesized more abscisic acid (ABA) than those of the other species to reduce stomatal opening and water loss. The activities of antioxidant enzymes were the highest in S. trilobata and the lowest in S. calendulacea. The leaves of S. calendulacea suffered the most serious damage, and their maximum photochemical efficiency was the lowest. RNA-sequencing ware used to analyze the expression levels of genes in ABA, antioxidant enzyme, sugar and proline synthesis and photosynthesis pathways. Further real-time PCR detection verified the RNA-sequence results, and the results were in accordance with the physiological data. The results showed that S. trilobata was the most drought tolerant, and the drought tolerance of the hybrid did not show heterosis but was higher than S. calendulacea. Therefore, compared with S. trilobata and the hybrid, the population number and distribution of S. calendulacea may be less in arid areas.

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.
