Dataset Information

Data on the polymorphic sites in the chloroplast genomes of seven perennial Helianthus species.

ABSTRACT: Data present the chloroplast genome sequences of seven wild perennial Helianthus species obtained by using the Illumina HiSeq and NextSeq platforms. Datasets not included in the primary publication [1] are a source for further evolutionary studies. In particular, the annotated chloroplast genomes and datasets of single nucleotide polymorphisms (SNP), simple sequence repeats (SSR), insertion and deletion polymorphisms (INDEL) for H.?tuberosus, H. salicifolius, H. pauciflorus, H. microcephalis, H.?hirsutus, H.?strumosus, and H.?grosseserratus are presented. The raw reads are available in Figshare (https://doi.org/10.6084/m9.figshare.12600155). The complete chloroplast genome sequences for the seven perennial Helianthus species are available on GenBank NCBI under the accessions MT302562.1 - MT302568.1; the remaining data are provided in this article.

Project description:BackgroundCamellia, comprising more than 200 species, is a valuable economic commodity due to its enormously popular commercial products: tea leaves, flowers, and high-quality edible oils. It is the largest and most important genus in the family Theaceae. However, phylogenetic resolution of the species has proven to be difficult. Consequently, the interspecies relationships of the genus Camellia are still hotly debated. Phylogenomics is an attractive avenue that can be used to reconstruct the tree of life, especially at low taxonomic levels.Methodology/principal findingsSeven complete chloroplast (cp) genomes were sequenced from six species representing different subdivisions of the genus Camellia using Illumina sequencing technology. Four junctions between the single-copy segments and the inverted repeats were confirmed and genome assemblies were validated by PCR-based product sequencing using 123 pairs of primers covering preliminary cp genome assemblies. The length of the Camellia cp genome was found to be about 157kb, which contained 123 unique genes and 23 were duplicated in the IR regions. We determined that the complete Camellia cp genome was relatively well conserved, but contained enough genetic differences to provide useful phylogenetic information. Phylogenetic relationships were analyzed using seven complete cp genomes of six Camellia species. We also identified rapidly evolving regions of the cp genome that have the potential to be used for further species identification and phylogenetic resolution.Conclusions/significanceIn this study, we wanted to determine if analyzing completely sequenced cp genomes could help settle these controversies of interspecies relationships in Camellia. The results demonstrate that cp genome data are beneficial in resolving species definition because they indicate that organelle-based "barcodes", can be established for a species and then used to unmask interspecies phylogenetic relationships. It reveals that phylogenomics based on cp genomes is an effective approach for achieving phylogenetic resolution between Camellia species.
