The genus Gentiana is the largest in the Gentianaceae family with ca. 400 species. However, with most species growing on the Qinghai–Tibet plateau, the processes of adaptive evolution and speciation within the genus is not clear. Also, the genomic analyses could provide important information. So far, the complete chloroplast (cp) genome data of the genus are still deficient. As the second and third sequenced members within Gentianaceae, we report the construction of complete cp sequences of… Expand
Comparative Chloroplast Genome Analyses of Species in Gentiana section Cruciata (Gentianaceae) and the Development of Authentication Markers
TLDR
This study indicated that cp genomes can provide more integrated information for better elucidating the phylogenetic pattern and improving discriminatory power during species authentication and primarily elucidated the phylogeny of Gentianales. Expand
Comparison of Four Complete Chloroplast Genomes of Medicinal and Ornamental Meconopsis Species: Genome Organization and Species Discrimination
TLDR
Comparative analysis of the four chloroplast genomes revealed five hotspot regions (matK, rpoC2, petA, ndhF, and ycf1), which could potentially be used as unique molecular markers for species identification and determine the evolutionary relationships among plant species in the Papaveraceae family.

The Complete Plastome Sequences of Seven Species in Gentiana sect. Kudoa (Gentianaceae): Insights Into Plastid Gene Loss and Molecular Evolution
The chloroplast (cp) genome is useful in the study of phylogenomics, molecular dating, and molecular evolution. Gentiana sect. Kudoa is a predominantly alpine flowering plant that is valued for itsExpand
Molecular Evolution of Chloroplast Genomes of Orchid Species: Insights into Phylogenetic Relationship and Adaptive Evolution
TLDR
The phylogenetic analysis based on whole cp genomes showed that C. appendiculata was closely related to C. striata var. Expand
Lineage‐specific plastid degradation in subtribe Gentianinae (Gentianaceae)
TLDR
This study illustrates that diverse degradation patterns shape the evolution of the plastid in this species‐rich plant group. Expand
Intra-individual heteroplasmy in the Gentiana tongolensis plastid genome (Gentianaceae)
TLDR
Botanists should reconsider the heredity and evolution of chloroplasts and be cautious with usingchloroplasts as genetic markers, especially in Gentiana, according to reports on rare intra-individual heteroplasmy in plastid genomes in plants. Expand
Comparative plastid genomics of Pinus species: Insights into sequence variations and phylogenetic relationships
TLDR
Phylogenetic analysis showed that Pinus species could be divided into two diverged clades comprising the subgenera Strobus and Pinus (double needles section), and molecular dating suggested that the genus Pinus originated approximately 130.38 Mya during the late Cretaceous. Expand
A morphometric comparison of three closely related species of Gentiana (Gentianaceae), endemic to the region of the Qinghai-Tibet Plateau
TLDR
This study targets the authentication of the three closely related species in Section Cruciata using the method of morphometric analysis of flower shape and showed that the parameters Rb (l1/w... Expand
Complete plastid genome of Gentiana trichotoma (Gentianaceae) and phylogenetic analysis
TLDR
The complete plastid genome of Gentiana trichotoma was determined and analyzed and showed that G. trichOToma clustered together with section Kudoa rather than section Cruciata. Expand
Complete Chloroplast Genome of Pinus massoniana (Pinaceae): Gene Rearrangements, Loss of ndh Genes, and Short Inverted Repeats Contraction, Expansion
TLDR
The results of phylogenetic analyses based on whole CPG sequences of 16 conifers indicated that the whole C PG sequences could be used as a powerful tool in phylogenetic analysis. Expand

The complete chloroplast genome of Gentiana straminea (Gentianaceae), an endemic species to the Sino-Himalayan subregion.
TLDR
The complete chloroplast genome sequence of G. straminea is reported, as the first sequenced member of the family Gentianaceae, to provide intragenic information for its conservation and contribute to research on the genetic and phylogenetic analyses of Gentianales and Asterids. Expand
Comparative Chloroplast Genomes of Camellia Species
TLDR
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. Expand
Molecular phylogeny and biogeography of Gentiana sect. Cruciata (Gentianaceae) based on four chloroplast DNA datasets
TLDR
The phylogenetic relationships between species within the Cruciata section confirmed the long-standing hypothesis that alpine plants in Central Asia and Europe originated from the QTP and/or West China and diversified extensively after the Pliocene when global temperatures decreased. Expand
Complete chloroplast genome sequences of Praxelis (Eupatorium catarium Veldkamp), an important invasive species.
TLDR
The complete Praxelis chloroplast genome sequence is reported and 14 markers containing greater than 2% parsimony-informative characters are identified, indicating that they are potential informative markers for barcoding and phylogenetic analysis. Expand
Thirteen Camellia chloroplast genome sequences determined by high-throughput sequencing: genome structure and phylogenetic relationships
TLDR
The results showed that, rather than functional constrains, it is the regional constraints that strongly affect sequence evolution of the cp genomes, and in a substantial improvement over prior studies, evolutionary relationships of the section Thea were determined on basis of phylogenomic analyses of cp genome sequences. Expand
Confirmation of Natural Hybrids between Gentiana straminea and G.siphonantha(Gentianaceae)Based on Molecular Evidence
TLDR
Most intermediate individuals were the natural hybrids between G.straminea and G.siphonantha, suggesting that the intraspecific diversification of DNA fragments within both parent species and their high variability in hybrid swarms probably resulted from chloroplast genome recombination and incomplete lineage sorting during the early stage of speciation origin of parent species.

[High-throughput pyrosequencing of the complete chloroplast genome of Magnolia officinalis and its application in species identification].
TLDR
The chloroplast genome can provide distinguishing differences to help identify Magnolia officinalis and its closely related plants, and is confirmed to be effective at the species and population level. Expand
Morphological, karyological and molecular delimitation of two gentians: Gentiana crassicaulis versus G. tibetica
TLDR
It is demonstrated that polyploidization had contributed to the intraspecific variation in G. crassicaulis and that the tetraploid individuals of this species showed morphological convergence with tetraPLoid G. tibetica, which blurred the morphological delimitations of the two species in southeast Xizang.

The monophyly and rapid evolution of Gentiana sect. Chondrophyllae Bunge s.l. (Gentianaceae): evidence from the nucleotide sequences of the internal transcribed spacers of nuclear ribosomal DNA

Genetic structure and differentiation of Gentiana atuntsiensis W. W. Smith and G. striolata T. N. Ho (Gentianaceae) as revealed by ISSR markers
TLDR
It is hypothesized that the two species arose from a rapid and recent speciation event induced mainly by geographical isolation, and the large population sizes, outcrossing breeding system, and small, light seeds that disperse widely may explain the genetic structure in both species. Expand
