(Gentianales, Apocynaceae), a new species from Yunnan, China.

, a new species from Yunnan Province, China, is described and illustrated. is morphologically similar to , but can be easily distinguished from the latter by its succulent leaves that are 2‒4.5 cm long (vs.

Phylogenetic analysis and temporal diversification of the tribe Alsineae (Caryophyllaceae) with the description of three new genera, , and .

Alsineae are one of the most taxonomically difficult tribes in Caryophyllaceae and consist of over 500 species distributed in the northern temperate zone. Recent phylogenetic results have improved our understanding on the evolutionary relationships among Alsineae members. Nevertheless, there are still some unresolved taxonomic and phylogenetic problems at the generic level, and the evolutionary history of major clades within the tribe was unexplored to date.

Population Diversity Analysis Provide Insights into Provenance Identification of .

() is a valuable genuine herb. The source of this species is difficult to be identified by traditional methods including morphology, spectroscopy, and chromatography. We used the restriction site-associated DNA sequencing (RAD-seq) approach to perform the high-throughput sequencing of 24 provenances.

Phylogenetic estimation and morphological evolution of Alsineae (Caryophyllaceae) shed new insight into the taxonomic status of the genus .

is a monotypic genus in Caryophyllaceae endemic to China. The genus has been widely accepted since it was described in 1998, however its phylogenetic position within Caryophyllaceae has never been studied. In the present study, the whole plastid genome and nuclear ribosomal internal transcribed spacer (ITS) sequences of was obtained through genome skimming, and the phylogenetic position of the species was studied for the first time.

Complete plastome sequence of (L. f.) R. Br. (Apocynaceae).

is a remarkable genus with high horticultural ornamental value. In this study, we report and characterize the complete plastid genome sequence of The complete chloroplast genome was 176,340 bp in length, which includes a pair of inverted repeat regions (IRs) of 41,381 bp separated by a large single copy region (LSC) 91,281 bp and a small single copy region (SSC) 2,297 bp. Interestingly, IRs expanded into SSC, with the result that most of the genes in SSC were duplicated.

Characterization of the complete plastid genome of (Caryophyllaceae), an endangered medical herb endemic to south-western China.

is an endangered medical herb endemic to south-western China. In this study, the complete plastid genome of the species was characterized and assembled using the next-generation DNA sequencing method. The plastid genome is 153,978 bp in length, including a large single copy (LSC) region of 83,981 bp and a small single copy (SSC) region of 17,489 bp, which were separated by a pair of inverted repeat (IR) regions of 26,254 bp.

Complete plastid genome sequence of a medical herb, (L.) Kuntze (Lamiaceae).

The species is used medicinally and widely distributed from India, to China and the Indo-China Peninsula. The first complete plastid genome sequence of reported here was 151,900 bp long, with the large single copy (LSC) region of 83,144 bp, the small single copy (SSC) region of 17,556 bp and two inverted repeats (IRa and IRb) of 25,600 bp. The plastome contained 113 genes, including 79 protein-coding genes, 4 ribosomla RNA genes and 30 transfer RNA genes.

Genetic diversity and ex situ conservation of Loropetalum subcordatum, an endangered species endemic to China.

Background: Loropetalum subcordatum is an endangered species endemic to China that is characterized by narrow distribution, small population size, and delayed fertilization. However, the genetic diversity of the entire extant natural and ex situ populations has not been assessed to date. In this study, we evaluated the genetic diversity and structure of six natural populations and a single ex situ population (the only known ex situ population of L.

A molecular phylogeny of Aeridinae (Orchidaceae: Epidendroideae) inferred from multiple nuclear and chloroplast regions.

The subtribe Aeridinae, which contains approximately 90 genera, is one of the most diverse and taxonomically puzzling groups in Orchidaceae. In the present study, the phylogenetic relationships of Aeridinae were reconstructed utilizing five DNA sequences (ITS, atpI-H, matK, psbA-trnH, and trnL-F) from 211 taxa in 74 genera. The results of the phylogenetic analyses indicate that Aeridinae is monophyletic and that the subtribe can primarily be grouped into 10 clades: (1) Saccolabium clade, (2) Chiloschista clade, (3) Phalaenopsis clade, (4) Thrixspermum clade, (5) Vanda clade, (6) Aerides clade, (7) Trichoglottis clade, (8) Abdominea clade, (9) Gastrochilus clade, and (10) Cleisostoma clade.
