sp. nov. (Fabaceae, Hedysareae), a new species from the Qilianshan Mountains in Gansu, China.

(Fabaceae, Hedysareae) is described and illustrated from the Qilianshan Mountains in Gansu, China. This new species is similar to , but can be distinguished by its corolla being light purple to purple, standard 15-19 mm long, wings 14-16 mm long, keels 16-19 mm long, and the ovary and legume being glabrous. The new species can be easily distinguished from Ledeb.

Tension zone trapped by exogenous cline: Analysis of a narrow hybrid zone between two parapatric species (Fabaceae).

Hybrid zones have been widely highlighted for their interest in understanding evolutionary processes. It is generally accepted that hybrid zones can be maintained in a balance between dispersal and selection. However, the selective forces can either be endogenous (i.

The complete chloroplast genome of C. B. Clarke (Cyperaceae), an endemic species from China.

C. B. Clarke is a sedge with excellent ornamental characters, it is an important ecosystem stabilizer.

Why More Leaflets? The Role of Natural Selection in Shaping the Spatial Pattern of Leaf-Shape Variation in (Fabaceae) and Two Close Relatives.

Leaf shape exhibits tremendous diversity in angiosperms. It has long been argued that leaf shape can affect major physiological and ecological properties of plants and thus is likely to be adaptive, but the evolutionary evidence is still scarce. (Fabaceae) is polymorphic for leaf shape (1 leaflet, 1-3 leaflets, and 3 leaflets) and exhibits clinal variation in steppes of Nei Mongol, China.

The complete chloroplast genome sequence of Knuth (Primulaceae), an endangered species in China.

Knuth is an endangered species endemic to China. Its complete chloroplast genome was reported in this study for the first time. The whole chloroplast genome was 151, 443 base pairs in length with 131 genes, including 66 protein-coding genes, 37 tRNAs, and 4 rRNAs.

The complete chloroplast genome sequence of Bunge (Fabaceae).

The first complete chloroplast genome of Bunge is reported and characterized in this study. The whole chloroplast genome was 122,461 base pairs in length with 110 genes, including 76 protein-coding genes, 30 tRNAs, and 4 rRNAs. In addition, the intron was absent.

New morphological and DNA evidence supports the existence of Z. M. Mao (Calligoneae, Polygonaceae) in China.

Z. M. Mao, a species regarded as endemic to China, was thought to be nonexistent owing to a lack of scientific records.

Taxonomic revision of Chenopodiaceae in Himalaya and Tibet.

The composition of many Chenopodiaceae genera in different parts of Himalaya and Tibet has been insufficiently known or contradictory. A revision of the family in Himalaya including Bhutan, Nepal, parts of India (Himachal Pradesh, Jammu and Kashmir, Sikkim and Uttarakhand) and Tibet (Xizang, China) is presented for the first time. Altogether, 57 species from 20 genera are reported, including three species new to science (, and ).

Polycyclic polyprenylated acylphloroglucinol and phenolic metabolites from the aerial parts of Hypericum elatoides and their neuroprotective and anti-neuroinflammatory activities.

A phytochemical study on the aerial parts of Hypericum elatoides led to the isolation of a previously undescribed polycyclic polyprenylated acylphloroglucinol derivative, hyperelatone A, seven previously undescribed phenolic metabolites, hyperelatones B-H, along with ten known analogues. The structures of hyperelatones A-H were elucidated by 1D and 2D NMR spectroscopy, HRESIMS experiment, single-crystal X-ray diffraction and comparison of experimental and calculated ECD spectra, as well as chemical derivatization. All compounds were evaluated for their neuroprotective activity against hydrogen peroxide (HO)-induced cell injury in rat pheochromocytoma PC-12 cells and inhibitory effects on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in BV-2 microglial cells.

Isolation and characterization of microsatellite loci from (Fabaceae).

Premise Of The Study: Microsatellite primers were developed for a perennial legume from northern China, (Fabaceae), to investigate population genetic structure of this taxon, as well as potential hybridization events with closely related taxa in this genus.

Methods And Results: One hundred and five primer pairs were designed from Illumina sequence data and screened for suitability. Fifteen of these primer pairs were polymorphic, and these primers amplified tri-, tetra-, and pentanucleotide repeats with 10-56 alleles per locus.

Hyperelatosides A-E, biphenyl ether glycosides from , with neurotrophic activity.

Five new biphenyl ether glycosides, hyperelatosides A-E (1-5), one new benzoate glycoside, hyperelatoside F (6), along with nine known phenolic compounds (7-15), were isolated from the aerial parts of . Their structures were elucidated by 1D and 2D NMR spectroscopy and HRESIMS, as well as chemical derivatization. This is the first report of the identification of biphenyl ether glycosides as plant metabolites and their possible biosynthetic pathway is proposed.

Evolutionary response to the Qinghai-Tibetan Plateau uplift: phylogeny and biogeography of and tribe Thermopsideae (Fabaceae).

Previous works resolved diverse phylogenetic positions for genera of the Fabaceae tribe Thermopsideae, without a thoroughly biogeography study. Based on sequence data from nuclear ITS and four cpDNA regions (, , , ) mainly sourced from GenBank, the phylogeny of tribe Thermopsideae was inferred. Our analyses support the genera of Thermopsideae, with the exclusion of , being merged into a monophyletic Sophoreae.

Hedysarum L. (Fabaceae: Hedysareae) Is Not Monophyletic - Evidence from Phylogenetic Analyses Based on Five Nuclear and Five Plastid Sequences.

The legume family (Fabaceae) exhibits a high level of species diversity and evolutionary success worldwide. Previous phylogenetic studies of the genus Hedysarum L. (Fabaceae: Hedysareae) showed that the nuclear and the plastid topologies might be incongruent, and the systematic position of the Hedysarum sect.

Measurement of Magic Wavelengths for the ^{40}Ca^{+} Clock Transition.

We demonstrate experimentally the existence of magic wavelengths and determine the ratio of oscillator strengths for a single trapped ion. For the first time, two magic wavelengths near 396 nm for the ^{40}Ca^{+} clock transition are measured simultaneously with high precision. By tuning the applied laser to an intermediate wavelength between transitions 4s_{1/2}→4p_{1/2} and 4s_{1/2}→4p_{3/2}, the sensitivity of the clock transition Stark shift to the oscillator strengths is greatly enhanced.
