Human activities have shaped large-scale distributions of many species, driving both range contractions and expansions. Species differ naturally in size, with small-range species concentrated particular geographic areas potentially deviating ecologically from widespread species. Hence, species' responses to human may be influenced by their sizes, but if how this happens are poorly understood. Here, we use a comprehensive distribution database modeling examine affected the extent which 9,701...
Thirteen new species are formally described:
Abstract Aim The phylogenetic constraint hypothesis of flowering phenology states that closely related species flower at similar times the year. We test this for C hinese angiosperm flora and assess additional effects growth form, deciduousness, pollination mode fruit type. further examine whether conservatism tends to increase from tropical temperate latitudes. Location hina. Methods midpoint time 19,631 present in hina was compiled. signal evaluated whole country using B lomberg K ‐value...
Porcine reproductive and respiratory syndrome (PRRS) is an economically important disease of swine that caused by PRRS virus (PRRSV). In this study, we established a fluorescence assay for highly sensitive detection PRRSV through integration the reverse transcription–recombinase polymerase amplification (RT-RPA)-coupled Cas12a system with optical property single stranded DNA–fluorescently quenched (ssDNA-FQ) reporter. This technique can achieve isothermal visual in 25 min. particular,...
In long germ embryos, all body segments are specified simultaneously during the blastoderm stage. contrast, in short only anterior stage, leaving rest of plan to be later. The striking embryological differences between and segmentation imply fundamental patterning at molecular level. To gain insights into mechanisms insects, we have investigated role homologue Drosophila gap gene hunchback ( hb ) a insect Locusta migratoria manilensi by paternal RNA interference (RNAi). Phenotypes resulting...
ABSTRACT Various strains of entomopathogenic fungus Metarhizium flavoviride are potential insect control agents. However, there few systematic studies on their pathogenicity against larvae pests in the family Scarabaeidae. This study evaluates M. Ma130821 Metabolus flavescens Brenske feeding maize and tobacco, respectively, examines infection process aspects host immunological response. The present results showed that caused 76.67%–100.00% mortality within 18 days. When hyphal bodies...
Cycloviolacin H4, a new macrocyclic miniprotein comprising 30 amino acid residues, was isolated from the underground parts of Australian native violet Viola hederaceae. Its sequence, cyclo-(CAESCVWIPCTVTALLGCSCSNNVCYNGIP), determined by nanospray tandem mass spectrometry and quantitative analysis. A knotted disulfide arrangement, which designated as cyclic cystine knot motif characteristic to all known cyclotides, is proposed for stabilizing molecular structure folding. The cyclotide...
Abstract Aminolevulinic acid ( ALA )‐mediated protoporphyrin IX (Pp ) production is being explored for tumor fluorescence imaging and photodynamic therapy PDT ). As a prodrug, converted in heme biosynthesis pathway to Pp with fluorescent photosensitizing properties. To better understand the role of enzymes ‐mediated efficacy, we used lentiviral sh RNA silence expression porphobilinogen synthase PBGS ), deaminase PBGD ferrochelatase FECH SkBr3 human breast cancer cells. are first two...
In this paper, Sedum xunvense is described as a new species from Zhejiang, Southeast China. morphologically similar to S. formosanum, but the latter differs in clustered and robust stems (vs. solitary, slender), green or slightly red smooth inflorescence rachises purple-red ribbed), thick succulent leaves thin), yellow anthers reddish-brown), erect follicles oblique), found dry habitats rock crevices damp ravines, rocks mossy thickets). A reconstructed ML phylogeny of Sedum, based on nrITS...
Bioassay-guided fractionation of EtOH extract the roots Scrophularia ningpoensis Hemsl. resulted in isolation three new iridoid glycosides, i.e., 6''-O-caffeoylharpagide (1), 6''-O-feruloylharpagide (2), and 6''-O-beta-glucopyranosylharpagoside (3), five aromatic 2-(3-hydroxy-4-methoxyphenyl)ethyl O-alpha-arabinopyranosyl-(1-->6)-O-alpha-rhamnopyranosyl-(1-->3)-O-beta-glucopyranoside (4), phenyl O-beta-xylopyranosyl-(1-->6)-O-beta-glucopyranoside (5), 3-methylphenyl (6), 6-O-cinnamoyl...
Cycads represent one of the most ancestral living seed plants as well threatened plant groups in world. South China is a major center and potential origin Cycas , rapidly diversified lineage cycads. However, genomic-wide diversity remains poorly understood due to challenge generating genomic markers associated with their inherent large genomes. Here, we perform comprehensive conservation study based on restriction-site DNA sequencing (RADseq) data six representative species China....
Abstract Since the inception of genetic investigations into origin Dryopteris species belonging to D. subg. Erythrovariae in East Asia, around 20 taxa with hybrid ancestry have been identified. Among these species, some arisen from distant interspecific hybridization events. In this study, we describe and illustrate two newly discovered hybrids China: parabissetiana sp. nov., a triploid ×tiantangzhaiensis nothosp. diploid within Dryopteridaceae. Morphologically, exhibits similarities...
The Lingguizhugan decoction (LGZGD) is a promising traditional Chinese medicine for the treatment of gestational diabetes mellitus (GDM). However, its bioactive compounds and therapeutic mechanisms remain unknown. main chemical composition LGZGD was analyzed by high-performance liquid chromatography-mass spectrometry (HPLC-MS). Furthermore, underlying against GDM were elucidated through network pharmacology molecular docking. efficacy targets further confirmed via an in vitro model (high...
Ultrasound-assisted extraction (UAE), using petroleum ether as the solvent, was systematically applied to extract main macamides and macaenes from Maca hypocotyls. Extraction yield related with four variables, including ratio of solution solid, temperature, time, power. On basis response surface methodology (RSM), optimal conditions were determined be solid 10:1 (mL/g), temperature 40 °C, time 30 min, power 200 W. Based on method UAE, total contents ten two cultivated in twenty different...
Cyclotides are plant-derived macrocyclic peptides with potential applications in the pharmaceutical and agricultural industries. In addition to their presumed natural function as host-defence arising from insecticidal activity, other biological activities include antimicrobial, haemolytic, cytotoxic activities, but at present, only limited information is available on structural chemical features that important for these various activities. current study, we determined three-dimensional...
Two α-L-ribo-configured bicyclic nucleic acid modifications, represented by analogues 12 and 13, which are epimeric at C3' C5' have been synthesized using a carbohydrate-based approach to build the core structure. An intramolecular L-proline-mediated aldol reaction was employed generate cis-configured ring junction of analogue represents rare application this venerable organocatalytic carbohydrate system. In case where trans-ring desired, an intermolecular diastereoselective Grignard...
