The sole Frankia species with a validly published name, the type species F. alni, was described by Woronin (1886) as present in the root of alder. Until now no type strain has been designated for F. alni, even though the absence of a type strain has seriously inhibited the application of modern taxonomic methods to the genus Frankia. Thus, we propose that strain ACN14aT be recognized as the type strain of this species. We compare ACN14aT to two strains, CcI3T and BMG5.12T, isolated from Casuarina and Elaeagnus, respectively, based on chemotaxonomy, phenotype microarray data and molecular data retrieved from genome sequences...

Targeted Illumina sequencing of nitrogenase reductase (nifH) gene fragments and analyses of pair-end reads through a modified QIIME pipeline were used to assess the diversity of the actinomyceteous genus Frankia in three soils. Soils were vegetated with host or non-host plants, and included locations in Illinois (ABA, host), Colorado (CoMt, non-host), and Wisconsin (FMWI, non-host). After filtering, seven unique sequences were recovered for soil ABA, six for CoMt, and four sequences for FMWI. These sequences were included in a Bayesian topology anchored by published sequence data from pure cultures of Frankia...

In this research, extraction optimization, preliminary characterization and immunological activities in vitro of polysaccharides from Elaeagnus angustifolia L. pulp were investigated. A response surface methodology (RSM) with a Box-Behnken design (BBD) was used to optimize the extraction process. The maximum EAP yield was 9.82±0.38%, which is in good agreement with the predicted value (9.93±0.24%). Two homogeneous polysaccharides, EAP-1a and EAP-1b with molecular weights of 8.70kDa and 4.39kDa respectively, were prepared by DEAE-52 cellulose and Sephadex G-100 columns and characterized by HPLC, HPGPC, and FT-IR...

In the present study, zinc oxide nanoparticles (ZnO NPs) were rapidly synthesized at room temperature by treating zinc acetate dihydrate with the flower extract of Elaeagnus angustifolia (Russian olive). The formation of ZnO NPs was primarily confirmed by UV-visible absorption spectrum in the range of 250-700nm. XRD analysis and DLS particle size analyzer revealed the size of ZnO NPs. The FTIR spectrum revealed the presence of phytochemicals in the flower extract mediated ZnO NPs. Moreover, the morphology of the ZnO NPs was determined using SEM...

Osteoarthritis (OA) is one of the most common musculoskeletal disorders all over the world. Available anti-arthritic medications have only partial efficacy and their long-term use is associated with adverse events. Elaeagnus Angustifolia (EA) is a medicinal plant with analgesic and anti-inflammatory properties. The present study evaluated the impact of two doses of EA extract compared with ibuprofen on the severity of disease in patients with knee OA. This study was designed as a randomized, double blind, active-controlled and parallel group trial...

(EA) whole fruit and medulla powders on anthropometric indices, serum lipid profile, and atherogenic indices in females with knee osteoarthritis (OA) was investigated. Ninety females with mild to moderate knee osteoarthritis were randomly assigned to one of three groups-medulla powder, whole fruit powder, or placebo. The subjects received 15 g/day of medulla powder of EA, whole fruit powder of EA, or placebo...

The physicochemical properties, fatty acid profiles, content of tocopherol and sterol of the oils extracted from the nuts of Elaeagnus mollis Diels grown in different regions of China were studied in this work. The results indicated that the Elaeagnus mollis Diels nut oils contained about 0.2% sterols and the tocopherol contents were in the range of 119.6-128.6mg/100g. The nut oils were all rich in unsaturated fatty acids, especially oleic acid and linoleic acid. Furthermore, the main triacylglycerols species of the nut oils were all dilinoleoyl-monoolein (LOL), dioleoyl-monolinoleoyl (OLO) and trilinoleate (LLL)...

Quantitative PCR (qPCR) was used to follow population dynamics of indigenous Frankia populations in bulk soil, in leaf-litter-amended soil and in the rhizosphere of Alnus glutinosa or Casuarina equisetifolia at 2 matric potentials representing dry and wet conditions in soil microcosms. Analyses revealed between 10- and 100-fold increases of Frankia populations within the incubation period of 12 weeks independent of treatment. Numbers were generally higher under dry conditions and in the rhizosphere, with that of C...

Dissatisfaction from sexual relationships can result in deprivation as well as problems, such as depression, anxiety, and destruction of family's mental health. One hundred twenty-five women (18 to 40 years) who suffered from hypoactive sexual desire disorder were divided into Elaeagnus angustifolia flower (4.5 g g daily for 35 days), sildenafil citrate tablet (50 mg for 4 weeks), and control groups. The study data were collected using the Female Sexual Function Index and Spielberger's questionnaire and measurement of thyroid-stimulating hormone and prolactin hormone...

OBJECTIVE: To study and identify the three species of dry medicinal plant leaves trom Elaeagnus genus (E. pungens, E. lanceolata and E. henryi) by Infrared Spectroscopy(IR). METHODS: Fourier transform infrared spectroscopy and second derivative infrared spectroscopy were used to study and compare the characteristics of leaves of three Elaeagnus medicinal plants. RESULTS: The IR spectra and second derivative infrared spectra of the three Elaeagnus plants leaves were similar on the whole, the intensity or ratio of intensity of some absorption peaks still had certain distinctions, and the differences of the second derivative infrared spectra were more obvious...

Quantitative polymerase chain reaction (qPCR) was used to assess the abundance and relative distribution of host infection groups of the root-nodule forming, nitrogen-fixing actinomycete Frankia in four soils with similar physicochemical characteristics, two of which were vegetated with a host plant, Alnus glutinosa, and two with a non-host plant, Betula nigra. Analyses of DAPI-stained cells at three locations, i.e., at a distance of less than 1 m (near stem), 2.5 m (middle crown), and 3-5 m (crown edge) from the stems of both tree species revealed no statistically significant differences in abundance...

Elaeagnus mollis Diels is a group of shrubs and dwarf trees endemic to China and are endangered plants. However, the reason why these plants are endangered remains controversial. The current study aimed to explore the endangered status of E. mollis from a genetic perspective and to propose conservation strategies for this species. Using 16 polymorphic allozyme loci, the population genetic structure was investigated for three populations representing the taxa and variants. The variants exhibited relatively high levels of genetic variation compared to other woody shrubs with similar geographic distributions...

BACKGROUND: Exotic invasive plants alter the structure and function of native ecosystems and may influence the distribution and abundance of arthropod disease vectors by modifying habitat quality. This study investigated how invasive plants alter the ecology of Culex pipiens, an important vector of West Nile virus (WNV) in northeastern and midwestern regions of the United States. METHODS: Field and laboratory experiments were conducted to test the hypothesis that three native leaf species (Rubus allegheniensis, blackberry; Sambucus canadensis, elderberry; and Amelanchier laevis, serviceberry), and three exotic invasive leaf species (Lonicera maackii, Amur honeysuckle; Elaeagnus umbellata, autumn olive; and Rosa multiflora, multiflora rose) alter Cx...

The bark and fruit extracts of Elaeagnus umbellata have been investigated for their antibacterial, anti-fungal, insecticidal and phytotoxic activities. The petroleum ether extracts of the plant showed significant activity against E. faecalis. The activity of dichloromethane extract was also determined significant against S. aureus. The chloroform extract indicated low activity against E. coli, K. pneumoniae, B. subtilis and S. flexenari. The ethyl acetate fraction demonstrated significant activity against K...
