“…Previous phylogenetic studies using several gene regions revealed three well-supported clades in the genus Elaeagnus L. ( Liu et al, 2019 ; Alexandrov and Karlov, 2021 ). Similarly, our results indicated that both MP and ML trees showed three or four well-supported clades in the genus Elaeagnus L. For the first time, we used the matK sequence of the DNA marker region of the chloroplast genome, and the obtained molecular phylogeny was concordant with the morphological taxonomy.…”

“…Nevertheless, it is interesting that the selection and breeding based on the excellent genetic material of E. conferta have been developed for nearly 20 years in mainland China ( Gill and Gupta, 2018 ; Liu et al, 2019 ). E. conferta has an absolute advantage in fruit size, but distribution is limited in China’s low latitude subtropical regions, such as Yunnan and Guangxi Provinces.…”

“…Besides, the strict consensus trees based on cpDNA and morphological characters of the Elaeagnaceae showed that the genera Elaeagnus and Hippophae are are similar in chloroplast DNA sequence ( Zhao et al, 2020 ). Phylogenetic trees constructed by the maximum likelihood (ML) method based on complete chloroplast or plastid genomes also showed that the genus Elaeagnus has a close relationship with the genus Hippophae ( Choi et al, 2015 ; Liu et al, 2019 ; Cheng et al, 2020 ; Kim et al, 2020 ). At present, more phylogenetic and molecular clock analysis of Chinese Elaeagnus using DNA marker regions in the chloroplast genome, such as matK, rbcL, trnH-psbA, and trnL-F, has not been reported yet.…”

Elaeagnus L. is found in wild or grown as ornamental plants and is increasingly regarded as underutilized berry shrubs by breeders. This genus has cosmopolitan distribution with various species widely distributed in China, Europe, the United States, and Canada. Interspecific hybrids, which have been reported several times, have attracted intense interest from plant breeders attempting to develop a fruit crop of Elaeagnus. Orthogonal projections to latent structures discriminant analysis (OPLS-DA) is a powerful statistical modeling tool that provides insights into separations between experimental groups. In this study, the molecular phylogeny of Elaeagnus species was first discussed using the ITS and matK sequences for guiding the construction of a genetic basis pool. A morphological OPLS-DA clustering model based on the genetic divergence was also constructed for the first time, which effectively realized the morphological grouping of Chinese Elaeagnus species. The results showed that a total of 10 wild species widely distributed in China have the potential to develop fruit crops. Particularly, Elaeagnus conferta has the potential to provide a founder species with a large fruit size, while Elaeagnus Gonyanthes has the potential to provide important genetic resources with long pedicel. Elaeagnus lanceolata and Elaeagnus delavayi could be used to domesticate hybrids without spines, and the other five climbing shrubs could be used to develop high-yield crown-type commercial cultivars for automated field management. The top five contributing morphological traits affecting the current clustering model were V9 (flower color), V1 (flowering), V5 (evergreen or deciduous), V3 (leaf size), and V2 (fruiting). Furthermore, the grouping analysis indicated that the V9 was the most important factor affecting morphological clustering. Thereafter, the temporally calibrated phylogeny inferred from the matK sequence was used to reconstruct the origin and evolution of the genus Elaeagnus, and the results inferred an interesting geographic distribution pattern and potential cross-species interactions of Elaeagnus species at low latitudes in China. Our study also highlighted dispersal pattern investigation and genetic background analysis to improve future practices and policies related to species introduction of genetic basis pool.

“…The complete genome of E. angustifolia, as well as the E. macrophylla and E. conferta Roxb. chloroplast genomes, has been recently sequenced [5][6][7]. Furthermore, several attempts have been made to identify species in the Elaeagnus by using DNA barcoding when determining phylogenetic relationships and describing new species [8][9][10][11].…”

The Elaeagnus L. species are trees and bushes that mainly grow in temperate zones of Western Europe; Minor, Central, and Southeast Asia; the Far East; and North America. Some species are used as fruit or ornamental plants and have economic value. Problems with the identification of species in the Elaeagnus genus by molecular genetical methods arise in the study of populations, systematics, breeding, and other areas of plant science and practice. Recently, the polymorphism of 5S ribosomal DNA non-transcribed spacers (5S rDNA NTSs) in Elaeagnaceae Adans. has been described. The results were used in our study as a basis for development of new species-specific molecular markers for some members of the Elaeagnus genus. The author’s method was applied for finding regions that were potentially applicable for species-specific primer design. As a result, some species-specific molecular markers were developed for Elaeagnus angustifolia L., E. commutata Bernh., E. pungens Thunb., and E. multiflora Thunb. These markers were tested in a range of samples and showed the presence of amplified fragments in lanes of the marked species only. Samples of other species showed no amplifications. Thus, the developed markers may be useful for the species identification of the studied Elaeagnus plants in botanical, dendrological, and genetic research (especially in a leafless period of year), as well as in breeding and hybridization experiments.

“…Moreover it is reported that silver nano particles of leaf extract of E. conferta has been prepared and has wide application in field of pharmacology and industries (Gowtham Prasanth E, 2017;Phanjom et al, 2012). In traditional herbal medicine, the fruit, leaves and roots have been explored for the ailment of multiple diseases such as diabetes, ulcer, pain, rheumatism, diarrhea, inflammation and pulmonary disorders (Binu, 2011;Deshmukh and Waghmode, 2011;Gill and Gupta, 2018;Jin et al, 1999;Liu et al, 2019;Patil et al, 2012;Raghavendra et al, 2015;Rana and Samant, 2011). Fruits, either raw or in the form of juice, syrup, pickle, jelly etc, have been reported to be used as food supplement and is free from any side effects (Deshmukh and Waghmode, 2011).…”

Elaeagnus conferta Roxb. (Elaeaganaceae), is being used in traditional herbal medicines; as the fruits, leaves and roots of this plant have been explored for the treatment of different diseases such as diabetes, ulcer, pain, rheumatism, diarrhea, inflammation and pulmonary disorders and also possess high nutritional value. Various extracts i.e. methanol, chloroform and acetone of E. conferta seeds were prepared by cold maceration and subjected to qualitative phytochemical screening (flavonoids, alkaloids, terpenoids, saponins, tannins, steroids, quinons, proteins, cardiac glycosides, fatty acid, carbohydrates and proteins) using standard procedures. All the extracts were further screened for antibacterial activity by disc diffusion method. The three different extracts of seeds of E. conferta were found to contain various secondary metabolites like fatty acids and flavonoids and exhibited moderate to significant antibacterial activity against both Gram-positive and Gram-negative bacteria. The potency of methanolic extract at conc. i.e.100 µg/ml was found to be > 19 mm in all the strains of bacteria (Streptococcus pyogenes, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli) which is comparable to standard drug ciprofloxacin. The various extracts of E. conferta exhibited variable antimicrobial activity, hence may be a natural potentially effective antimicrobial agent. Therefore, the above findings are important to strive medicinal role of E. conferta in treatment of various diseases including microbial infection.
