Nutritional, Chemical, Antioxidant and Antibacterial Screening of Astragalus cicer L. and Astragalus glycyphyllos L. Different Morphological Parts. Foods 2025; 14:250. [PMID: 39856916 PMCID: PMC11764730 DOI: 10.3390/foods14020250] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2024] [Revised: 12/15/2024] [Accepted: 01/07/2025] [Indexed: 01/27/2025] Open
Abstract
The chemical composition and biological activity of A. glycyphylos and A. cicer are scarcely investigated. In this study, the nutritional and chemical profiles of A. cicer and A. glycyphyllos, considering their different morphological parts (leaves, fruits and roots), were assessed together with their antioxidant and antibacterial potential. Our results showed that carbohydrates are the major macronutrients in both Astragalus species (above 62 g/100 g dry weight-DW). High amounts of ash (above 4.6 g/100 g DW) and protein (above 13.0 g/100 g DW) were also identified, particularly in leaves and fruits of A. cicer and A. glycyphyllos. Moreover, A. cicer was richer in sugars than A. glycyphyllos, while roots of both Astragalus species were the richest of fatty acids. Ten phenolic compounds were identified, with gallic acid and quercetin being predominant, above 49.84 and 37.27 μg/g DW, respectively. The mineral analysis revealed zinc and iron as the major constituents. Regarding the plants' antioxidant and antibacterial activity, both Astragalus species had antioxidant potential, and their water extracts showed antibacterial activity against S. aureus and E. coli. Altogether, these results provide insight into the potential of A. glycyphyllos and A. cicer as a source of nutritional benefits and active phytochemicals for many people, and they can be applied in the food sector as foods and as promising sources of natural ingredients.

Changes in the rhizosphere and root-associated bacteria community of white Guinea yam ( Dioscorea rotundata Poir.) impacted by genotype and nitrogen fertilization. Heliyon 2024; 10:e33169. [PMID: 39021943 PMCID: PMC11252748 DOI: 10.1016/j.heliyon.2024.e33169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 06/11/2024] [Accepted: 06/14/2024] [Indexed: 07/20/2024] Open
Abstract
The bacterial diversity and composition of water yam (Dioscorea alata L. cv. A-19), which can grow without chemical fertilization, have recently been characterized with no significant differences compared with the use of chemical fertilization. However, the diversity and community structure of bacteria associated with the white Guinea yam (Dioscorea rotundata), the most cultivated and economically important yam in West Africa, have not yet been investigated. This study characterized the bacterial diversity and composition associated with bulk soil, rhizosphere, and plant roots in six white Guinea yam genotypes (S004, S020, S032, S042, S058, and S074) in field experiments in Ibadan, Nigeria under N-based chemical fertilizer application. The largest diversity of bacteria was found in the bulk soil, followed by the rhizosphere and roots. Based on the alpha diversity analysis, the bacterial diversity in both S020 and S042 increased with fertilizer application among the bulk soil samples. S058 grown under no-fertilizer conditions had the highest bacterial diversity among the rhizosphere samples. Beta diversity analysis highlighted the significant difference in the composition of bacteria associated with the genotypes and fertilizer treatments, and S032 had a unique bacterial composition compared to the other genotypes. The dominant phylum across all sample types was Proteobacteria. Actinobacteriota was the dominant phylum among bulk soil samples. At the genus level, Bacillus was the most abundant bacterial genus across both the control and treated samples. Pseudomonas was predominant across all rhizosphere samples. Chryseobacterium, Sphingobium, Delftia and Klebsiella associated with the rhizosphere were shown the altered relative abundance between the control and treated samples depending on genotypes. A genus related to symbiotic nitrogen-fixing bacteria, the Allorhizobium-Neorhizobium-Pararhizobium-Rhizobium clade, showed higher relative abundance among all root samples, indicating that it is a core bacterial genus. Furthermore, the field application of chemical fertilizer had a significant impact on the relative abundances of two genera related to symbiotic nitrogen-fixers, Allorhizobium-Neorhizobium-Pararhizobium-Rhizobium clade and Bradyrhizobium in the rhizosphere and root. These results suggest that N-based chemical fertilizers and plant genotypes would influence the compositional arrangement of associated bacterial communities, including symbiotic nitrogen-fixing bacteria.

Abstract
A novel bacterium, designated strain MMK2T, was isolated from a surface-sterilised root nodule of a Trifolium rubens plant growing in south-eastern Poland. Cells were Gram negative, non-spore forming and rod shaped. The strain had the highest 16S rRNA gene sequence similarity with P. endophytica (99.4%), P. leporis (99.4%) P. rwandensis (98.8%) and P. rodasii (98.45%). Phylogenomic analysis clearly showed that strain MMK2T and an additional strain, MMK3, should reside in the genus Pantoea and that they were most closely related to P. endophytica and P. leporis. Genome comparisons showed that the novel strain shared 82.96-93.50% average nucleotide identity and 26.2-53. 2% digital DNA:DNA hybridization with closely related species. Both strains produced siderophores and were able to solubilise phosphates. The MMK2T strain was also able to produce indole-3-acetic acid. The tested strains differed in their antimicrobial activity, but both were able to inhibit the growth of Sclerotinia sclerotiorum 10Ss01. Based on the results of the phenotypic, phylogenomic, genomic and chemotaxonomic analyses, strains MMK2T and MMK3 belong to a novel species in the genus Pantoea for which the name Pantoea trifolii sp. nov. is proposed with the type strain MMK2T (= DSM 115063T = LMG 33049T).

Abstract
This study was to explore the differences in the distribution and species diversity of bacteria between hepatocellular carcinoma (HCC) tissues and normal liver tissues. 28 HCC patients treated with surgery were selected as the research objects (HCC group), and 19 healthy volunteers
with normal physical examinations were included in the control group (Normal group). The tumor specimens were obtained by intraoperative and biopsy puncture, and a 16S ribosomal ribonucleic acid (rRNA) library was constructed. Based on the sequencing data obtained by the IlluminaHi Seq sequencing
platform, the differences of bacteria in the liver tissues of the HCC group and the Normal group were analyzed at the level of phyla, family, and genus. The Ace, Chao1, and Shannon of the two groups were compared. The results showed that IlluminaHi Seq sequencing obtained a total of 11,714,659
valid sequences, with an average of 131,625 sequences per sample. The proportions of Bacteroidetes, Firmicutes, and Proteobacteria in HCC group and Normal group were 48.75% versus 34.16%, 37.44% versus 18.02%, and 10.85% versus 39.26%, respectively. The Bacteroidaceae, Prevotellaceae, Lachnospiraceae,
and Ruminococcaceae accounted for 22.49%, 20.62%, 16.54%, and 19.93% in Normal group; while those in the HCC tissues accounted for 26.83%, 14.22%, 11.14%, and 13.18%, respectively. The dominant bacteria at the genus level in HCC group and Normal group were Bacteroides and Prevotella-9, with
the proportions of 24.19% versus 26.04% and 14.19% versus 8.44%, respectively. The difference in operational taxonomic unit (OTU) numbers of HCC and Normal group were compared and analyzed, which were 1,266 and 1,082, respectively, and the number of common OTU in the two tissues was 875. The
Ace in HCC tissue and normal liver tissue were 1063.8±66.79 and 1003.6±52.19, respectively. The Ace in HCC tissue was greater than that in normal liver tissue (P < 0.05). The Chao1 and Shannon in HCC tissue were 1022.9±67.74 and 5.4269±0.3608, respectively;
while those in normal liver tissue were 1003.6±66.79 and 5.2842±0.9714, respectively. The Chao1 and Shannon in HCC tissues were much higher than those in Normal group (P < 0.05). It showed that there was no difference in the types of bacterial species in HCC tissues,
but the proportions of their flora at the level of phyla, family, and genus changed greatly, which may be related to the occurrence of HCC. This study could provide a reference for the diagnosis and treatment of HCC.

Abstract
Fifty seven bacterial isolates from root nodules of two spontaneous legumes (Astragalus corrugatus and Hippocrepis areolata) growing in the arid areas of Tunisia were characterized by phenotypic features, 16S rDNA PCR-RFLP and 16S rRNA gene sequencing. Phenotypically, our results indicate that A. corrugatus and H. areolata isolates showed heterogenic responses to the different phenotypic features. All isolates were acid producers, fast growers and all of them used different compounds as sole carbon and nitrogen source. The majority of isolate grew at pHs between 6 and 9, at temperatures up to 40°C and tolerated 3% NaCl concentrations. Phylogenetically, the new isolates were affiliated to four genera Sinorhizobium, Rhizobium, Mesorhizobium and Agrobacterium. About 73% of the isolates were species within the genera Sinorhizobium and Rhizobium. The isolates which failed to nodulate their host plants of origin were associated to Agrobacterium genus (three isolates).

Mineral and Phytochemical Profiles and Antioxidant Activity of Herbal Material from Two Temperate Astragalus Species. BIOMED RESEARCH INTERNATIONAL 2018; 2018:6318630.

Abstract
Only a few species of the large Astragalus genus, widely used for medicinal purposes, have been thoroughly studied for phytochemical composition. The aim of our research was to investigate the rarely studied species A. glycyphyllos L. and A. cicer L. for the distribution of mineral elements and phytochemicals in whole plants at two growth stages and in morphological fractions. We also investigated the capacity of the plant extracts to scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals and to chelate ferrous ions. Chemical composition and antioxidant properties depended on species, maturity, and plant part. Herbal material of A. glycyphyllos was richer in Fe, total phenolics, and flavonoids, whereas extracts of A. cicer showed a higher antioxidant activity. Young plants had more isoflavones, showed greater quenching of DPPH radicals, and exhibited better mineral profiles than flowering plants. Among plant parts, leaves were the most valuable plant material according to most characteristics investigated. Isoflavone concentration in flowers was lower than in leaves and stems. None of the Astragalus samples contained detectable amounts of the alkaloid swainsonine. The study demonstrates the potential of plant material from two Astragalus species as a valuable source of iron, phenolic substances including isoflavones, free-radical scavengers, and Fe2+ chelators for pharmaceutical use.

Abstract
This is the first report describing isolates from root nodules of Ononis arvensis (field restharrow). The aim of this investigation was to describe the diversity, phylogeny, and plant growth promoting features of microsymbionts of O. arvensis, i.e., a legume plant growing in different places of the southern part of Poland. Twenty-nine bacterial isolates were characterized in terms of their phenotypic properties, genome fingerprinting, and comparative analysis of their 16S rRNA, nodC and acdS gene sequences. Based on the nodC and 16S rRNA gene phylogenies, the O. arvensis symbionts were grouped close to bacteria of the genera Rhizobium and Mesorhizobium, which formed monophyletic clusters. The acdS gene sequences of all the isolates tested exhibited the highest similarities to the corresponding gene sequences of genus Mesorhizobium strains. The presence of the acdS genes in the genomes of rhizobia specific for O. arvensis implies that these bacteria may promote the growth and development of their host plant in stress conditions. The isolated bacteria showed a high genomic diversity and, in the BOX-PCR reaction, all of them (except three) exhibited DNA fingerprints specific only for them. Our studies showed that restharrow isolates formed effective symbiotic interactions with their native host (O. arvensis) and Ononis spinosa but not with Trifolium repens and Medicago sativa belonging to the same tribe Trifolieae as Ononis species and not with Lotus corniculatus, representing the tribe Loteae.

Abstract
Rhizobia nodulating native Astragalus and Oxytropis spp. in Northern Europe are not well-studied. In this study, we isolated bacteria from nodules of four Astragalus spp. and two Oxytropis spp. from the arctic and subarctic regions of Sweden and Russia. The phylogenetic analyses were performed by using sequences of three housekeeping genes (16S rRNA, rpoB and recA) and two accessory genes (nodC and nifH). The results of our multilocus sequence analysis (MLSA) of the three housekeeping genes tree showed that all the 13 isolates belonged to the genus Mesorhizobium and were positioned in six clades. Our concatenated housekeeping gene tree also suggested that the isolates nodulating Astragalus inopinatus, Astragalus frigidus, Astragalus alpinus ssp. alpinus and Oxytropis revoluta might be designated as four new Mesorhizobium species. The 13 isolates were grouped in three clades in the nodC and nifH trees. 15N analysis suggested that the legumes in association with these isolates were actively fixing nitrogen.

Abstract
The plant growth-promoting rhizobacteria have developed many different (indirect and direct) mechanisms that have a positive effect on plant growth and development. Strains isolated from Astragaluscicer and Astragalusglycyphyllos root nodules were investigated for their plant growth-promoting properties such as production of indole-3-acetic acid (IAA) and siderophores, phosphate solubilization, ACC deaminase activity, and tolerance to heavy metals. IAA production and P-solubilization were frequent features in the analysed strains, while siderophores were not produced by any of them. In this work, we investigated the presence of the acdS genes and ACC deaminase activities in Astragalauscicer and A. glycyphyllos microsymbionts, classified within the genus Mesorhizobium. The results demonstrated that the acdS gene is widespread in the genome of Astragalus sp. microsymbionts; however, none of the tested strains showed ACC deaminase activity. The acdS gene sequence similarity of the analysed strains to each other was in the range from 84 to 99 %. On the phylogram of acdS gene sequences of milkvetch, the symbionts clustered tightly with the genus Mesorhizobium bacteria.

Genetic diversity and distribution of rhizobia associated with the medicinal legumes Astragalus spp. and Hedysarum polybotrys in agricultural soils. Syst Appl Microbiol 2016; 39:141-9. [PMID: 26915496 DOI: 10.1016/j.syapm.2016.01.004] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2015] [Revised: 01/28/2016] [Accepted: 01/29/2016] [Indexed: 10/22/2022]
Abstract
With the increasing cultivation of medicinal legumes in agricultural fields, the rhizobia associated with these plants are facing new stresses, mainly from fertilization and irrigation. In this study, investigations on the nodulation of three cultivated medicinal legumes, Astragalus mongholicus, Astragalus membranaceus and Hedysarum polybotrys were performed. Bacterial isolates from root nodules of these legumes were subjected to genetic diversity and multilocus sequence analyses. In addition, the distribution of nodule bacteria related to soil factors and host plants was studied. A total 367 bacterial isolates were obtained and 13 genospecies were identified. The predominant microsymbionts were identified as Mesorhizobium septentrionale, Mesorhizobium temperatum, Mesorhizobium tianshanense, Mesorhizobium ciceri and Mesorhizobium muleiense. M. septentrionale was found in most root nodules especially from legumes grown in the barren soils (with low available nitrogen and low organic carbon contents), while M. temperatum was predominant in nodules where the plants were grown in the nitrogen-rich fields. A. mongholicus tended to be associated with M. septentrionale, M. temperatum and M. ciceri in different soils, while A. membranaceus and H. polybotrys tended to be associated with M. tianshanense and M. septentrionale, respectively. This study showed that soil fertility may be the main determinant for the distribution of rhizobia associated with these cultured legume plants.

PLoS One 2015; 10:e0141504.

Abstract
The phylogeny of symbiotic genes of Astragalus glycyphyllos L. (liquorice milkvetch) nodule isolates was studied by comparative sequence analysis of nodA, nodC, nodH and nifH loci. In all these genes phylograms, liquorice milkvetch rhizobia (closely related to bacteria of three species, i.e. Mesorhizobium amorphae, Mesorhizobium septentrionale and Mesorhizobium ciceri) formed one clearly separate cluster suggesting the horizontal transfer of symbiotic genes from a single ancestor to the bacteria being studied. The high sequence similarity of the symbiotic genes of A. glycyphyllos rhizobia (99-100% in the case of nodAC and nifH genes, and 98-99% in the case of nodH one) points to the relatively recent (in evolutionary scale) lateral transfer of these genes. In the nodACH and nifH phylograms, A. glycyphyllos nodule isolates were grouped together with the genus Mesorhizobium species in one monophyletic clade, close to M. ciceri, Mesorhizobium opportunistum and Mesorhizobium australicum symbiovar biserrulae bacteria, which correlates with the close relationship of these rhizobia host plants. Plant tests revealed the narrow host range of A. glycyphyllos rhizobia. They formed effective symbiotic interactions with their native host (A. glycyphyllos) and Amorpha fruticosa but not with 11 other fabacean species. The nodules induced on A. glycyphyllos roots were indeterminate with apical, persistent meristem, an age gradient of nodule tissues and cortical vascular bundles. To reflect the symbiosis-adaptive phenotype of rhizobia, specific for A. glycyphyllos, we propose for these bacteria the new symbiovar "glycyphyllae", based on nodA and nodC genes sequences.

Insight into the genomic diversity and relationship of Astragalus glycyphyllos symbionts by RAPD, ERIC-PCR, and AFLP fingerprinting. J Appl Genet 2015; 56:551-554.

Abstract
We assessed the genomic diversity and genomic relationship of 28 Astragalus glycyphyllos symbionts by three methodologies based on PCR reaction, i.e., RAPD, ERIC-PCR, and AFLP. The AFLP method with one PstI restriction enzyme and selective PstI-GC primer pair had a comparable discriminatory power as ERIC-PCR oneand these fingerprinting techniques distinguished among the studied 28 A. glycyphyllos symbionts 18 and 17 genomotypes, respectively. RAPD method was less discriminatory in the genomotyping of rhizobia analyzed and it efficiently resolved nine genomotypes. The cluster analysis of RAPD, ERIC-PCR, and AFLP profiles resulted in a generally similar grouping of the test strains on generated dendrograms supporting a great potential of these DNA fingerprinting techniques for study of genomic polymorphism and evolutionary relationship of A. glycyphyllos nodulators. The RAPD, ERIC-PCR, and AFLP pattern similarity coefficients between A. glycyphyllos symbionts studied was in the ranges 8–100, 18–100, and 23-100 %, respectively.
