Beta vulgaris L. is a root vegetable that is consumed mainly as a food additive. This study aimed to describe the protective effect of B. vulgaris on Fe2+-mediated oxidative liver damage through in vitro, ex vivo, and in silico studies to establish a strong rationale for its protective effect. To induce oxidative damage, we incubated the livers of healthy male rats with 0.1 mM FeSO4 to induce oxidative injury and coincubated them with an aqueous extract of B. vulgaris root (BVFE) (15–240 µg/mL). Induction of liver damage significantly (p <.05) decreased the levels of GSH, SOD, CAT, and ENTPDase activities, with a corresponding increase in MDA and NO levels and Na+/K+ ATPase, G6 Pase, and F-1,6-BPase enzyme activities. BVFE treatment (p <.05) reduced these levels and activities to almost normal levels, with the most prominent effects observed at 240 µg/mL BVFE. An HPLC investigation revealed sixteen compounds in BVFE, with quercetin being the most abundant. Chlorogenic acid and iso-orientation showed the highest binding affinities for G6 Pase and Na+/K + ATPase, respectively. These findings suggest that B. vulgaris can protect against Fe2+-mediated liver damage by suppressing oxidative stress and cholinergic and purinergic activities while regulating gluconeogenesis. Overall, the hepatoprotective activity of this extract might be driven by the synergistic effect of the identified compounds and their probable interactions with target proteins.

Summary: Eukaryotic translation initiation factors (eIFs) are important for mRNA translation but also pivotal for plant‐virus interaction. Most of these plant‐virus interactions were found between plant eIFs and the viral protein genome‐linked (VPg) of potyviruses. In case of lost interaction due to mutation or deletion of eIFs, the viral translation and subsequent replication within its host is negatively affected, resulting in a recessive resistance. Here we report the identification of the Beta vulgaris Bv‐eIF(iso)4E as a susceptibility factor towards the VPg‐carrying beet chlorosis virus (genus Polerovirus). Using yeast two‐hybrid and bimolecular fluorescence complementation assays, the physical interaction between Bv‐eIF(iso)4E and the putative BChV‐VPg was detected, while the VPg of the closely related beet mild yellowing virus (BMYV) was found to interact with the two isoforms Bv‐eIF4E and Bv‐eIF(iso)4E. These VPg‐eIF interactions within the polerovirus‐beet pathosystem were demonstrated to be highly specific, as single mutations within the predicted cap‐binding pocket of Bv‐eIF(iso)4E resulted in a loss of interaction. To investigate the suitability of eIFs as a resistance resource against beet infecting poleroviruses, B. vulgaris plants were genome edited by CRISPR/Cas9 resulting in knockouts of different eIFs. A simultaneous knockout of the identified BMYV‐interaction partners Bv‐eIF4E and Bv‐eIF(iso)4E was not achieved, but Bv‐eIF(iso)4EKO plants showed a significantly lowered BChV accumulation and decrease in infection rate from 100% to 28.86%, while no influence on BMYV accumulation was observed. Still, these observations support that eIFs are promising candidate genes for polerovirus resistance breeding in sugar beet. [ABSTRACT FROM AUTHOR]

Aircraft designers have been looking for light-weight and robustness from natural fibers since the earlier times. To address this concern, scientists are currently working together on the bamboo long fiber reinforced bio-based matrix composite (BAMCO) project. This study focused on Bambusa vulgaris , a dominant bamboo species in Cameroon, to evaluate its potential for use in airline industries. The aim of the study is to determine the age at which Bambusa vulgaris fibers have the best mechanical and thermal properties for the manufacture of hybrid composites applied to aeronautics and aerospace. B. vulgaris plants aged 1–3 years, 4–5 years and 7 years were characterized, by submitting specimens to several tests: 1) density measurement, 2) tensile tests, 3) scanning electron microscopy (SEM), 4) Fourier-transform infrared spectroscopy (FTIR), 5) thermal conductivity, 6) thermogravimetric analysis (TGA), 7) specific heat capacity measurement, 8) dynamic mechanical analysis (DMA), and 9) ILSS test. A comparative study of the properties of other natural fiber tested in the aeronautic and aerospace industries revealed that, 7-year-old B. vulgaris has good properties for the airline industry. This study provides evidence that a 7-year-old B. vulgaris plant has a potentially important role in aeronautical and aerospace composite materials. • B. vulgaris aged 1–3 years, 4–5 years and 7 years were characterized. • From results 7-year-old B. vulgaris has the potential for aeronautic applications. • A hybrid composite made of B. vulgaris fiber is propose.

Plants have evolved a variety of defences to reduce losses to herbivores and pathogens. The benefits of these may, however, be modified by resistance evolution in antagonists, changes in antagonist fauna, context-dependent "costs of defence", and by interactions between antagonists. In Barbarea vulgaris (Brassicaceae), the so-called "G-type" produces triterpenoid saponins that deter important specialist insect herbivores, whereas the "P-type" produces other saponins and are not insect-resistant. In contrast, P-type plants are predominantly resistant to the biotroph pathogen Albugo sp., causing white blister rust, whilst most G-type plants are susceptible. In a field experiment with F3 hybrids between G and P-plants, we tested whether the two resistances are functionally coupled, leads to less disease and herbivory and to better plant performance, and whether insect herbivores and the pathogen interact in their effects on plant performance. The Albugo and insect resistances varied continuously between the F3 plants and mapped to different linkage groups, indicating independent mechanisms and evolution. Plants with high Albugo resistance produced more biomass and survived better than more susceptible plants. Albugo DNA was detected in surface-sterilized green siliques, indicating systemic and sometimes non-symptomatic infection. Plants with high insect resistance were slightly less damaged by herbivores, but did not grow or survive better than more susceptible plants. Interactions between Albugo and insect herbivores did not affect plant performance. In contrast to the Albugo resistance, which clearly benefited the plants, our results show that the saponin-based insect resistance did convey any benefit under the given conditions despite its deterrent effects in controlled experiments.

One of the main drawbacks which limit the utilisation of bamboos is its high moisture intake. To prevent excessive dimensional changes and improve moisture properties of bamboo, Bambusa vulgaris was chemically treated with acetic-anhydride without co-solvent. Weight gain (WPG), Bulking coefficient (BC), Rate of reaction (RR), Volumetric Swelling (VS) and Anti-swelling Efficiency (ASE) as well as changes in VS and ASE upon long term water soaking and weight loss to leaching (WL) were determined to evaluate the influence of acetylation on the moisture properties. The results indicated no significant effect of reaction temperature and time on the WPG, BC, VS and ASE of the acetylated bamboo while reaction time had significant influence on RR and WL. None of the acetylated bamboo samples had more than 3.67% WPG and 54.69% ASE. The maximum values of ASE of acetylated bamboo was 54.69% at 2.79 WPG, 100oC and 90 minutes while the lowest 13.08% was recorded at 2.89% WPG, 140oC and 30 mins reaction times. Reaction temperature had no influence on the initial and final volumetric swelling and final anti-swelling efficiency of the modified bamboo samples but reaction time had significant effect on initial ASE. Volumetric swelling of modified and unmodified samples increased from 8.47 to 18.58% and from 9.42% to 43.22% respectively within 7 days water soak period. Acetic anhydride form chemical bonds that were stable to solvent extraction in B. vulgaris. Acetylating at 120°C for 30 and 60 minutes is suitable for B. vulgaris to positively influence its sorption properties. [ABSTRACT FROM AUTHOR]

Bamboo possesses many unique physiological characteristics, but the molecular understanding of many of these processes remains poorly understood till to date. One major reason is unavailability of sufficient sequence and expression data. Selection of suitable reference genes is pivotal to initiate any gene expression analyses. Although, suitable reference genes have been identified in the temperate bamboo Phyllostachys edulis, it has not been done for tropical bamboo. In this study, expression stability of 10 candidate reference genes were investigated in 4 widely grown tropical bamboo species (Bambusa tulda, B. balcooa, B. bambos, and B. vulgaris), different organs (young leaves from flowering and non flowering culms, flag leaf (leaf just below the mature inflorescence), possible flag leaf (leaf covering the immature inflorescence), culm sheath, internode, root, rhizome, and inflorescence bud), different parts (basal, middle, and tip regions of leaf; internodes located in the basal, middle, and tip region of the branch, and developmental stages early, middle, and late inflorescence buds) by using 3 reliable computational tools (geNorm, NormFinder, and RefFinder). A universal single reference gene for normalization of gene expression data was not identified. However, the eukaryotic initiation factor 4α (eIF4α), clathirin adaptor complexes medium subunit (CAC), and nucleotide tract-binding protein (NTB) were found stable in the selected organs across different bamboo species. On the other hand, eIF4α ranked top when different organs and peptidyl prolyl cis-trans isomerase/cyclophilin (CYP), eukaryotic elongation factor 1α (eEF1α) and ubiquitin 5 (UBQ5) ranked top when different developmental stages of B. tulda were analyzed. Taken together, this study not only identifies reference gene/s that are stable across species, organs, and developmental stages of bamboo, but it also assesses the impacts of major contributing factors regulating expression stability of the reference genes.

Objective: Medicinal plants have attracted global attention due to their safety as well as their considerable antioxidant content that helps to prevent or ameliorate various disorders including memory impairments. This study was conducted to investigate the effect of beet root (Beta vulgaris) leaf extract on scopolamine-induced spatial memory impairments in male Wistar rats. Materials and Methods: Male Wistar rats were randomly divided into 5 groups (n=10): Control (C), scopolamine 1 mg/kg/day (S), scopolamine+50 mg/kg B. vulgaris leaf extract (S+B 50), scopolamine+100 mg/kg B. vulgaris leaf extract (S+B 100) and scopolamine+200 mg/kg B. vulgaris leaf extract (S+B 200). Morris water maze task was used to assess spatial memory. Serum antioxidant capacity and malondialdehyde (MDA) level were also measured. Results: Group S spent significantly less time in the target quadrant compared to the control group, and the administration of B. vulgaris leaf extract (100 and 200 mg/kg) significantly increased this time (p

The present research was done to study the ability of cyanobacterial species for removing heavy metals from sewage. As well, to estimate the growth and some metabolites ofBeta vulgarisirrigated with sewage treated by cyanobacterial species. The best removal results were obtained byAnabaena oryzaecompared to the other studied cyanobacteria. WhereasA. oryzaeshowed high removal efficiency for cadmium (Cd2+) followed by lead (Pb2+), zinc (Zn2+), iron (Fe2+), copper (Cu2+) and manganese (Mn2+) (88.5, 83.1, 68.8, 62.0, 55.2 and 42.4%, respectively). Irrigation of plants by untreated or treated sewage generally caused stimulation in the total proteins, proline, carbohydrates and ascorbic acid.B. vulgarisgrown in soil irrigated with untreated sewage showed maximum catalase, peroxidase activity, hydrogen peroxide (H2O2) and lipid peroxidation compared to the other treatments. The heavy metals availability was relatively low in the plant irrigated with treated sewage by cyanobacterial species, so the antioxidants requirement was low and hence the induction of antioxidants was lower compared to the plant irrigated with untreated sewage.

Morris water maze task was used to assess spatial memory. Serum antioxidant capacity and malondialdehyde (MDA) level were also measured. Results: Group S spent significantly less time in the target quadrant compared to the control group, and the administration of B. vulgaris leaf extract (100 and 200 mg/kg) significantly increased this time (p<0.05). Scopolamine decreased serum antioxidant capacity and increased serum MDA level yet insignificantly. B. vulgaris extract (200 mg/kg) significantly increased the antioxidant capacity and decreased serum MDA level in scopolamine-treated rats (p<0.05). Conclusion: Our results suggested that B. vulgaris leaf extract could ameliorate the memory impairments and exhibited protective effects against scopolamine-induced oxidation. Further investigation is needed to isolate specific antioxidant compounds from B. vulgaris leaf extract with protective effect against brain and memory impairments. [ABSTRACT FROM AUTHOR]

Employing of the composite electrospun scaffold containing herbal extract in conjugation with co-culturing of cells can open up new window to the design of efficient biomaterials for skin tissue regeneration. Here, we introduce the synergistic effect of composite electrospun nanofibrous scaffold of nylon66 loaded with Beta vulgaris ( B. vulgaris ) (extract of beet roots, a plants whose widely used in Iranian folk medicine as wound healing medicine) and co-culture of mesenchymal stem-cells (MSCs)-human keratinocyte (H-keratino) differentiation towards epithelial lineage. In vitro biocompatibility was examined through MTT assay and epithelial differentiation checked by real-time PCR and immunocytochemistry (ICC) assay after co-culturing of MSCs and H-keratino on proposed scaffold. Significant enhancement in cell proliferation was detected after cell culturing on the composite type of electrospun scaffold containing B. vulgaris . Moreover, after 14 days of co-culturing process, gene expression results revealed that both composite and non-composite nylon66 electrospun scaffold promote epithelial differentiation compared to mono-cell culturing of H-keratino in terms of several markers as Cytokeratin 10, Cytokeratin 14 and Involucrin and ICC of some dermal proteins like Cytokeratin 14 and Loricrin. To the best of our knowledge, findings of this study will introduce new way for the generation of novel biomaterials for the development of current skin tissue engineering. [ABSTRACT FROM AUTHOR]

The obtaining of good quality plants for mass production of bamboo is an important factor due to the conventional methods of spreading have been little studied and limited their spreading. The present paper was carried out under green house conditions, with the purpose of evaluating the effect on spreading method factors, species of bamboo (CH, V y SN), (Ga, Bo y Bv) and substrate (ATC, TCE y SIC) about the surviving (SPV), number of shoots (NH), number of roots (NR), length of roots (LR), number of leaves by seedlings (NHA), height (AL) and diameter of stalk (DI) of the first shoot of plants of de bamboo in pots of black polyethylene The treatments were random established with three fold repetition The results were evaluated at the end of the experiment.( DDT). The method by chusquin is better. than varetas and nodal segments for the variants under study. The vareta and nodal segment offer less surviving and less number of shoots. Meantime the Guadua angustifolia and Bambusa vulgaris are the best species in relation to Bambusa oldhamii for bamboo spreading , regardless the substrate used.

EcoRI monomers of a highly repetitive DNA family of Beta vulgaris have been cloned. Sequence analysis revealed that the repeat length varies between 157-160 bp. The percentage of AT-residues is 62% on average. The basic repeat does not show significant homology to the BamHI sequence family of B. vulgaris that was analyzed by us earlier. Both the EcoRI and BamHI sequences are investigated and compared to each other with respect to their genomic organization in the genus Beta. Both repeats were found to be tandemly arranged in the genome of B. vulgaris in a satellite-like manner. The EcoRI satellite DNA is present in three sections ( Beta, Corollinae and Nanae) of the genus, whereas the BamHI satellite DNA exists only in the section Beta. The distribution of the EcoRI and BamHI satellite families in the genus is discussed with respect to their evolution. [ABSTRACT FROM AUTHOR]
