Abstract
This study aimed to produce and characterize a novel gluten-free cupcake for celiac and diabetes people. For this purpose, wheat flour and sugar in the cupcake formulation were fully replaced with soy flour and monk fruit. Also, samples containing wheat flour with sugar and monk fruit were prepared for comparison. The gluten-free cupcake without sucrose had a less specific volume and porosity index. To improve these properties, Cydonia oblonga (Cydonia Vulgaris) and Plantago ovata (Plantago genus) were used individually and in combination at concentrations of 1 and 2%. The cake containing no gum was made as a control as well. It was observed that addition of gums had positive effects on the specific volume, porosity index, and weight loss of cakes, but their incorporation increased their hardness. Based on the results, the fabrication of a novel and successful gluten-free cupcake replaced with soy flour, monk fruit, and gum is possible.

Abstract
BACKGROUND Selenium (Se) is an essential micronutrient for humans, but its deficiency as well as toxicity affects large number of people worldwide. Plantago ovata, a commercially important medicinal plant, is mainly cultivated in western regions of India, where elevated levels of Se have been found in soil. Thus, we evaluated the potential of Se biofortification in P. ovata via phytoremediation and its effect on the bioactive composition. RESULTS The results showed a significant alteration in various morphological and physiological parameters in a dose-dependent manner. The 10 µM Se dose improved seedling height, biomass and total chlorophyll content. There was a gradual increase in total Se content, with highest accumulation of 457.65 µg/g FW at 500 µM Se treatment. Se positively affected the antioxidative metabolism which was measured from the change in total antioxidant capacity, radical scavenging activity and Metallothionein 2 expression. Increasing levels of Se also affected the PAL activity, total polyphenol and flavonoid content. Caffeic acid, Coumaric acid and Rutin were found to be the most abundant phenolic compounds. CONCLUSIONS Low levels of selenium (below 50 µM) can successfully improve Se accumulation and elicit production of various polyphenols without hampering plant growth. Thus, Se fortification of P. ovata seedlings via phytoremediation appears to be a feasible and efficient way to enhance its nutraceutical value in dietary products.

Abstract
The aim of the study was to characterize raw aqueous extracts from Plantago ovata husk in terms of molecular chain mass, osmotic, hydrodynamic, and rheological properties. The raw extracts used in this study have not been yet investigated in the indicated research area. Determination of the molecular weight of the chains present in the extract was performed by gel permeation chromatography (GPC). Osmotic properties were characterized using membrane osmometry. Rheological properties were investigated via classical rotational rheology with normal force measurements, as well as less common but equally important measurements of extensional viscosity. Two types of chains with an average molecular mass of 200 and 1780 kDa were found. The values of the first virial coefficient (B2) indicate the predominance of biopolymer-biopolymer interactions. The hydrodynamic radius established at 25 and 30 °C was 74 and 67 nm, respectively, and lower than at 40 °C (>600 nm). The first critical concentration was determined: c*=0.11 g·dL-1. The dominance of negative normal force values resulting from the formation of a pseudo-gel structure of the heteroxylates was demonstrated. Extensional viscosity measurement results revealed that the studied extracts cannot be treated as simple shear-thinning fluids, as indicated by shear flow, but should be considered as viscoelastic fluids.

Abstract
Background The present study aimed at investigating the topical effect of the combination of Plantago ovata and vinegar on the improvement of rural cutaneous leishmaniasis lesions. Materials and Methods The present randomized double-blind controlled clinical trial was performed on 42 patients with rural skin leishmaniasis. In the case group, in addition to injecting glucantime into the lesion according to the latest national instructions, a combination of P. ovata and vinegar was applied topically twice a day for 8 weeks. In the control group, only glucantime injection into the lesion was performed for 8 weeks according to the latest national guidelines. At the end of the 1st, 2nd, 3rd, 4th, 8th, and 12th weeks after the intervention, the lesion area and improvement were evaluated and recorded. Results The results of the present study indicated the lesion area in the case group with the mean of 0.35 ± 0.39 cm and 0.18 ± 0.27 cm in the 8th and 12th weeks, respectively was significantly less than that of the control group with the mean of 0.64 ± 0.78 cm and 0.56 ± 0.44, respectively (P < 0.05). Twelve weeks after the intervention, 84.1% of the lesions in the case group and 65.9% of the lesions in the control group were completely improved (P < 0.05). Conclusion According to the results of the present study, the improvement of leishmaniasis lesion with the topical application of the combination of P. ovata and vinegar was significantly more than that of the control group in the 8th and 12th weeks after the intervention.

Abstract
Plantagos are important economical and medicinal plants that possess several bioactive secondary metabolites, such as phenolics, iridoids, triterpenes, and alkaloids. Triterpenoids are the ubiquitous and dynamic secondary metabolites that are deployed by plants for chemical interactions and protection under biotic/abiotic stress. Plantago ovata, a cultivated species, is the source of psyllium, while Plantago major, a wild species, has significant therapeutic potential. Wild species are considered more tolerant to stressful conditions in comparison to their cultivated allies. In view of this, the present study aimed to decipher the terpenoid biosynthetic pathway operative in P. ovata and P. major using a comparative transcriptomics approach. Majority of terpenoid biosynthetic genes were observed as upregulated in P. major including rate limiting genes of MVA (HMGR) and MEP (DXR) pathways and genes (α-AS, BAS, SM, and CYP716) involved in ursolic acid biosynthesis, an important triterpenoid prevalent in Plantago species. The HPLC output further confirmed the higher concentration of ursolic acid in P. major as compared to P. ovata leaf samples, respectively. In addition to terpenoid biosynthesis, KEGG annotation revealed the involvement of differentially expressed unigenes in several metabolic pathways, aminoacyl-tRNA biosynthesis, biosynthesis of antibiotics, and biosynthesis of secondary metabolites. MYB was found as the most abundant transcription factor family in Plantago transcriptome. We have been able to generate valuable information which can help in improving terpenoid production in Plantago. Additionally, the present study has laid a strong foundation for deciphering other important metabolic pathways in Plantago.

Abstract
We report rheological characterisation of hydrogels formed by highly substituted brush-like arabinoxylans from Plantago ovata seed mucilage. Two arabinoxlyan fractions with similar molecular weight and linkage compositions are chosen to form gels with distinct rheological properties but a similar network structure. Small and large amplitude oscillatory shear rheology is used to characterise the sol-gel transition as a function of temperature and concentration. Differences in rheology and gelation of the two hydrogels are found to be associated with the different proportion of 'slow'- and 'fast'-dissociating junctions stabilised by hydrogen bonds, with the 'fast'-dissociating junctions playing an important role in rapid self-healing of the gel. Based on the temperature dependence of storage modulus and time-temperature superposition principle in combination with the Arrhenius equation, the activation energies of junction zone dissociation are estimated to be 402-480 kJ/mol and 97-144 kJ/mol for the 'slow' and 'fast' junction types, respectively.

Abstract
BACKGROUND Burn wounds are a worldwide health problem, leading to physical and psychological disabilities in all age's groups. With regard to absorbent properties of Plantago ovata mucilage which can decrease wound moisture, we aimed to compare the effect of silver sulfadiazine (SSD) 1% and powdered P. ovata on second-degree burn wound healing in rats. METHODS This experimental study was conducted on 30 male Wistar rats with second-degree burn in three groups. Group 1 (control) did not receive any treatment; group 2 and group 3 (treated groups) were dressed daily using SSD cream and P. ovata powder, respectively. The weight of rats, wound size (by applying ImageJ software) and percentage of wound healing on the 5th, 7th, 10th, 13th, 16th, 19th, and 22nd days (by diagnosing a plastic surgeon) and histological cutaneous changes at day 22 were evaluated. The Prism software was applied for data analysis. The Haematoxylin & Eosin as well as Masson's trichrome staining were performed on wound skin biopsies. RESULTS On day 22nd, 20%, 50% and 60% of the rats had complete wound healing in the control, SSD and P. ovata groups, respectively. A significant decrease in wound size was shown in the treated groups compared to the control group (P<0.01), but no significant difference was shown between the treated groups (P>0.05). CONCLUSION However, the wound healing in P. ovata group or SSD was better than the control group, and the significant difference was not found with the treated group.

Abstract
BACKGROUND Myxospermy is a process by which the external surfaces of seeds of many plant species produce mucilage-a polysaccharide-rich gel with numerous fundamental research and industrial applications. Due to its functional properties the mucilage can be difficult to remove from the seed and established methods for mucilage extraction are often incomplete, time-consuming and unnecessarily wasteful of precious seed stocks. RESULTS Here we tested the efficacy of several established protocols for seed mucilage extraction and then downsized and adapted the most effective elements into a rapid, small-scale extraction and analysis pipeline. Within 4 h, three chemically- and functionally-distinct mucilage fractions were obtained from myxospermous seeds. These fractions were used to study natural variation and demonstrate structure-function links, to screen for known mucilage quality markers in a field trial, and to identify research and industry-relevant lines from a large mutant population. CONCLUSION The use of this pipeline allows rapid analysis of mucilage characteristics from diverse myxospermous germplasm which can contribute to fundamental research into mucilage production and properties, quality testing for industrial manufacturing, and progressing breeding efforts in myxospermous crops.

Abstract
Dry eye disease is a relatively common eye disorder associated with decrease in quality of life. In this study, efficacy of an eye drop of Plantago ovata mucilage on symptoms of dry eye disease was evaluated. In a randomized, double-blind, placebo-controlled clinical trial, sixty dry eye patients with ocular symptoms and total Ocular Surface Disease Index (OSDI) score of ≥12 were randomly assigned to receive either a natural ophthalmic drop, made of Plantago ovata mucilage or placebo 4 times a day for 6 weeks. The patients were evaluated at pretreatment (baseline), weeks 4 and 6 post-treatment. The evaluation of the efficacy and safety were conducted based on the OSDI questionnaire, the noninvasive tear film break-up time (NI-BUT) with keratograph, the Schirmer test without anesthesia, and the osmolarity test, as well as by monitoring possible adverse events. After 6 weeks, within group analysis showed a significant improvement in total OSDI score (p < 0.001). In addition, between group comparison revealed a significant improvement in the OSDI score of the intervention group (p < 0.001). Although, NI-BUT was significantly improved in the Plantago ovata group (p = 0.004), however no statistically significant difference was observed in between group analysis. There were no significant differences between two groups, or significant changes within the groups in the Schirmer test without anesthesia and the osmolarity test. No serious adverse events were reported. In conclusion, P. ovata mucilage is a natural, inexpensiveness, and safe lubricant polymer that could have beneficial ocular effects on subjective symptoms of the patients with dry eye disease.

Abstract
Background Plants experience severe physiological stress from heavy metal pollution caused by improper discarding of the industrial wastes. Hexavalent chromium [Cr (VI)] is one of the major heavy metal pollutants in India and is present particularly in some regions where Plantago ovata grows to a great extent. This study was aimed at finding the effects of Cr (VI) on P. ovata and manoeuvres of the plant to combat such heavy metal exposure in vitro. Methods Potassium dichromate was used as a source of Cr (VI) to induce the heavy metal stress. Range of Cr (VI) sublethal doses [0 mM (control), 0.1 mM, 0.3 mM, 0.5 mM, 1 mM, 1.5 mM and1.8 mM] was used to observe its effect on the plant. The seeds of the plant were grown on sucrose-agar media with different concentrations of potassium dichromate, and ten-day old seedlings were then harvested and examined. Results The germination rate reduced below 50% at 1.9 mM Cr (VI) concentration and thus, 0 mM–1.8 mM concentration ranges were found to be suitable for sublethal dose. Morphological changes namely, reduction of the shoot-root length and multiple root development were caused by Cr (VI) in a dose-dependent manner. The plant showed elevated responses against Cr (VI), up to 1.5 mM (10 days treated) in terms of increasing accumulation of secondary metabolites like polyphenols, chlorophyll content (chlorophyll a, b and total chlorophyll), carotenoids and total antioxidant activity. DPPH radical scavenging activity along with malondialdehyde (MDA) content was not significantly elevated with the increase in Cr (VI) concentration indicating that the lipid peroxidation rate within the tissue was low. Phenylalanine ammonia lyase (PAL) and polyphenol oxidase (PPO) gene expressions were upregulated by 1 mM Cr (VI) concentration, which decreased at higher concentrations. The atomic absorption spectroscopy analysis also showed significant accumulation of Cr (VI) in the shoot and root with an increase in the potassium dichromate concentration. Conclusion Cr (VI) reduced the shoot-root length and seed germination in a dose-dependent manner. The plant system tried to combat the Cr (VI) stress by upregulating the stress response genes in the phenylpropanoid pathway along with an increase in polyphenol and antioxidant contents, which were evident from the lowering of lipid peroxidation rate and increase in PAL and PPO gene expressions.

Abstract
Two gel-forming arabinoxylan (AX) fractions with very similar linkage composition and molecular weight distributions have been isolated from Plantago ovata seed mucilage. Both isolated fractions have distinct gel properties attributed to differences in intermolecular hydrogen bonding. This study probes the effect of hydrogen bonding on molecular interactions of P. ovata AX fractions under non-gelled conditions achieved using a mild hydrogen bonding inhibitor, 0.2 M KOH. Chain conformation, relaxation dynamics and interactions between AX molecules are investigated using a combination of rheological techniques and small angle X-ray and neutron scattering. The scattering data confirm similar molecular dimensions and chain rigidity for both fractions, while showing distinct patterns of molecular interactions which result in the formation of a self-associated polymer network. The relationship between molecular associations, chain relaxation time and entanglement behaviour of P. ovata AX solutions are corroborated though the analysis of flow profiles and small amplitude oscillatory shear rheology.

Abstract
Mucilages are hydrocolloid solutions produced by plants for a variety of functions, including the creation of a water-holding barrier around seeds. Here we report our discovery of the formation of three distinct mucilage layers around Plantago ovata seeds upon their hydration. Each layer is dominated by different arabinoxylans (AXs). These AXs are unusual because they are highly branched and contain β-1,3-linked xylose in their side chains. We show that these AXs have similar monosaccharide and linkage composition, but vary in their polymer conformation. They also exhibit distinct rheological properties in aqueous solution, despite analytical techniques including NMR showing little difference between them. Using enzymatic hydrolysis and chaotropic solvents, we reveal that hydrogen bonding and side chain distribution are key factors underpinning the distinct rheological properties of these complex AXs.

Abstract
The enzymatic mechanism that governs the synthesis of the xylan backbone polymer, a linear chain of xylose residues connected by β-1,4 glycosidic linkages, has remained elusive. Xylan is a major constituent of many kinds of plant cell walls, and genetic studies have identified multiple genes that affect xylan formation. In this study, we investigate several homologs of one of these previously identified xylan-related genes, IRX10 from Arabidopsis thaliana, by heterologous expression and in vitro xylan xylosyltransferase assay. We find that an IRX10 homolog from the moss Physcomitrella patens displays robust activity, and we show that the xylosidic linkage formed is a β-1,4 linkage, establishing this protein as a xylan β-1,4-xylosyltransferase. We also find lower but reproducible xylan xylosyltransferase activity with A. thaliana IRX10 and with a homolog from the dicot plant Plantago ovata, showing that xylan xylosyltransferase activity is conserved over large evolutionary distance for these proteins.

Abstract
INTRODUCTION Comprehensive chemical profiling of herbal medicines (HMs) is a major challenge in chemical characterisation of source materials. Many analytical platforms such as gas chromatography-mass spectrometry (GC-MS) have been applied to the characterisation. However, the great complexity of analytical results has been an obstacle. Chemometric resolution methods as a supplementary tool for data processing are proposed for solving this problem. OBJECTIVE To develop and demonstrate the ability of chemometric techniques in the characterisation of volatile components in herbal medicines. METHODS The volatile components of Plantago ovata were extracted using a solvent extraction method. GC-MS analysis were performed using an Agilent HP-6890 gas chromatograph equipped with a HP-5MS capillary, interfaced with an Agilent HP- 5973 mass selective detector. Resolved spectra were identified by matching against the standard mass spectral database of the National Institute of Standards and Technology (NIST). RESULTS Results of this study show that the 71 constituents that are qualitatively recognised represent 94.53% of the total relative content of constituents from Plantago ovata oil, whereas without applying the chemometric methods only 51 constituents were recognised by direct searching utilising a mass database. In addition the presence of valuable components such as thymol, 2,4-decadienal, linoleic acid and oleic acid in Plantago ovata oil has been demonstrated. CONCLUSION GC-MS combined with chemometric resolution methods, such as multivariate curve resolution-alternating least squares (MCR-ALS), will provide a reliable means for rapid and accurate analyses of unknown complicated practical systems.

Abstract
Plantago ovata Forsk. (isabgol) is a valuable medicinal plant; its seeds and shell have a significant role in pharmacy as a laxative compound. Increasing soil contamination with cadmium (Cd) is one of the major concerns and is responsible for toxic effects in plants. This investigation was aimed to analyze the role of biofertilizers in alleviation of cadmium stress, given at the rate of 0, 50, and 100 mg kg(-1) of soil. The plants of isabgol, were grown in pots with and without application of AM fungi and Azotobacter (alone and combination). Cadmium showed negative effect on growth and biochemical component whereas proline and MDA content increase with increasing cadmium concentration. Addition of bio-fertilizer showed better growth and higher pigment concentration under cadmium stress as compared to the control. The dual inoculation of AM fungi and Azotobacter was found to be the best in reduction of cadmium stress and promotion of growth parameters.
