The primary objective of this experiment was to assess the influence of varying levels of phosphorus, in conjunction with the application of Phosphorus Solubilizing Bacteria (PSB), on the growth and yield parameters of field pea. This research was undertaken using a randomized block design, with a factorial arrangement that was replicated three times to ensure the reliability and robustness of the findings. The experiment encompassed seven distinct treatment combinations, which spanned the spectrum from a control group to different percentages of the recommended dose of phosphorus (RDF), including 100%, 80%, 60%, 40%, and 20% of the RDF. The results obtained from this meticulous study unveiled significant impacts of phosphorus levels and the application of Pho...

Objective: To study the immunomodulatory functions of the aqueous extract of the seeds of Abrus precatorius commonly known as Indian liquorice (Fabaceae), a medicinal plant native to central India. Methods: Swiss albino mice were intraperitoneally treated with three doses (0.75, 1.25 and 2.5 µg/kg b.w.) of extract for 7 days. Relative organ weight, delayed type hypersensitivity (DTH) response, haemagglutination titre (HT) and Phagocytic index (PI) were studied in various groups of animals. Results: The results showed no significant difference in relative organ weight of spleen, liver, thymus and kidney in various groups of animals. Treatment of rats with increasing concentrations of the extract decreased the footpad thickness indicating a dose related inhibitory effect of the extract on delayed type hypersensitivity. In the HT test, the plant extract showed a suppressive effect at all doses, and these changes were significant as the dose increased. Phagocytic index was also increased in a dose dependent manner. Conclusion: The reduction of antibody titre, delayed type hypersensitivity response and the increase in phagocytic index indicates that Abrus precatorius has an inhibitory effect on the immune functions in mice.

The extract showed strong anticomplementary effects which were dose-and time-dependent and most pronounced in the classical complement pathway assay. Moreover, a dose-dependent decrease in the chemiluminescence of polymorphonuclear leukocytes was observed and a dose-dependent increase in the production of migration inhibition factor by lymphocytes.

Though their active role in the lentil agroecosystem is not well defined, here we observed that these NREs might promote the growth of lentils, modulate rhizospheric community structure and could be used as promising organisms for optimal use of rice fallow soil. NREs from root nodules of lentils were isolated and examined for plant growth-promoting traits, exopolysaccharide (EPS) and biofilm production, root metabolites, and the presence of nifH and nifK elements. The greenhouse experiment with the chosen NREs, i.e., Serratia plymuthica 33GS and Serratia sp. R6 significantly increased the germination rate, vigour index, development of nodules (in non-sterile soil) and fresh weight of nodules (33GS 94%, R6 61% growth) and length of the shoot (33GS 86%, R6 51.16%) as well as chlorophyll levels when compared to the uninoculated control. Scanning Electron Microscopy (SEM) revealed that both isolates coul...

In addition to personal hygiene, this technology facilitates public hygiene as antimicrobial tiles can be installed at hospitals, schools, banks, offices, lobbies, railway stations, etc. This review is primarily focused on preparing antimicrobial tiles using an antimicrobial layer or coatings that fight against germs. The salient features and working mechanisms of antimicrobial tiles are highlighted. This challenge is a component of the exploratory nature of nanoarchitectonics, that also extends farther than the realm of nanotechnology. This nanoarchitectonics has been successful at the laboratory scale as antimicrobial metal nanoparticles are mainly used as additives in preparing tiles. A detailed description of various materials for developing unique antimicrobial tiles is reported here. Pure metal (Ag, Zn) nanoparticles and a mixture of nanoparticles with other inorganic materials (SiO 2, , TiO 2 , anatase, nepheline) have been predominantly used to combat microbes. The developed antimicrobial tiles have shown excellent activity against a wide range of Gram-positive and Gram-negative bacteria. The last section discussed a hypothetical overview of utilizing the antimicrobial tiles against SARS-CoV-2. Overall, this review gives descriptive knowledge about the importance of antimicrobial tiles to create a clean and sustainable environment.

Saraca asoca has many uses mainly in the ayurvedic medicine. The endophytic fungus have developed a strong bonding with the plant during the co-evolution between them which resulted in production of bioactive Secondary metabolites which are originally the phytochemicals associated with the host plant. The aim of the present study was to isolate and observe antibacterial activity of the endophytic fungi against some pathogenic bacteria. Endophytic fungi (Syncephalastrum rasemosum, Syncephalastrum racemosums328) were isolated from mature healthy leaves and bark of medicinal plant Saraca asoca were collected from the Human Herbal Garden in M.P. Council of Science and Technology, Bhopal, Madhya Pradesh (India). Screening of endophytic fungi for in-vitro antibacterial activity against three pathogenic bacteria i.e. Streptococcus mutans, Lactobacillus acidophilus and...

The plant has become endangered due to its unscientifically exploitation and high medicinal values. In the Present study 10 randomly amplified polymorphic DNA (RAPD) and 6 ISSR markers were employed to assess genetic divergence among micro propagated, wild and field cultivated plants of Gloriosa superba collected from different parts of India. In RAPD analysis, all the 10 accession with 10 RAPD primers amplified 466 fragments, with 96.43 % polymorphism and with an average of 46.6 bands per primer. The size of amplicons varied from 1656 to 100 bp. While, ISSR primers produced 328 fragments of which 298 were polymorphic with an average of 49.7 bands per primer with 91.83% polymorphism. The size of amplicons ranges from 2395 to 181 bp. RAPD, ISSR markers were also assessed by calculating polymorphic information content (PIC) to discriminate the genotypes, Average PIC value for RAPD, ISSR and combined RAPD + ISSR markers obtained was ≤ 0.50 suggesting the informativeness of markers. Jaccard's coefficient ranges from 0.18 to 0.75 (RAPD) and 0.17 to 0.61 (ISSR) and 0.21-0.52 for pooled ISSR and RAPD markers. The clustering pattern based on UPGMA analysis of the genotypes in the combined analysis revealed that the majority of the genotypes remained similar to the ISSR dendrogram, while the RAPD-based dendrogram showed some variation in the clustering of genotypes. The result of PCA scattered plot obtained were in agreement with the UPGMA dendrogram, which further confirms the genetic relationships explain by cluster analysis. Results confirmed that the genotype studied had good genetic diversity and can be used for identification, conservation, and future breeding program of Gloriosa species and consequently for the benefit of the pharmaceutical industries.

The objective of this study was to undertake, analyze, and characterize the microbiome of two major hot springs located in the state of Madhya Pradesh explicitly, Chhoti Anhoni (Hotspring 1), and Badi Anhoni (Hotspring 2) to find out the inhabitant microbial population, and their functional characteristics. The taxonomic analysis of the microbiome of the hot springs revealed the phylum Proteobacteria was the most abundant taxa in both the hot-springs, however, its abundance in hot-spring 1 (~88%) was more than the hot-spring 2 (~52%). The phylum Bacteroides (~10–22%) was found to be the second most abundant group in the hot-springs followed by Spirocheates (~2–11%), Firmicutes (~6–8%), Chloroflexi (1–5%), etc. The functional analysis of the microbiome revealed different features related to several functions including metab...
