The Methanolic Extract of Boesenbergia Rotunda (L.) Mansf. Ultrasonic-assisted extraction was used to attain total ethanol-water extract. All extracts displayed a good radical-scaveng-ing activity at the concentration range 1-300 g/mL in the following order: Auricularia delicata > Lentinus cf cladopus > Pleurotus tuberregium > Ma-rasmius buzungolo > Schizophillum commune. Lu C., Shen Y. Many of these metabolites are also derived from endophytic bacteria. Therefore, bacterial endophytes have commercial potential in bioproduction and biotransformation of ginsenocides for use as anti-viral agents. Antimicrobial activity was determined as relative percentage inhibition (RPI), minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). International Journal of Veterinary Science. Ezra D., Castillo U.F., Strobel G.A., Hess W.M., Porter H., Jensen J.B., Condron M.A.M., Teplow D.B., Sears J., Maranta M., et al. Endophytic Actinomycetes have been isolated from several Chinese medicinal and mangrove plants with antimicrobial activities against the bacterial pathogens Enterobacter faecalis, Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli, Acinetobacter baumanni, Pseudomonas aeroginasa and some multidrug resistant human pathogens [73]. According to a recent report, cancer is the leading cause of death worldwide, accounting for nearly 10 million deaths in 2020 [105]. Secondary metabolites, including terpenes, phenolics and nitrogen (N) and sulphur (S) containing compounds, defend plants against a variety of herbivores and pathogenic microorganisms as well as various kinds of abiotic stresses.

This book is a must-read for science students, research scholars and scientific community who are interested in plant science. The authors hypothesize that endophytes may be selected by their antimicrobial resistance phenotypes as a response to antimicrobial metabolites produced by microorganisms in the same niche [96], suggesting that these microorganisms could indeed be a source of new antibiotics and antibiotic resistant mechanisms. Segers K., Declerck S., Mangelings D., Heyden Y.V., Eeckhaut A.V. Pseudomonas syringae, another endophytic bacterium associated with many plants, can produce pseudomycins, a group of antifungal peptides containing non-traditional amino acids with strong activity against human and plant pathogenic fungi [93]. Secondary metabolites constitute plants' weaponry against pests and pathogens invasion. can kidney disease cause low blood pressure leith community treatment centre gp middlesex school basketball dickies mens relaxed straight-fit lightweight duck carpenter jean. Studies conducted on different plant-metabolites reported that these metabolite can potentially combat plant pathogens. Streptomyces strains NRRL30566 and GT2002/1503 isolated from the fern-leaved Grevillea tree and mangrove plants, respectively, have produced kakadumycins and xiamycins which have strong antimicrobial activities against several otherwise drug resistant bacteria [73,83]. As a result of their significant impact as curative compounds or as precursors to produce new drugs, the biotechnological possibilities of secondary metabolites derived from endophytic bacteria are immense. Moreover, the detection of alkaloids such as ismine, lycoramine, haemanthamine, tazettine, galanthamine, lycorine, homolycorine and hippeastrine in the extracts of this bacterium highlights the role of bacterial endophytes in the production of alkaloids for biotechnological and therapeutic applications. and transmitted securely. This bacterium is, therefore, a good candidate for further research on its capacity to produce major ginsenosides such as Rb1, Rb2, Rc, Rd, Re and Rg1.

More specifically, the traditional values of therapeutic plants are correlated with scientific approach for the validation of drug- like properties. Ethylene and Abiotic Stress Tolerance in Plants. Polyene antibiotic. Endophytes as Sources of Bioactive Products. These mechanisms include (but may not be limited to) the production of molecules involved in inorganic phosphate and potassium solubilization (e.g., various low molecular weight organic acids); synthesis of siderophores (chelating agents) that sequester iron from the soil and provide it to plants; synthesis of gibberelins and cytokinins (phytohormones that regulate various plant developmental processes); synthesis of auxins (such as indole 3-acetic acid, the most common auxin) which are phytohormones that promote plant cell elongation and proliferation; synthesis of the unusual and highly stable water-structuring sugar molecule trehalose which can help the plant to lower (overcome) salt and drought stress; the ability to fix atmospheric nitrogen into the ammonia which is necessary to synthesize proteins and nucleic acids; and synthesis of the enzyme 1-aminocyclopropane-1-caroxylate (ACC) deaminase which lowers plant ethylene levels, thereby decreasing the inhibitory effects of various abiotic stresses (see Section 2.5). Advantages of endophytic growth include protection from competing bacteria and fungi, a constant and reliable source of nutrition, and protection from exposure to a wide range of potentially deleterious environmental conditions, such as extremes of temperature and the presence of inhibitory chemicals in the soil. Secondary metabolites most often play a principal position in plant safety towards herbivory and other interspecies defenses. Bacterial endophytes employ a wide range of mechanisms, following their interaction with plants, where they directly promote plant growth and development. National Library of Medicine ; Writing- review and editing, Z.N. Pigments from endophytic bacteria are being explored as sources of new drugs to treat antibiotic resistant pathogens [103].

Screening of Endophytic Bacteria Isolated from Leaves of Sambung Nyawa [Gynura Procumbens (Lour.) Moreover, while endophytic PGPB are attracted to a specific plants root exudates [19,20] and enter the plant through the roots, many of these bacteria are motile and can travel through the plant to other tissues such as leaves and stems (where they are generally found in lower concentration than in the plant roots). Qualitative and quantitative estimation of the flavonoid components of the plant Althaea Officinalis were done by using HPLC. Nutrition is an important aspect of public health because it is linked to many significant diseases and health problems. [144] have shown that Leucojum aestivum, a plant with therapeutic properties, inoculated with endophytic Paenibacillus lautus isolated from in vitro grown L. aestivum plants, had increased levels of galanthamine and lycorine alkaloids. Growth Enhancement and Drought Tolerance of Hybrid Poplar upon Inoculation with Endophyte Consortia. It has been estimated that nearly all the worlds ~300,00 plant species [18] contain several different endophytic bacteria (~105 108 cells per gram of plant tissue) as well as numerous fungal endophytes.
