Sanity diagnostic require to know if exist beneficial microorganism and what agricultural practices help to their propagation. Approach: Samples (30) were taken from soils and sick plants of ten sites in four localities of Valley of Poanas. Phytophthora capsici Leo, Rhizoctonia solani Kuhn and … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 4 Jun 2011 · 8,542 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExpression, Purification and Activity Assay of Two New Recombinant Antagonists of Fibrinogen ReceptorJianbo Yang, Jia Yao, Kun Yang et al.The gene sequence of Decorsin which is extracted from a kind of North American leeches was synthesized. Two recombinant proteins, Annexin V plus Decorsin (AnnV-D39) and Annexin V plus the carboxyl terminal 27 amino acid residues of Decorsin(AnnV-D27), were constructed. And a 10 amino acids linker peptide of GGGGSGGGGS was inserted between Annexin V and Decorsin in AnnV-D39. Using pET-28(a+) … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,913 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiocontrol of Winter Wheat Root Rot by Rhizosphere Microorganisms in KazakhstanNurlan Kuldybayev, Amankeldy Sadanov, Aigerim Qairatova et al.Root rot remains one of the most significant diseases of winter wheat (Triticum aestivum L.) in Kazakhstan, resulting in substantial yield losses. This study aimed to isolate and identify rhizosphere microorganisms associated with winter wheat and evaluate their antagonistic activity against root rot pathogens in the Almaty region of Kazakhstan. In total, seven bacterial and fungal isolates, belonging to the … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 25 Aug 2026 · 933 accessesView PDFCite
Research ArticleOpen accessIn the abstractPromising Biocontrol Agents Against the Main Pathogens of Apple Fruit RotElvira Ismailova, Nurlan Kuldybayev, Gul Baimakhanova et al.Current study looked into how well microorganisms, both those already known and newly found, from the surface of plants in gardens in southern and southeastern Kazakhstan could fight against other harmful microbes. We evaluated the effectiveness of 16 strains of lactic acid bacteria, 11 strains from the Bacillus and Pseudomonas genera, and 7 strains of Trichoderma fungi (all sourced from … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 25 Aug 2026 · 864 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of New Molecules Having Antiemetic Activity Using Molecular ModelingKhalil Errahmane Kanouni, Yacine BenguerbaThe solubility of a drug in water or in the blood represents the most desired parameter in medicine. Our aim is to obtain molecules with properties more effective than those of metoclopramide. In this work, two molecules with high solubility are constructed. Metoclopramide (a benzamide derivative) is a dopamine receptor antagonist used as an antiemetic drug. Its solubility in water … …Current Research in Bioinformatics, Vol. 8, Issue 1 · 27 Feb 2020 · 6,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractHepatoprotective Impact Of TLR9 Antagonist ODN 2088 Against Carbon Tetrachloride (CCl4)-Induced Hepatic InjuryBadr AlzahraniThe main objective of this study is to evaluate the hepatoprotective impact of TLR9 antagonist ODN 2088 against carbon tetrachloride (CCl4)-induced acute liver injury. In this study, 24 mice were grouped into four groups. CCl4 was introduced in all groups except for the control group intraperitoneally after pretreatment with ODN 2088 and silymarin for seven days. To assess the liver … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 4 Jan 2020 · 7,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vitro Antagonistic Antifungal-Activity of Streptomyces Isolate 339 Against Magnaporthe oryzaeM. Ebrahimi Zarandi, G. H. Shahidi Bonjar, F. Padasht DehkaeiBiological control offers an environmentally friendly alternative to the use of antimicrobials for controlling plant diseases. A collection of about 100 Actinomycete strains was screened for the ability to produce metabolites that inhibit Magnaporthe oryzae growth in vitro. The Streptomyces isolate 339 showed strong in vitro antagonistic activity against M. oryzae in Agar disc and Well-diffusion methods by producing extracellular … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 3 · 4 Sep 2013 · 8,140 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrowth Enhancement and Disease Reduction of Soybean by 1-Aminocyclopropane-1-Carboxylate Deaminase-Producing PseudomonasEdi Husen, Aris Tri Wahyudi, Antonius Suwanto, GiyantoProblem statement: 1-Aminocyclopropane-1-Carboxylate (ACC) deaminase-producing bacteria have been known to ameliorate the inhibition-effect of increase concentration of ethylene in higher plants, which can be triggered by high concentration of indole-3-Acetic Acid (IAA) and/or by the presence of plant pathogens. This study examined the potential use of Pseudomonas isolates producing ACC deaminase as well as IAA to enhance soybean growth and … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 23 Sep 2011 · 7,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiocontrol of Soil Fungi in Tomato with Microencapsulates Containing Bacillus subtilisMarcela Hernàndez-Suàrez, Francisco Daniel Hernàndez-Castillo, Gabriel Gallegos-Morales et al.Problem Statement: An option to reduce pollution by synthetic agro-chemical in root plant disease management is the use of antagonist rhizobacteria belonging to Bacillus genus, because their inhibitory properties, stimulation of plant growth and crop yield increase. Approach: This study was carried out in order to evaluate if Bacillus subtilis strains could play an antagonists role of plant pathogens and … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,925 accessesView PDFCite
