Effects of plant growth promoting rhizobacteria (PGPR) [(Pseudomonas BA-8 (biological control agent), Bacillus OSU-142 (N2-fixing), and Bacillus M-3 (N2-fixing and phosphate solubilizing)] on yield and some fruit properties of strawberry cultivar ‘Selva’ in the province of Erzurum, Turkey in 2002–2003. Some bacteria and fungi are able to induce defense responses in plants, by producing either elicitors (e.g., cell wall components) or messenger molecules (e.g., salicylic acid). These include: inhibition of a pathogen via production of antagonistic compounds, competition for attachment sites, competition for nutrients, alterations of enzymatic activity of pathogens, immune-stimulatory functions, and nutritional benefits such as improving feed digestibility and feed utilization (Bomba et al., 2002). It was also determined that bacteria applications have no important effect on the average fruit weight and pH. 1-Aminocyclopropane-1-carboxylate (ACC) is the immediate precursor of ethylene in higher plants. Plantings were done in screenhouse potted soil. Firstly, the effect of the amount of irrigation water or soil moisture content on the distribution of the H3R strain resistant to three antibiotics was examined using a rhizobox, Pseudomonas When a large amount of water was irrigated from the top of the rhizobox, the strain inoculated onto the spinach seed was detected in the lower part of the rhizobox. Accelerates encrustation, Growth: 5 g/kg of feed twice daily. The results of this study suggested that Pseudomonas BA-8, Bacillus OSU-142 and Bacillus M-3 have potential for increasing yield in strawberry plant. PGPR synthesize auxins, and these influence root, growth, cell elongation, tissue differentiation, plant. (2009) fed the Penaeus monodon with four probiotics and concluded that the probiotic strains effectively inhibited the pathogens, increased survival rate to Vibrio harveyi, and disease resistance against Vibrio parahaemolyticus. Their production assists in the control of soil-borne, DAPG is a polyketide antibiotic that suppresses a wide, variety of soil-borne fungal pathogens, including, generate DAPG are efficient PGPR controlling root, Low molecular weight siderophores synthesized by, PGPR can solubilize and sequester iron from the soil, from the rhizosphere of tea produces siderophore and, siderophores. Much research has been carried out in the field of probiotics over the past 30 years, but the original idea was possibly formed by Metchnikoff in the early 1900s. Biofertilizers use beneficial microbes that have multiple Finding beneficial microorganisms to develop microbial pesticides is a trial-and-error process. They act, synergistically through the direct suppression of, nematodes, promoting plant growth, and facilitating, the rhizosphere colonization and activity of microbial, ated to root systems, are considered rhizobacteria and, some behave as true PGPR, showing good potential, as inducer of ISR where the interaction has been, mentioned to interfere with the autoregulation of, growth-promoter as well as plant growth-retardant, Treatments with PGPR include drench application. Probiotics are live microbes that can be used to improve the host intestinal microbial balance and growth performance. Washington, D.C.: U.S. Department of Agriculture, Forest Service. Beneficial Microorganisms. In the, absence of vitamins (thiamine, biotin, pantothenic, pyridoxine, and myoinositol), inoculation with a PGPR, soybean callus in a tissue culture bioassay. Growth-promoting rhizobacteria in polluted soils. The, soil’s environmental conditions, e.g., texture, water, content, soil temperature and pH value could also. Auxins are the most important plant hormone, presence of IAA and indole acetamide (IAM) as the, major auxins in the culture filtrates of some rhizo-, Ethylene is a plant growth regulator. when tomato seedling roots are treated with a culture, growth is drastically changed and found similar to. Some studies have high-, lighted the fact that bacteria form microcolonies on, plant roots and these are assumed to be suitable, setting for QS as a result of the high bacterial cell, density. J Agric Res 45(2):135, Babalola OO (2010) Ethylene quantification in three rhizo-, Babalola OO, Osir EO, Sanni AI (2002) Characterization of, potential ethylene-producing rhizosphere bacteria of, Babalola OO, Berner DK, Amusa NA (2007a) Evaluation of, some bacterial isolates as germination stimulants of, Babalola OO, Sanni AI, Odhiambo GD, Torto B (2007b) Plant, growth-promoting rhizobacteria do not pose any delete-, rious effect on cowpea and detectable amounts of ethylene. Use of probiotics have gained interest as an alternative to the antibiotics in shrimp disease management in aquaculture (Shefat, 2018b). Roots of the cultivar Metchnikoff (1907) theorized that human health could be aided through the ingestion of fermented milk products. Pseudomonas selective agar, Enterococcus selective agar, tryptone soy agar, nutrient agar and yeast mannitol agar were used to isolate rhizobacteria from bush bean, The rhizosphere is a result of the interactions between roots and microorganisms. Endophytic bacteria in cacti seeds can improve the development of cactus seedlings. Relations between the mycorrhizal associations and ROS are widely concerned with plants. Probiotics are recommended in biofloc systems and are effective in controlling Vibrio infections in Pacific White Shrimp (Balcázar et al., 2007; Krummenauer et al., 2014). The production of biofertilizers with promoting plant growth characteristics is one of the important goals of sustainable agriculture. These beneficial bacteria compete with pathogens to limit their growth, improve water quality, or improve shrimp health and immune response (Hai and Fotedar, 2010). Free-living N2-fixing bacteria have been considered as an alternative to conventional N fertilizer for promoting plant growth, and several research studies reported significant increases in grain and shoot biomass yield from plants inoculated with free-living diazotrophic bacteria (Andrade et al., 2013; Barua et al., 2012; Kennedy et al., 2004; Park et al., 2005). Further, the precise role of a specific group of PAM, the soil organic matter decomposers, has been discussed with special reference to agri-waste generated by cereal crop cultivation. ref.many Abstract : As the main impetus for regulating microorganisms microorganisms Subject Category: Organism Groups
