Bacteria that colonize plant roots and promote growth are referred to as growth-promoting rhizobacteria (PGPR). PGPR highly diverse in this review we focus on biocontrol agents. Their effects can occur via local antagonism soil-borne pathogens or by induction of systemic resistance against throughout the entire plant. Several substances produced antagonistic have been related pathogen control indirect promotion many plants, such siderophores antibiotics. Induced (ISR) plants resembles...
Knowledge on biodiversity is fundamental for conservation strategies. The Brazilian Pampa region, located in subtropical southern Brazil, neglected terms of conservation, and knowledge its fragmented. We aim to answer the question: how many, which, species occur Pampa? In a collaborative effort, we built lists plants, animals, bacteria, fungi that Pampa. included information distribution patterns, main habitat types, status. Our study resulted referenced totaling 12,503 (12,854 taxa, when...
A bacterial strain designated SBR5 T was isolated from the rhizosphere of Triticum aestivum . phylogenetic analysis based on 16S rRNA gene sequence placed isolate within genus Paenibacillus , being most closely related to graminis RSA19 (98.1 % similarity). The a Gram-reaction-variable, motile, facultatively anaerobic bacterium, with spores in terminal position cells. Starch utilized and dihydroxyacetone catalase were produced. Strain displayed plant-growth-promoting rhizobacteria...
The nature of the soil is shaped by presence roots and microbiota. Bacteria, archaea fungi profoundly alter plant growth and, in turn, depend on root exudation carbon-rich energy-yielding compounds. microbial communities act as facilitators processes secreting regulators, solubilizing minerals, providing N for growth, altering immune responses competing with pathogens. Characterizing engineering driven multiple taxa that make [...]
The nitrogen fixation by strains belonging to the Bacillus genus remains poorly explored. In this work, diversity of endospore-forming bacilli isolated from rhizosphere sunflower was evaluated. A total 101 were identified based on V1-V2 variable regions 16S rRNA gene. Strains genera and Paenibacillus represented 41.6% 58.4%, respectively, isolates. production indolic compounds a common trait among isolates, approximately 75% them exhibited positive nitrogenase activity; but only 9.2%...
Paenibacillus isolates were selected to test antimicrobial activity against bacteria, filamentous fungi and yeasts isolates, with the purpose of finding new bacterium species for microbiological control.Fifty-five strains belonging 15 inoculated on trypticase soya agar, potato dextrose agar sabouraud plates in order evaluate their 16 indicator 14 six both reference field strains. After these screening, culture supernatant 17 was prepared. Twenty-five presented activity, where seven...
In the last decades, use of plant growth-promoting rhizobacteria has become an alternative to improve crop production. Rhizobium leguminosarum biovar trifolii is one most promising and even used with non-legume plants. This study investigated in vitro occurrence characteristics several indigenous R. isolated from soils State Rio Grande do Sul, Brazil. Isolates were obtained at 11 locations evaluated for indoleacetic acid siderophore production inorganic phosphate solubilization. Ten isolates...
Two bacterial strains that amplified part of the nifH gene, RP1p and RP2p, belonging to genus Enterobacter Serratia, were isolated from rhizoplane Lupinus albescens. These bacteria are Gram-negative, rod-shaped, motile, facultative anaerobic, fast-growing; colonies reach diameters 3-4 mm within 24 h incubation at 28 ºC. The also able grow temperatures as high 40 ºC, in presence (2-3 % w/v) NaCl concentrations pH 4 -10. Strain was utilize 10 14 C sources, while RP2p utilized nine. isolates...
In the pursuit of sustainable agriculture, bioinoculants usage as providers a crop's needs is method to limit environmental damage. this study, collection cultivable putative plant growth promoting (PGP) bacteria associated with wheat crops was obtained and bacterial sample characterized in relation functional diversity certain PGP features. The isolates were through classical cultivation methods, identified by partial 16S rRNA gene sequencing for traits interest. Functional characterization...
