abstract soil beneficial microorganisms such as plant growth promoting rhizobacteria (pgpr) are able to enhance plant growth. the research was conducted using a randomized complete block design as split plot factorial with three factors (nutrient management, azospirillum and azotobacter strains) .in this experiment the effect of azospirillum and azotobacter inoculation on yield and yield compon...

Aim: To evaluate the effect of co-inoculation with Pseudomonas fluorescens and P. + Azospirillum brasilense on seedling emergence speed, development soybean yield.
 Study Design: Randomized complete block design five treatments eight replications.
 Place Duration Study: Ibiporã, Paraná State, Brazil, during 2020/21 season.
 Methodology: The consisted untreated control (Cont); min...

Nitrogen (N) fertilization is a crucial agricultural practice for boosting production traits in vegetables. However, N synthetic fertilizers—commonly adopted by farmers—have several counterproductive effects on the environment and humans. The research was performed to assess combined influence of plant growth promoting bacteria (PGPB) (Azospirillum brasilense DSM 1690, A. 2298 Pseudomonas sp. 2...

The Che1 chemotaxis-like pathway of Azospirillum brasilense contributes to chemotaxis and aerotaxis, and it has also been found to contribute to regulating changes in cell surface adhesive properties that affect the propensity of cells to clump and to flocculate. The exact contribution of Che1 to the control of chemotaxis and flocculation in A. brasilense remains poorly understood. Here, we sho...

Although Azospirillum spp. are considered to be important plant growth promoting bacteria, their possible effects on germination and vigor of aged lettuce seeds has not been previously evaluated. In fact, there is a paucity of published data about inoculation effects on seed germination. The aim of this work was to evaluate seed quality of oneyear aged lettuce (Lactuca sativa L. cv. Crimor INTA...

Tn5 mutagenesis was used to generate an Azospirillum brasilense SPF94 mutant. Genetic analysis of this mutant revealed that a homologue of the mreB gene, which controls cell shape in Bacillus subtilis and Escherichia coli, was inactivated. The cell-surface properties of the mutant were different from those of the parental strain. The mutant colonies were highly fluorescent when grown on plates ...

Fructose uptake and catabolism in Azospirillum brasilense is dependent on three fructose-inducible enzymes (fru-enzymes): (i) enzyme I and (ii) enzyme II of the phosphoenolpyruvate:fructose phosphotransferase system and (iii) 1-phosphofructokinase. In minimal medium containing 3.7 mM succinate and 22 mM fructose as sources of carbon, growth of A. brasilense was diauxic, succinate being utilized...

Given the hypothesis that co-inoculation with plant growth-promoting bacteria (PGPB) enhances beneficial effects of Rhizobium tropici greater mineral nutrition, optimizes biological nitrogen fixation and reduces use fertilizers in bean plants, objective this research was to evaluate synergistic associated Azospirillum brasilense, Bacillus subtilis, Pseudomonas fluorescens their combinations, on...

Bu çalışma, Van ekolojik koşullarında biyogübre uygulamaları ve inorganik gübrelemenin aspir (Carthamus tinctorius L.) bitkisinin bazı agronomik özellikleri üzerine etkilerini belirlemek amacıyla 2020 2021 yılları yazlık yetiştirme döneminde sulu koşullarda yürütülmüştür. Araştırma Yüzüncü Yıl Üniversitesi Ziraat Fakültesi deneme alanlarında Tesadüf Bloklarında Bölünmüş Parseller Deneme Deseni’...
