Plant growth promoting rhizobacteria can affect plant growth by different direct and indirect mechanisms [1]. PGPR influence direct growth promotion of plants by fixing atmospheric nitrogen, solubilizing insoluble phosphates, secreting hormones such as IAA, GAs, and Kinetics besides ACC deaminase production, which helps in regulation of ethylene. Induced systemic resistance (ISR), antibiosis, c...

Plant-growth-promoting rhizobacteria (PGPRs) are used as inoculants for biofertilization, phytostimulation and biocontrol. The interactions of PGPRs with their biotic environment, for example with plants and microorganisms, are often complex. Substantial advances in elucidating the genetic basis of the beneficial effects of PGPRs on plants have been made, some from whole-genome sequencing proje...

the effects of plant growth promoting rhizobacteria (pgpr) on growth and physiological characteristics of seedlings corylus avellana were determined in a forest nursery. for this purpose, in a completely randomized design (crd) and four replicates, three putative bacteria, including pseudomonas putida, bacillus subtilis and enterobacter cloacae, as alone and mixed, were examined. the greatest h...

As a natural engineer, Plant Growth Promoting Rhizobacteria (PGPR) play an important role in increasing plant growth, yield and enhancing tolerance to stressful conditions. These beneficial bacteria take up their position the rhizosphere, around plants’ root tissues. They may be in, or on host tissues help provide nutrients plants. For sustainable agriculture, PGPR transmit extensive assistance...

in order to study the effects of growth promoting bacteria (gpr) and mycorrhizal fungi on seedling emergence, establishment and growth of two ecotypes alfalfa under salinity stress condition, an experiment was conducted in greenhouse of college of agriculture and natural resources, university of tehran in summer 2011. the experiment was arranged as a factorial with three replications. experimen...

In their natural environment, plants experience multiple biotic interactions and respond to this complexity in an integrated manner. Therefore, plant responses to herbivory are flexible and depend on the context and complexity in which they occur. For example, plant growth promoting rhizobacteria (PGPR) can enhance plant growth and induce resistance against microbial pathogens and herbivorous i...
