Several microbes promote plant growth, and many microbial products that stimulate plant growth have been marketed. In this review we re-strict ourselves to bacteria that are derived from and exert this effect on the root. Such bacteria are generally designated as PGPR (plant-growth-promoting rhizobacteria). Plant Growth Promoting Rhizobacteria (PGPR) increase plant growth under some conditions and have beneficial effects on plants. PGPR are a very small portion of rhizobacteria (%) (Antoun, ).

Aims: Plant growth promoting rhizobacteria (PGPR) are commonly used as inoculants for improving the growth and yield of agricultural crops, however screening for the selection of effective PGPR strains is very critical. This study focuses on the screening of effective PGPR strains on the basis of their potential for in vitro auxin production and plant growth promoting Cited by:
Thus, melatonin and plant‐growth‐promoting rhizobacteria are involved in enhancing plant growth under abiotic and biotic stress but the mechanisms of action of both are different. Therefore, in this study, the data on the impact of melatonin and plant‐growth‐promoting rhizobacteria on plants are combined for the first time and how these Cited by: 2. Plant growth-promoting bacteria (PGPB) are bacteria that can enhance plant growth and protect plants from disease and abiotic stresses through a wide variety of mechanisms; those that establish close associations with plants, such as the endophytes, could be more successful in plant growth promotion. Plant growth promoting rhizobacteria (PGPR) shows an important role in the sustainable agriculture industry. The increasing demand for crop production with a significant reduction of synthetic chemical fertilizers and pesticides use is a big challenge by: Therefore, in present study plant growth promoting rhizobacteria Bacillus subtilis strain MA-2 and Pseudomonas fluorescence strain MA-4 were efficient in phosphate solubilization and indole acetic acidity (IAA) (Fig. 1) production and considerably elevated biomass 9% and % correspondingly of medicinal and aromatic plant for example Geranium.
Plant-growth-promoting rhizobacteria (PGPR), arise the mechanism of interaction with each other on plants surfaces and plants make the association with a guild of PGPR during the evolution. These associations are results of crosstalk through signaling cascade of various PGPR colonized on same plant surfaces. Plant Growth-Promoting Rhizobacteria. Plant growth-promoting rhizobacteria are the rhizosphere bacteria, which can ameliorate plant growth. These microorganisms are able to enhance the recycling of plant nutrients and decrease the use of chemical fertilization (Cakmakci et al., ). Hence these bacteria can be used as promising biofertilizers in organic farming .
