Functioning of Plant Growth Promoting Rhizobacteria (Pgpr) and Their Mode of Actions: An Overview From Chemistry Point of View

Abstract: In one stage of mankind's struggle to keep pace with ever increasing demand of food due to accelerating world population, chemical fertilizers contributed enormously to produce sufficient food products. However, a stagnation in the crop productivity along with decreasing soil fertility status and environmental pollution due to continuous, excessive, and imbalanced use of chemical fertilizers. In this scenario, plant growth promoting rhizobacteria (PGPR) become a natural choice as an alternative to the fertiliz… Show more

“…Biological nitrogen fixation (BNF) refers to the process of converting nitrogen in the atmosphere into ammonia available to plants through the action of nitrogen-fixing microorganisms [46]. Common nitrogen-fixing microorganisms include Rhizobium spp., Acetobacter spp., Arthrobacter spp., Citrobacter spp., Clostridium spp., Streptomyces spp., and so on [47].…”

“…This cycle proceeds as increased root exudation leads to increased bacterial proliferation. However, it is also true that IAA production alone cannot explain a plant's ability to promote growth because it indirectly inhibits root elongation [64]. Khan et al [65] have determined that the excessive use of fungicides in agriculture can lead to a significant accumulation of active residues in the soil, resulting in negative impacts on crop health and yield.…”

“…For example, Plant Growth Promoting Rhizobacteria (PGPRs) are a group of rhizobacteria found in the plant rhizosphere that can promote plant growth through multiple modes of action (Ashrafuzzaman et al, 2009;Bhattacharyya and Jha, 2012;Gupta et al, 2015). The mode of action varies greatly between each PGPR, from secretion of plant hormones, secondary metabolites, volatile organic compounds, to manipulation of the abiotic environment (Vessey, 2003;Ahmed and Holmström, 2014;Kenawy et al, 2019;Riaz et al, 2021;Sukul et al, 2021). PGPRs can be developed into biofertilizers and biocontrol to support plant health and reduce the impacts of stresses.…”
