Plant Growth Promoting Rhizobacteria (PGPR): Current and Future Prospects for Development of Sustainable Agriculture

Abstract

Soil is dynamic living matrix and it is not only a critical resource in agricultural and food security but it is also towards maintenance of all life process. Pathogenic microorganisms affecting plant health are a major and chronic threat to sustainable agriculture and ecosystem stability worldwide. The chemical fertilizers used in the agriculture to increase yields, kill pathogens, pests, and weeds, have a big harmful impact on the ecosystem. Because of current public concerns about the side effects of agrochemicals, there is an increasing interest in improving the understanding of cooperative activities among plants and rhizosphere microbial populations. So, there is an urgent need of biological agents is accepted worldwide. The use of plant growth promoting Rhizobacteria (PGPR) is a better alternative to solve this problem. They play an important role to increase in soil fertility, plant growth promotion, and suppression of phytopathogens for development of ecofriendly sustainable agriculture. This review provides environment friendly approach to increase crop production and health, development of sustainable agriculture and commercialization by using of plant growth promoting rhizobacteria with global applicability.

Isolation, Identification, Biochemical and Antibiotic Sensitivity Characterization of Rhizobium Strains from Vigna mungo (L) Hepper, Cicer arietinum L and Vigna radiata (L) R Wilczek in Muzaffarnagar, Uttar Pradesh, India

“…There is one more beneficial aspect of exploitation of Rhizobium in agricultural practice that the excessive use of chemicals to control plant diseases lead to groundwater contamination, development of resistant races of pathogen, human health hazardous and environmental detrimental (Akhar et al, 2009) and this shift the attention towards the plant growth-promoting Rhizobacteria (PGPR) which in recent years proved to be an alternative to chemicals by controlling the plant diseases effectively especially the soil and seed-borne pathogens (Beneduz et al, 2012, Gupta et al, 2015.…”

Prospection of Plant Growth-promoting Rhizobacterium Enterobacter cloacae and N2-fixing Rhizobium leguminosarum bv. viciae Effect on Faba Bean Evolution in Sustainable Agriculture

“…The addition of faba bean in cropping systems improves soil fertility by Rhizobium bacteria which concomitant biological nitrogen fixation (BNF), increased soil biological activity and reduced the need for fertilizer input in arable lands [6]. Plant growthpromoting rhizobacteria (PGPR) able to stimulate plant growth through enrichment of BNF, production of growth regulators soil nutrient solubilization (as P and K) [7] and improving nutrient uptake [8,9]. PGPR facilate the nutrient uptake through phytohormone production (e.g., auxin, cytokinin and gibberellins), enzymatic lowering of plant ethylene levels and/or production of siderophores [10,11,12,13].…”

Mechanistic insights on plant root colonization by bacterial endophytes: a symbiotic relationship for sustainable agriculture

“…The root exudates may antagonize one organism while attracting another, or two unrelated organisms may migrate towards roots with varying consequences. Different permutation of organisms residing in the rhizosphere as root-root, root-microbe, and root-insect interactions may be designated as either beneficial or detrimental based on their positive or negative effects posed on the plant or the microbe (Gupta et al 2015). Microorganisms which support and positively influence the plant growth upon colonizing roots or rhizosphere are called as plant growth promoting microorganisms (PGPM) (Kloepper et al 1980).…”
