“…The positive relationships between the effect size of total biomass and the effect sizes of N, P, and K + uptake in both SSP and STP support findings that PGPR can aid in the resumption of plant growth by retaining the nutrient acquisition of plants [3] ( Figure 6) as PGPR could: (1) increase the nutrient availability by altering the root structure and root exudates and accelerating the nutrient cycling [56];…”

Understanding the primary mechanisms for plant promotion under salt stress with plant growth promoting rhizobacteria (PGPR) inoculation of different salt-tolerant plant groups would be conducive to using PGPR efficiently. We conducted a meta-analysis to evaluate plant growth promotion and uncover its underlying mechanisms in salt-sensitive plants (SSP) and salt-tolerant plants (STP) with PGPR inoculation under salt stress. PGPR inoculation decreased proline, sodium ion (Na+) and malondialdehyde but increased plant biomass, nutrient acquisition (nitrogen, phosphorus, potassium ion (K+), calcium ion (Ca2+), and magnesium ion (Mg2+)), ion homeostasis (K+/Na+ ratio, Ca2+/Na+ ratio, and Mg2+/Na+ ratio), osmolytes accumulation (soluble sugar and soluble protein), antioxidants (superoxide dismutase), and photosynthesis (chlorophyll, carotenoid, and photosynthetic rate) in both SSP and STP. The effect size of total biomass positively correlated with the effect sizes of nutrient acquisition and the homeostasis of K+/Na+, and negatively correlated with the effect size of malondialdehyde in both SSP and STP. The effect size of total biomass also positively correlated with the effect sizes of carotenoid and the homeostasis in Ca2+/Na+ and Mg2+/Na+ and negatively correlated with the effect size of Na+ in SSP, but it only negatively correlated with the effect size of Ca2+ in STP. Our results suggest that the plant growth improvement depends on the nutrient acquisition enhancement in both SSP and STP, while ion homeostasis plays an important role and carotenoid may promote plant growth through protecting photosynthesis, reducing oxidative damage and promoting nutrient acquisition only in SSP after PGPR inoculation under salt stress.

“…When plant growth suppression is the result of ethylene stress, PGPR with ACCD can be exploited [27]. ACCD metabolizes ACC, a precursor of ethylene in the biosynthesis pathway, thus limiting the amount of ethylene stress that can be produced [28,29]. Polyamines secreted by PGPR have also been exposed to mitigate stress ethylene levels and alleviate osmotic stress [30,31].…”

“…Polyamines secreted by PGPR have also been exposed to mitigate stress ethylene levels and alleviate osmotic stress [30,31]. PGPR have been demonstrated to activate the synthesis of antioxidants and indole acetic acid, which can stimulate root growth [28,32,33]. Recently, PGPR were shown to alter mineral uptake, which results in a favorable increase in the cellular ratio of K+/Na+; and elevated generation of quorum-sensing molecules, which can lead to modifications in the rhizosphere [34][35][36].…”

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.
