“…treated plant. Several other bacteria that are known to promote plant growth in presence of Cd have PGPR characteristics such as production of auxins, ACC deaminase or siderophores, which are the implicated mechanisms that contribute to the improved growth in presence of Cd stress in their host plants (Belimov and Dietz 2000;Dell'Amico et al 2008;Pishchik et al 2002;Safronova et al 2006;Sinha and Mukherjee 2008). In the present case, the role of organic acid secretion by E. asburiae PSI3 in imparting Cd tolerance to mung bean plants was explored by exogenous application of pure organic acids to seedlings cultivated under hydroponics.…”

Mung bean seedlings inoculated withEnterobacter asburiae PSI3, a gluconic acid-producing rhizosphere isolate, enhanced plant growth in the presence of phytotoxic levels of Cd 2? in gnotobiotic pot experiments as compared to the uninoculated Cd-treated plants. Addition of organic acids to Cd-stressed seedlings promoted root elongation. Hematoxylin competition assays showed that organic acids could displace Cd 2? from the Cd 2? : hematoxylin complex in the same order of effectiveness as was found for restoration of root net elongation viz. oxalate [ malate [ succinate while gluconate was effective at higher concentrations. Root associated Cd 2? , assessed by hematoxylin staining of roots was found to be reduced when roots were treated with organic acid. Cd stress increased antioxidant enzymes such as peroxidase and superoxide dismutase in mung bean roots while organic acid treatment suppressed the up-regulation of these enzymes by Cd.

“…The PGPR mechanisms in plant towards abiotic stress were previously studied extensively. Pishchik et al [25] reported that PGPR could be attenuated by the toxic effect of cadmium pollution on barley plants due to the ability of the bacteria to cadmium ions from the soil by binding mechanisms, thereby decreasing the availability of cadmium in the soil.…”

Role of Plant Growth Promoting Rhizobacteria in Agricultural Sustainability—A Review

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 nowadays. The use of PGPR has been proven to be an environmentally sound way of increasing crop yields by facilitating plant growth through either a direct or indirect mechanism. The mechanisms of PGPR include regulating hormonal and nutritional balance, inducing resistance against plant pathogens, and solubilizing nutrients for easy uptake by plants. In addition, PGPR show synergistic and antagonistic interactions with microorganisms within the rhizosphere and beyond in bulk soil, which indirectly boosts plant growth rate. There are many bacteria species that act as PGPR, described in the literature as successful for improving plant growth. However, there is a gap between the mode of action (mechanism) of the PGPR for plant growth and the role of the PGPR as biofertilizer-thus the importance of nano-encapsulation technology in improving the efficacy of PGPR. Hence, this review bridges the gap mentioned and summarizes the mechanism of PGPR as a biofertilizer for agricultural sustainability.

“…Furthermore, OTU975 ( Bryobacter ), OTU3504 ( Flavobacterium ), OTU3634 ( Cytophaga ), and OTU4956 ( Flavisolibacter ) indicated higher relative abundances in Si200 than Si0 ( Supplementary Table 4 ). The higher abundances of Flavobacterium may increase sugarcane growth, improve soil AP and AK, inhibit plant pathogens, and produce large quantities of indole-3-acetic acid (IAA) for the promotion of plant growth (Pishchik et al, 2002 ; Meena et al, 2015 ; Vijayabharathi et al, 2016 ; Cardoso et al, 2018 ). Many studies reported that Bryobacter are PGPR, and could use organic acids, polysaccharides, and various sugars to participate in the biogeochemical carbon cycle (Dedysh et al, 2017 ; Liu et al, 2019 ).…”

Silicon (Si) deficiency, caused by acidic soil and rainy climate, is a major constraint for sugarcane production in southern China. Si application generally improves sugarcane growth; however, there are few studies on the relationships between enhanced plant growth, changes in rhizosphere soil, and bacterial communities. A field experiment was conducted to measure sugarcane agronomic traits, plant nutrient contents, rhizosphere soil enzyme activities and chemical properties, and the rhizosphere bacterial community diversity and structure of three predominant sugarcane varieties under two Si treatments, i.e., 0 and 200 kg of silicon dioxide (SiO2) ha−1 regarded as Si0 and Si200, respectively. Results showed that Si application substantially improved the sugarcane stalk fresh weight and Si, phosphorus (P), and potassium (K) contents comparing to Si0, and had an obvious impact on rhizosphere soil pH, available Si (ASi), available P (AP), available K (AK), total phosphorus (TP), and the activity of acid phosphatase. Furthermore, the relative abundances of Proteobacteria showed a remarkable increase in Si200, which may be the dominant group in sugarcane growth under Si application. Interestingly, the AP was noticed as a major factor that caused bacterial community structure differences between the two Si treatments according to canonical correspondence analysis (CCA). In addition, the association network analysis indicated that Si application enriched the rhizosphere bacterial network, which could be beneficial to sugarcane growth. Overall, appropriate Si application, i.e., 200 kg SiO2 ha−1 promoted sugarcane growth, changed rhizosphere soil enzyme activities and chemical properties, and bacterial community structures.
