“…The photosynthetic machinery in plants is very sensitive to environmental stresses [ 17 , 95 ]. However, exogenous application of Si enhanced the photosynthetic capacity in various plants subjected to abiotic stresses [ 2 , 17 , 29 , 46 , 96 , 97 ]. Silicon enhanced photosynthesis, nutrient uptake, and ultimately plant growth development and biomass subjected to various stresses through increasing leaf gas exchange.…”

“…Water deficit impairs nutrient availability and its uptake in the rhizosphere. Further, impaired nutrient translocation downregulates metabolic activities linked with growth and development [ 17 , 108 ]. Exogenous application of Si may balance the uptake and mobility of minerals in plants suffering from environmental stresses [ 20 ].…”

“…The application of Si may mitigate oxidative damage in plants by modulating the enzymatic and non-enzymatic constituents [ 39 , 126 ]. Generally, the negative impact of stress on plant metabolism leads to overproduction of ROS (e.g., singlet O 2 , hydroxyl radical, H 2 O 2 and superoxide anion), which impairs various metabolic functions, causing damage to proteins, lipids, carbohydrates, and DNA [ 17 , 20 ]. ROS, in turn, may also induce a damaging effect on the plasma membrane and endo-membrane systems, and disturb general metabolic processes.…”

“…Lots of experimental studies have demonstrated that Si affects water-associated plant processes, mainly during environmental stresses [ 17 , 20 , 39 ]. Salinity- and water-stressed plants have shown a loss in water uptake, while Si application upgrades the water level and water use efficiency (WUE) in various plant cultivars [ 50 , 128 , 129 ].…”

Abiotic stresses are the major constraints in agricultural crop production across the globe. The use of some plant–microbe interactions are established as an environment friendly way of enhancing crop productivity, and improving plant development and tolerance to abiotic stresses by direct or indirect mechanisms. Silicon (Si) can also stimulate plant growth and mitigate environmental stresses, and it is not detrimental to plants and is devoid of environmental contamination even if applied in excess quantity. In the present review, we elaborate the interactive application of Si and plant growth promoting rhizobacteria (PGPRs) as an ecologically sound practice to increase the plant growth rate in unfavorable situations, in the presence of abiotic stresses. Experiments investigating the combined use of Si and PGPRs on plants to cope with abiotic stresses can be helpful in the future for agricultural sustainability.
