Due to climate change, the quality of the agricultural soils is decreasing, and some human activities make this situation worse. In this context, crops struggle to grow due to the presence of abiotic stresses such as salinity, organic and inorganic pollution, drought, and high temperatures, which interfere with their development, causing a loss of productivity. As the world population is increasing, it is important to promote crop growth, even in degraded soils with the presence of abiotic stress, to feed the population. To stop the reduction in agricultural areas due to human activities, it is necessary to change the way of promoting crop growth, replacing chemical fertilizers and pesticides with more ecofriendly tools.
In both of the cases discussed above, plant-growth-promoting bacteria (PGPB) are excellent candidates to improve crop development and productivity in order to promote their growth in degraded soils and alleviate plant stress. In addition, PGPB have plant-growth-promoting (PGP) properties, which help plants to uptake nutrients and protect against biotic stresses such as phytopathogens. For this reason, PGPB have the potential to be used as biofertilizers and biopesticides for crop improvement in any environment in sustainable agriculture.

Abstract: In recent decades, the increasing incidences of abiotic and biotic stresses in plants have been a major cause of decrease in crop yield. Abiotic stress including solar radiation, extreme temperature variations, drought, soil salinity, flooding, and heavy metals, etc. have greatly impacted crop yield. Similarly, the biotic stress imposed on plants by several phytopathogens including viruses, bacteria, fungi, oomycetes, nematodes, and arthropods has become a threat to the growth and development of plants. Presently, these stresses have become an important topic of discussion in both basic and applied fields of botany, agriculture, ecology, and environmental studies. Plants have developed various mechanisms for coping with these stresses. Particularly the interaction or using of new engineered nanomaterials in agriculture that alleviating and resilience of stresses has been an important discovery on sustaining plant growth under stress conditions. Plant signaling coupled with stimulation of cellular responses by particles interaction has been an intricate component of stress management principles. Other side, these nanomaterials - microflora interact with the plant either as endophytes or epiphytes residing in the rhizosphere or phyllosphere. Interestingly, the development of multi-omics technologies and high-performance platforms integrating genomic, transcriptomics, proteomics, and metabolomics data have made several advancements in deciphering the plant-microbial- nanomaterials interaction and their role played in stress management. Further, the advancements in policy changes, delivery of technology, application of sensors, product formulations, nanofertilizers, genetic transformation and priming, etc. have become important areas of research for stress management of cropping plants on a global scale. In this review, an attempt has been made to shed light on the intricate stress abatement mechanisms delivered by bacteria in plants and available technologies mitigating stress responses, integrating which a holistic approach towards multiple stress management issues in plants could be developed for sustaining crop output.
