The modern agricultural system has issues with the reduction of agricultural productivity due to a wide range of abiotic and biotic stresses. It is also expected that in the future the entire world population may rapidly increase and will surely demand more food. Farmers now utilize a massive quantity of synthetic fertilizers and pesticides for disease management and to increase food production. These synthetic fertilizers badly affect the environment, the texture of the soil, plant productivity, and human health. However, agricultural safety and sustainability depend on an ecofriendly and inexpensive biological application. In contrast to synthetic fertilizers, soil inoculation with plant-growth-promoting rhizobacteria (PGPR) is one of the excellent alternative options. In this regard, we focused on the best PGPR genera, , which exists in the rhizosphere as well as inside the plant's body and plays a role in sustainable agriculture. Many spp. control plant pathogens and play an effective role in disease management through direct and indirect mechanisms. spp. fix the amount of atmospheric nitrogen, solubilize phosphorus and potassium, and also produce phytohormones, lytic enzymes, volatile organic compounds, antibiotics, and secondary metabolites during stress conditions. These compounds stimulate plant growth by inducing systemic resistance and by inhibiting the growth of pathogens. Furthermore, pseudomonads also protect plants during different stress conditions like heavy metal pollution, osmosis, temperature, oxidative stress, etc. Now, several -based commercial biological control products have been promoted and marketed, but there are a few limitations that hinder the development of this technology for extensive usage in agricultural systems. The variability among the members of spp. draws attention to the huge research interest in this genus. There is a need to explore the potential of native spp. as biocontrol agents and to use them in biopesticide development to support sustainable agriculture.
现代农业系统存在诸多问题，由于各种非生物和生物胁迫，农业生产力有所下降。预计未来全球人口将迅速增长，肯定会需要更多食物。农民现在使用大量合成肥料和农药来进行病害管理并增加粮食产量。这些合成肥料严重影响环境、土壤质地、植物生产力和人类健康。然而，农业安全和可持续性依赖于生态友好且成本低廉的生物应用。与合成肥料相比，用促植物生长根际细菌（PGPR）接种土壤是极佳的替代选择之一。在这方面，我们聚焦于最佳的PGPR属，其存在于根际以及植物体内，在可持续农业中发挥作用。许多[具体属名]种控制植物病原体，并通过直接和间接机制在病害管理中发挥有效作用。[具体属名]种固定大气中的氮含量，溶解磷和钾，并且在胁迫条件下还产生植物激素、裂解酶、挥发性有机化合物、抗生素和次生代谢产物。这些化合物通过诱导系统抗性和抑制病原体生长来刺激植物生长。此外，假单胞菌在诸如重金属污染、渗透、温度、氧化应激等不同胁迫条件下也能保护植物。现在，已有几种基于[具体属名]的商业生物防治产品得到推广和销售，但存在一些限制因素阻碍了该技术在农业系统中的广泛应用。[具体属名]种成员之间的变异性引起了对该属的巨大研究兴趣。有必要探索本地[具体属名]种作为生物防治剂的潜力，并将它们用于生物农药开发以支持可持续农业。
