Agricultural plants are continuously exposed to environmental stressors, which can lead to a significant reduction in yield and even the death of plants. One of the ways to mitigate stress impacts is the inoculation of plant growth-promoting rhizobacteria (PGPR), including bacteria from the genus , into the rhizosphere of plants. Different representatives of this genus have different sensitivities or resistances to osmotic stress, pesticides, heavy metals, hydrocarbons, and perchlorate and also have the ability to mitigate the consequences of such stresses for plants. Bacteria from the genus contribute to the bioremediation of polluted soils and induce systemic resistance and have a positive effect on plants under stress by synthesizing siderophores and polysaccharides and modulating the levels of phytohormones, osmolytes, and volatile organic compounds in plants, as well as altering the efficiency of photosynthesis and the antioxidant defense system. In this review, we focus on molecular genetic features that provide bacterial resistance to various stress factors as well as on -related pathways for increasing plant resistance to unfavorable anthropogenic and natural factors.
农业植物不断暴露在环境胁迫下，这可能导致产量显著下降，甚至植物死亡。减轻胁迫影响的方法之一是将植物促生根际细菌（PGPR），包括属中的细菌，接种到植物的根际中。该属的不同代表对渗透胁迫、农药、重金属、碳氢化合物、高氯酸盐的敏感性或抗性不同，并且具有减轻这些胁迫对植物后果的能力。属中的细菌有助于污染土壤的生物修复，并通过合成铁载体和多糖诱导系统抗性，并通过调节植物中植物激素、渗透物和挥发性有机化合物的水平以及改变光合作用和抗氧化防御系统的效率，对胁迫下的植物产生积极影响。在这篇综述中，我们重点介绍了赋予细菌对各种应激因素抗性的分子遗传特征，以及与提高植物对不利人为和自然因素抗性相关的途径。
