Numerous microbial communities show synergistic and antagonistic interactions among themselves, resulting in benefit and harm to either or both the associated members. The association holds accountability for nutrients recycling and energy drift, resulting in the availability of macronutrients unavailable and insoluble forms of rhizospheric nutrients, crucial for vital processes in plants, e.g., act as co-factors of various phyto-enzyme and redox mediators. Plant growth promoting rhizobacteria are known to enhance plant growth by increasing these macronutrients availability during their plant root colonization. In comparison to any other genera, is the most favored bioinoculant due to its significant properties in both plant growth and phytopathogen control during its synergistic association with the host plant. These properties include siderophore production, phosphate solubilization, nitrogen fixation, phenazines, antibiotics, and induced systemic resistance carried out by various species like and . The association of with crop plants procures several secretory and electron-based feedback mechanisms in order to regulate the plant growth and phytopathogen control activities through the secretion of several phytohormones (auxins, gibberellins, Indole-3-acetic acid), secondary metabolites (flavonoids) and enzymes (aminocyclopropane-1-carboxylate, phenylalanine ammonia-lyase). Ecologically significant applications of Pseudomonas in biocontrol and bioaugmentation are crucial for maintaining food security.
众多微生物群落之间存在协同和拮抗相互作用，对相关成员一方或双方产生益处或危害。这种关联对养分循环和能量流动负有责任，使得根际养分中不可用和不溶性的大量养分得以利用，这些养分对植物的重要过程至关重要，例如作为各种植物酶和氧化还原介质的辅助因子。已知植物促生根际细菌在定殖于植物根系期间，通过增加这些大量养分的可用性来促进植物生长。与其他任何属相比，由于其在与宿主植物协同关联期间在植物生长和植物病原体控制方面具有显著特性，因此是最受欢迎的生物接种剂。这些特性包括铁载体的产生、磷的溶解、固氮、吩嗪、抗生素以及由诸如和等各种物种进行的诱导系统抗性。与作物植物的关联产生了几种分泌型和基于电子的反馈机制，以便通过分泌几种植物激素（生长素、赤霉素、吲哚 - 3 - 乙酸）、次生代谢产物（类黄酮）和酶（氨基环丙烷 - 1 - 羧酸、苯丙氨酸解氨酶）来调节植物生长和植物病原体控制活动。假单胞菌在生物防治和生物强化方面具有重要的生态学应用，对维持粮食安全至关重要。
