The plant immune system inhibits pathogen growth and contributes to shaping a healthy microbial community in the plant body. Plants must appropriately respond to both microbial signals and abiotic factors that are diverse in time and space, and thus, proper integration of these inputs at local and systemic levels is of crucial importance for optimal plant responses and fitness in nature. Here, we review our current knowledge of three properties of the plant immune system, resilience, tunability, and balance, which enable plants to deal with complex cocktails of environmental factors. We also discuss future challenges on the path towards a comprehensive understanding of the interactions between plant immunity and pathogenic, non-pathogenic, and beneficial microbes.
植物免疫系统抑制病原体生长，并有助于在植物体内形成健康的微生物群落。植物必须对微生物信号和时空上多样化的非生物因素做出适当的反应，因此，在局部和系统水平上适当整合这些输入对于植物在自然界中的最佳反应和适应性至关重要。在这里，我们回顾了植物免疫系统的三个特性——弹性、可调节性和平衡性，这些特性使植物能够应对复杂的环境因素组合。我们还讨论了在全面理解植物免疫与病原性、非病原性和有益微生物相互作用的道路上未来的挑战。
