Plant microbiomes represent dynamic entities, influenced by the environmental stimuli and stresses in the surrounding conditions. Studies have suggested the benefits of commensal microbes in improving the overall fitness of plants, besides beneficial effects on plant adaptability and survival in challenging environmental conditions. The concept of 'Defense biome' has been proposed to include the plant-associated microbes that increase in response to plant stress and which need to be further explored for their role in plant fitness. Plant-associated endophytes are the emerging candidates, playing a pivotal role in plant growth, adaptability to challenging environmental conditions, and productivity, as well as showing tolerance to biotic and abiotic stresses. In this article, efforts have been made to discuss and understand the implications of stress-induced changes in plant endophytic microbiome, providing key insights into the effects of heavy metals on plant endophytic dynamics and how these beneficial microbes provide a prospective solution in the tolerance and mitigation of heavy metal in contaminated sites.
植物微生物群落是动态实体，受周围环境刺激和压力的影响。研究表明，共生微生物除了对植物在具有挑战性的环境条件下的适应性和生存有益外，还对提高植物的整体健康状况有益。“防御生物群落”的概念已被提出，其中包括因植物应激而增加的与植物相关的微生物，其在植物健康方面的作用有待进一步探索。与植物相关的内生菌是新兴的候选对象，它们在植物生长、对具有挑战性的环境条件的适应性和生产力方面发挥着关键作用，同时也表现出对生物和非生物胁迫的耐受性。在本文中，我们努力探讨和理解植物内生微生物群落应激诱导变化的影响，深入了解重金属对植物内生动态的影响，以及这些有益微生物如何为受污染场地中重金属的耐受性和缓解提供前瞻性解决方案。
