The utilization of microbial inoculants in the realm of sustainable agricultural and ecosystem restoration has witnessed a surge in recent decades. This rise is largely attributed to advancements in our understanding of plant-microbe interactions, the urgency to reduce the dependence on agrochemicals and the growing societal demand for sustainable strategies in ecosystem management. However, despite the rapid growth of bio-inoculants sector, certain limitations persist concerning their efficacy and performance under the field condition. Here, we propose that seed biopriming, an effective microbial inoculant technique integrating both biological agents (the priming of beneficial microbes on seeds) and physiological aspects (hydration of seeds for improved metabolically activity), has a significant potential to mitigate these limitations. This method increases the protection of seeds against soil-borne pathogens and soil pollutants, such as salts and heavy metals, while promoting germination rate and uniformity, leading to overall improved primary productivity and soil health. Furthermore, we argue that a microbial coating on seeds can facilitate transgenerational associations of beneficial microbes, refine plant and soil microbiomes, and maintain soil legacies of beneficial microflora. This review article aims to improve our understanding of the seed biopriming approach as a potent and valuable tool in achieving sustainable agriculture and successful ecosystem restoration.
近年来，微生物接种剂在可持续农业和生态系统恢复领域的应用得到了迅猛发展。这种增长在很大程度上归因于我们对植物-微生物相互作用的理解的提高，减少对农用化学品依赖的紧迫性以及社会对生态系统管理中可持续战略的日益增长的需求。然而，尽管生物接种剂行业发展迅速，但在田间条件下，其功效和性能仍存在一定的局限性。在这里，我们提出，种子生物引发作为一种有效的微生物接种剂技术，它整合了生物制剂（在种子上引发有益微生物）和生理方面（种子的水合作用以提高代谢活性），具有减轻这些限制的巨大潜力。这种方法增加了种子对土壤传播病原体和土壤污染物（如盐和重金属）的保护，同时促进了发芽率和均匀性，从而提高了初级生产力和土壤健康的整体水平。此外，我们认为种子上的微生物涂层可以促进有益微生物的代际关联，改善植物和土壤微生物组，并保持有益微生物菌群的土壤遗传。这篇综述文章旨在提高我们对种子生物引发方法的理解，将其作为实现可持续农业和成功生态系统恢复的一种有力而有价值的工具。
