Abstract

Plants have microbial companions inhabiting a hidden world within their tissues that play relevant roles in their environmental fitness. Some of these beneficial microorganisms can colonize seeds by exerting a functional echo in future generations. In this study, we review the most recent advances in microbial endophytes residing in seeds and their ecological functions, including the reproductive stage, from germination to adulthood. Similar to free-living plant growth-promoting microorganisms, microbial endophytes, whether bacteria or fungi, exhibit similar direct (e.g., facilitation of resources and regulation of phytohormones) and indirect (e.g., antibiosis and induced systemic resistance) action mechanisms, which are also analyzed. Finally, some agro-biotechnological applications of microbial endophytes and their advantages of being inherited through seeds are discussed, such as facilitating their field application and ensuring that their beneficial actions increase crop health and sustainable production.

微生物种子内生菌在农业中的作用:机制与应用
植物组织内隐藏着许多微生物伙伴,它们在植物的环境适应性方面发挥着重要作用。其中一些有益微生物可以定殖在种子中,对后代产生功能性的影响。在本研究中,我们回顾了关于寄居在种子中的微生物内生菌及其生态功能的最新进展,包括从萌芽到成年的生殖阶段。与自由生活的植物生长促进微生物类似,微生物内生菌,无论是细菌还是真菌,都表现出类似的直接(如促进资源和调节植物激素)和间接(如抗生素和诱导系统抗性)作用机制,本文也对这些机制进行了分析。最后,还讨论了微生物内生菌的一些农业生物技术应用及其通过种子遗传的优势,如促进其田间应用,确保其有益作用提高作物健康和可持续生产。
