Dark septate endophytes (DSE) exert a plethora of effects in regulating plant growth, signalling and stress tolerance. The advent of metagenomics has led to the identification of various species of DSE to be associated with plant organs. They are known to modulate growth, nutrient uptake, phytohormone biosynthesis and production of active bioconstituents in several plants. The interactions between the DSE and host plants are mostly mutualistic but they can also be neutral or exhibit negative interactions. The DSE has beneficial role in removal/sequestration of toxic heavy metals from various environmental sites. Here, we discuss the beneficial role of DSE in enhancing plant tolerance to heavy metal stress, drought conditions, high salinity and protection from various plant pathogens. Furthermore, the underlying mechanism of stress resilience facilitated by DSE-plant interaction has also been discussed. The article also provides insights to some important future perspectives associated with DSE-mediated phytoremediation and reclamation of polluted land worldwide thus facilitating sustainable agriculture.
深色有隔内生真菌（DSE）在调节植物生长、信号传递和抗逆性方面发挥着多种作用。宏基因组学的出现导致了各种与植物器官相关的 DSE 物种的鉴定。它们被认为可以调节多种植物的生长、养分吸收、植物激素生物合成和活性生物成分的产生。DSE 与宿主植物之间的相互作用大多是互利的，但也可以是中性的，也可以表现出负相互作用。DSE 在从各种环境场所去除/隔离有毒重金属方面具有有益作用。在这里，我们讨论了 DSE 增强植物对重金属胁迫、干旱条件、高盐度和各种植物病原体的耐受性的有益作用。此外，还讨论了 DSE-植物相互作用促进的应激弹性的潜在机制。本文还为与 DSE 介导的植物修复和全球受污染土地的开垦相关的一些重要未来展望提供了见解，从而促进了可持续农业。
