endophytes and arbuscular mycorrhizal fungi (AMFs) are two important symbiotic microorganisms of tall fescue (). Our research explores the combined effects of endophytes and AMF on saline-alkali stress. The finding revealed that a significant interaction between endophytes and AMF, and saline-alkali stress occurred in the growth and physiological parameters of tall fescue. Endophyte infection significantly enhanced tall fescue resistance to saline-alkali stress by increasing shoot and root biomass and nutrient uptake (organic carbon, total nitrogen, and total phosphorus concentration), and accumulating K while decreasing Na concentration. Furthermore, the beneficial effect of endophytes was enhanced by the beneficial AMF, (CE) but was reduced by the detrimental AMF, (FM). Our findings highlight the importance of interactions among multiple microorganisms for plant performance under saline-alkali stress.
内生菌和丛枝菌根真菌（AMF）是高羊茅两种重要的共生微生物。我们的研究探讨了内生菌和AMF对盐碱胁迫的综合影响。研究结果表明，内生菌与AMF之间以及盐碱胁迫对高羊茅的生长和生理参数存在显著的相互作用。内生菌感染通过增加地上部和根部生物量以及养分吸收（有机碳、总氮和总磷浓度），并积累钾同时降低钠浓度，显著增强了高羊茅对盐碱胁迫的抗性。此外，有益的AMF增强了内生菌的有益作用（CE），但有害的AMF（FM）则降低了这种作用。我们的研究结果突出了多种微生物之间的相互作用对盐碱胁迫下植物性能的重要性。
