Endophytic fungi of medicinal plants are symbiotic with the host and play an important role in determining metabolites. To understand relationship between accumulation Sophora alopecuroides' bioactive compounds ecological succession endophytic fungi, here we collected samples from S. alopecuroides at four developmental stages (adult, flowering, podding, mature) different organs (roots, stems, leaves, seeds) mature stage. We then used high-performance liquid chromatography-mass spectrometry high-throughput sequencing on internal transcribed spacer region to identify fungal communities each sample.

Dark septate endophytes (DSEs) usually colonize plant roots, especially in stress environments. However, their relationship with plants ranges from beneficial to harmful and has remained largely uncharacterized. In the present study, 14 DSE species grouped into 11 genera were isolated roots of a desert plant, Artemisia ordosica, which is widely distributed northwest China. Three dominant species-Paraphoma chrysanthemicola (Pc), Alternaria chartarum (Ac), Acrocalymma vagum (Av)-were selected tested for resistance drought vitro. Furthermore, we characterized responses A. ordosica under conditions relation presence these DSEs following inoculation. The results showed that all three strains grew well vitro stress, biomass Ac Av was significantly higher than unstressed control. effects inoculation on growth varied according different but generally beneficial. Under Pc promoted growth, antioxidant enzyme activity, root development hosts. strain conferred obvious positive activity general, demonstrated better application potential improving ordosica.

Arid desert regions are among the harshest ecological environments on Earth. Halophytes, with their unique physiological characteristics and adaptability, have become dominant vegetation in these areas. Currently, research halophytes this region is relatively limited, particularly concerning studies related to root endophytic fungi, which been rarely reported on. Therefore, investigating diversity composition of fungi crucial for maintaining balance such an arid environment. This study focuses eight representative angiosperm from West Ordos Desert China (including Nitraria tangutorum, Salsola passerina, Suaeda glauca, Reaumuria trigyna, kaschgarica, Limonium aureum, Apocynum venetum, Tripolium vulgare), utilizing Illumina MiSeq high-throughput sequencing technology combined soil physicochemical factor data analyze diversity, composition, functions root-associated fungal communities. Ascomycota dominated most halophytes, recretohalophytes, where it accounted average 88.45%, while Basidiomycota was predominant glauca. A Circos analysis top 10 abundant genera revealed Fusarium, Dipodascus, Curvularia, Penicillium, other genera. Co-occurrence network showed significant differences networks across halophyte types, complex observed excreting characterized by highest number nodes connections, indicating tighter symbiotic relationships. In contrast, pseudohalophytes were simple, reflecting lower community cohesiveness. Redundancy (RDA) Mantel tests demonstrated that factors as organic matter, available sulfur, urease significantly influenced richness, evenness, suggesting properties play a critical role regulating fungal-plant symbiosis. Functional predictions indicated important roles metabolic pathways nucleotide biosynthesis, carbohydrate degradation, lipid metabolism, may enhance plant survival saline-alkaline environments. Furthermore, high abundance pathogens saprotrophs some communities suggests potential defense matter decomposition. The results provide reference advancing development utilization resources, applications ecosystem restoration cultivation.
