Drought is a major abiotic stress factor affecting plant growth and production, while utilizing beneficial endophytic fungi one of the most promising strategies for enhancing drought tolerance. In current study, pot experiment was conducted to investigate effects dark septate endophyte (DSE) (Macrophomina pseudophaseolina, Paraphoma radicina) Trichoderma (Trichoderma afroharzianum, longibrachiatum) inoculum on Astragalus mongholicus grown in sterile soil under stress, alone, or combination. The addition enhanced DSE colonization roots regardless water condition. Under well-watered conditions, M. pseudophaseolina inoculation significantly biomass root length A. mongholicus. two improved calycosin-7-O-β-D-glucoside content. However, + T. afroharzianum better promoted growth, whereas co-inoculation had higher active ingredient contents compared with single inoculation, except P. radicina afroharzianum. biomass, length, content, activities nitrate reductase urease. longibrachiatum increased all combinations greater impact increase formononetin content treatments.

This study mainly aimed to investigate the effects of dark septate endophytes (DSE) (Acrocalymma vagum, Paraboeremia putaminum and Fusarium acuminatum) on growth microbial community composition in rhizosphere soil a medicinal plant, liquorice (Glycyrrhiza uralensis), grown non-sterile under drought stress. The results showed that three DSE strains could effectively colonize plant roots formed strain-dependent symbiosis with liquorice. Although stress declined plants, these decreases were partly recovered by inoculation. Specifically, inoculation A.vagum P. significantly increased biomass glycyrrhizin content, whereas A. vagum F. acuminatum glycyrrhizic acid content host plants However, negatively shoot, root total plants.

Although the ecological function of dark septate endophytes (DSEs) is well studied, little known about responses host plant to DSEs obtained from other plants, especially under conditions heavy metal stress. This study aimed investigate how a heavy-metal habitat affect non-host plants in cadmium (Cd) stress soils, which then provides basis for application cultivation different and soil remediation strategies polluted ecosystems. We isolated identified two species DSE (Acrocalymma vagum Scytalidium lignicola) inhabiting roots Ilex chinensis (host plant) are grown metal-polluted habitats. Then, Cd tolerance was tested using pure culture concentration has been adjusted. Subsequently, we examined performance (Medicago sativa Ammopiptanthus mongolicus) were inoculated with growth chamber. The results indicated that could grow vitro, even when not exhibiting high levels Cd. superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH), soluble protein, melanin fungi reached maximal at concentrations 30-60 mg Cd/L, indicating important preventive adopted by environments contaminated Despite decreased biomass hyphae enhanced concentrations, accumulation tended show an increasing trend.

In particular, improved tissues stress, demonstrating potential bio-remediation heavy-metal-pollution areas.

Drought is one most devastating for cultivated crops, particularly in arid semiarid environments. Conventional breeding biotechnological approaches used generate drought-tolerant crop plants. However, these techniques costly time-consuming.
