A pot experiment was conducted to investigate the potential influence of arbuscular mycorrhizal fungi (AMF), Funneliformis mosseae and Diversispora spurcum, on growth nutrient (P S) heavy metal (HMs) (Pb, Zn, Cd) content bermudagrass [Cynodon dactylon (L.) Pers.] in a lead-zinc mine wasteland. The D. spurcum inoculation significantly increased growth, whereas F. did not. AMF soil pH uptake P, S, HMs by bermudagrass, decreased contents available Pb Zn soils shoots, reduced translocation...

Arbuscular mycorrhizal fungi (AMF) exist widely in soil polluted by heavy metals and have significant effects on plant growth cadmium (Cd) uptake. Cd contents differ among wasteland, farmland slopeland soils a lead-zinc mining area Yunnan Province, Southwest China. The of AMF maize growth, root morphology, low-molecular-weight organic acid (LMWOA) concentrations uptake were investigated via root-bag experiment. results show that increased Cd-polluted soils, resulting increases length,...

A field experiment in which a hyperaccumulator (Arabis alpina) was intercropped with winter crop (Vicia faba), conducted to understand effect of the root exudates on content and accumulated amounts, sub-cellular distribution Cd Pb plants during ripening period V. faba (120 d after sowing). The results showed that contents soluble sugars exuded from roots A. alpina were 67.6% less than monocropped plant, whereas free amino acids 57.9% greater. total organic 578.8% 37.8% greater plants,...

Arbuscular mycorrhizal fungi (AMF) and dark septate endophytes (DSE) are generally colonized in plant roots metal-polluted environment. A pot experiment including four treatments (AMF inoculation of Funneliformis mosseae, DSE Exophiala pisciphila, co-inoculation AMF + DSE, non-inoculation) under a high cadmium (Cd) stress (50 mg/kg) was conducted to discuss the ecological functions interactions DSE. The biomass, photosynthetic physiology, root morphology traits, Cd content maize were...

The ecological role of arbuscular mycorrhizal fungi (AMF) on altering cadmium (Cd) migration in polluted soil is still unresolved. present experiment aimed to clarify whether AMF can reduce Cd loss due leaching at different concentrations (0, 5, 10, and 15 mg L−1) with maize as a host plant cultured sand column. effects the fungus Funneliformis mosseae root morphology, exudate content, uptake by were investigated. altered morphology content maize, resulting increases length, volume, surface...

Dark septate endophytes (DSE) are typical root with the ability to enhance plant growth and tolerance heavy metals, but underlying mechanisms unclear. Here, physiological molecular of a DSE strain, Exophiala pisciphila, in mitigating cadmium (Cd, 20 mg/kg) toxicity maize were investigated. Our results showed, under Cd stress, E. pisciphila inoculation enhanced biomass reduced both inorganic soluble forms (high toxicity) by 52.6% leaves, which may be potentially contributing mitigation....

The soil in a lead–zinc mining area, contaminated with heavy metals like cadmium (Cd) and lead (Pb), poses risk to crops such as maize. Experiments using biochar sepiolite ameliorants potted maize showed these substances can mitigate metal contamination. Biochar increased potassium phosphorus the maize, while significantly boosted overground by 73.2%. Both transformed Cd Pb into more stable state soil, reducing their accumulation especially biochar, which effectively inhibited migration...

Intercropping reduced the crop Cd contents and enhanced remediation, which was related to roots LMWOAs exudation in soils.

A high Cd-tolerant dark septate endophyte (DSE), Exophiala pisciphila, was inoculated into maize (Zea mays L.) roots under Cd stress. The content, enzymes activity and thiol compound content relevant to glutathione (GSH) metabolism in leaves were analyzed. shoots increased with increasing stress, but the DSE significantly reduced at 40 mg/kg treatment. stress enzyme of reductase (GR), S-transferase (GST) peroxidase (GSH-Px) as well contents sulfur, thiols (-SH) oxidized (GSSG). GSH GSH/GSSG...

This paper aims to investigate the mechanism by which dark septate endophytes (DSEs) enhance cadmium (Cd) tolerance in there host plants. Maize (Zea mays L.) was inoculated with a DSE, Exophiala pisciphila, under Cd stress at different concentrations (0, 5, 10, and 20 mg·kg-1). The results show that, mg/kg stress, DSE significantly increased maize biomass plant height, indicating that colonization can be utilized increase of More retained DSE-inoculated roots, especially fixed root cell wall...

Dark septate endophytes (DSEs) can improve the performance of host plants grown in heavy metal-polluted soils, but mechanism is still unclear. A sand culture experiment was performed to investigate effects a DSE strain (Exophiala pisciphila) on maize growth, root morphology, and cadmium (Cd) uptake under Cd stress at different concentrations (0, 5, 10, 20 mg·kg−1). The results indicated that significantly improved tolerance maize, causing increases biomass, plant height, morphology (length,...

Introduction Arbuscular mycorrhizal fungi (AMF) and dark septate endophytic (DSEs) generally coexist in the roots of plants. However, our understanding effects their coexistence on plant growth stress resistance is limited. Methods In present study, single dual inoculation AMF DSE growth, photosynthetic physiology, glutathione (GSH) metabolism, endogenous hormones, cadmium (Cd) content maize under 25 mg•kg -1 Cd were investigated. Results Compared with that after non-inoculation treatment,...

Li doping enhanced the ability of nano-MgO to adsorb oxygen and generate ROS, further improving its antibacterial performance.

The soil and water conservation capacity of forest ecosystems is closely associated with precipitation, runoff, sediment delivery, the export nutrients nitrogen (N) phosphorus (P) from soil. Research has investigated potential for decreasing runoff pollution watersheds by improving function in conserving water. Four typical ecological systems, including <i>Pinus armandii</i> forest, Yunnan pine mixed broadleaf-conifer broad-leaved were compared vegetation community structure species...
