Under Cd stress, DSE inoculation significantly enhanced the activities of antioxidant enzymes and low-molecular weight antioxidants, while also inducing increased Cd accumulation in the cell wall and conversion of Cd into inactive forms by shoot and root specific regulation of genes related to metal uptake, translocation and chelation.

Molecular cloning and functional analysis of a H(+)-dependent phosphate transporter gene from the ectomycorrhizal fungus Boletus edulis in southwest China.
The results suggest that BePT plays a key role in phosphate acquisition in the ectomycorrhizal fungus B. edulis and the expression of BePT was significantly upregulated at lower phosphorus availability, which may enhance phosphate uptake and transport under phosphate starvation. Expand
Diversity and characterization of Cd-tolerant dark septate endophytes (DSEs) associated with the roots of Nepal alder (Alnus nepalensis) in a metal mine tailing of southwest China
DSE was an integral component of the root system of Nepal alder growing in metal-contaminated soils, and it is more feasible to obtain heavy metal (HM) tolerant DSEs from mining areas than from no HM-polluted environments for their potential application in phytoremediation. Expand
Diverse strategies conferring extreme cadmium (Cd) tolerance in the dark septate endophyte (DSE), Exophiala pisciphila: evidence from RNA-seq data.
This study represents the first investigation of the transcriptome of DSE under Cd stress, and the results provide valuable information for future molecular studies of HMs tolerance in fungi. Expand
Identification of Glutathione S-Transferase (GST) Genes from a Dark Septate Endophytic Fungus (Exophiala pisciphila) and Their Expression Patterns under Varied Metals Stress
Although heavy metal-specific differences in performance were observed under various heavy metals in Escherichia coli BL21 (DE3) transformed with EpGSTN-31, the over-expression of this gene was able to enhance the heavy metal tolerance of the host cells and provides a primary interpretation of heavy metal detoxification for E. pisciphila.

EpNramp is a bivalent cation transporter localized in cell membrane, which is necessary for efficient translocation of both Fe and Cd, and its activities partly attributed to the tolerance of DSE to toxic and excessive Cd(2+) supplements. Expand
