Recombination and genetic differentiation among natural populations of the ectomycorrhizal mushroom Tricholoma matsutake from southwestern China
The analyses of gene and genotype frequencies within populations indicated that most loci did not deviate from Hardy–Weinberg equilibrium in most populations and that alleles among loci were in linkage equilibrium in the majority of the local populations, consistent with the hypothesis that sexual reproduction and recombination play an important role in natural populations of this species.

Arbuscular mycorrhizal status of plants and the spore density of arbuscular mycorrhizal fungi in the tropical rain forest of Xishuangbanna, southwest China
Fungi belonging to the genera Acaulospora and Glomus are the dominant AMF in the soil of the tropical rain forest of Xishuangbanna. Expand
Differences of arbuscular mycorrhizal fungal diversity and community between a cultivated land, an old field, and a never-cultivated field in a hot and arid ecosystem of southwest China
Of resembled NCF more than CL in AMF spore density, species richness, and community composition, which means that AMF community in the OF has been developing from cultivated land to natural habitat. Expand
Unraveling the role of dark septate endophyte (DSE) colonizing maize (Zea mays) under cadmium stress: physiological, cytological and genic aspects
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 diversity of arbuscular mycorrhizal fungi and their distribution patterns related to host-plants and habitats in a hot and arid ecosystem, southwest China.
The diversity of AMF colonizing the same plant species was higher in the UL than in the FL, which confirmed strongly from the molecular evidence that soil disturbance reduced AMF population and species richness, and supported the previous hypothesis that AMF communities were more influenced by habitats compared with host preference.

Bacterial Diversity in Mine Tailings Compared by Cultivation and Cultivation-independent Methods and their Resistance to Lead and Cadmium
To examine bacterial community composition in rhizosphere of plants colonizing on mine tailings and phylogenetic differences between subcommunities resistant to different metals, we constructed fourExpand
Bacterial diversity at different depths in lead-zinc mine tailings as revealed by 16S rRNA gene libraries.
Bacterial communities at 10 cm, 100 cm, and 200 cm depths in a 100-year-old lead-zinc tailing heap were evaluated by constructing 16S rRNA gene libraries, finding that species composition was significantly different between the three libraries. Expand
Species clarification of oyster mushrooms in China and their DNA barcoding
Molecular identification of the species complex based on sequences of the internal transcribed spacer region (ITS), translation elongation factor 1-α (TEF1), and two genes that encode subunits of RNA polymerase II (RPB1 and RPB2) indicated thatRPB2 was the most promising candidate segment of DNA barcode for the P. ostreatus species complex.

Multivariate statistical analysis for the surface water quality of the Luan River, China
In order to analyze the characteristics of surface water resource quality for the reconstruction of old water treatment plant, multivariate statistical techniques such as cluster analysis and factorExpand
Removal of organic matter in freshwater sediment by microbial fuel cells at various external resistances
BACKGROUND: Besides acting as power sources, sediment microbial fuel cells (SMFC) could be explored to remove organic matter in sediments and then maintain the water quality in aquatic environments.Expand
