Lone Frette et al.
To test if the quality and concentration of dissolved nitrogen (N) species could be a selective force in shaping bacterioplankton community structure, competition for various N compounds among five heterotrophic marine bacteria (Pseudomonas...
Culture-independent assessment of Rhizobiales-related alphaproteobacteria and the diversity of Methylobacterium in the rhizosphere and rhizoplane of transgenic eucalyptus [0.03%]
非培养法评估与根际和根表层转基因桉树有关的土壤中根瘤菌群植生菌的多样性

Fernando Dini Andreote et al.
The rhizosphere is an ecosystem exploited by a variety of organisms involved in plant health and environmental sustainability. Abiotic factors influence microorganism-plant interactions, but the microbial community is also affected by expre...
Epizoic communities of prokaryotes on healthy and diseased scleractinian corals in Lingayen Gulf, Philippines [0.03%]

Mark Arboleda
In search for microbiological indicators of coral health and coral diseases, community profiles of coral-associated epizoic prokaryotes were investigated because of their dual potential as a source of coral pathogens and their antagonists. ...
Vertical distribution of a soil microbial community as affected by plant ecophysiological adaptation in a desert system [0.03%]
植物生态生理适应对沙漠土壤微生物区系垂直分布的影响
G Barness,S Rodriguez Zaragoza,I Shmueli et al.
G Barness et al.
The spatial and temporal patterns of resource distribution in a desert system have been shown to influence a number of soil biota components and processes. The pattern of possible different resources supplied by two typical halophyte shrubs...
Role of plants in the vegetative and reproductive growth of saprobic basidiomycetous ground fungi [0.03%]
植物在腐生伞菌类子实体生长和营养体生长中的作用研究进展

Gerhard Gramss
Non-symbiotic microorganisms engineered or expensively selected to degrade xenobiotic hydrocarbons or modify heavy-metal uptake of plants in soil remediations die back after their introduction into the target soils. Mycelia of saprobic basi...
Moths that vector a plant pathogen also transport endophytic fungi and mycoparasitic antagonists [0.03%]
携带有植物病原体的蛾类也携带内生真菌和拟寄生拮抗剂
