An in vitro method for establishing mycorrhizae on coniferous tree seedlings
A method for in vitro synthesis of mycorrhizae on coniferous tree seedlings and fungi established within 2–3 weeks after inoculation and within 2 months after germination of seedlings.
The effect of drought on mycorrhizas of beech (Fagus sylvatica L.): changes in community structure, and the content of carbohydrates and nitrogen storage bodies of the fungi
The data show that, within certain limits, an increase in drought causes a shift in plant/fungus communities, and the shift in the pattern of fungus-specific compounds could possibly be used as a sensitive measure of physiological stress imposed on this symbiosis.
Recent advances in exploring physiology and biodiversity of ectomycorrhizas highlight the functioning of these symbioses in ecosystems.

The limits of the laboratory and the field approaches are discussed, and recent advances in identification of fungal partners in ectomycorrhizas by analysing the internal transcribed spacer of ribosomal DNA are presented, which can help to resolve sampling problems in field studies.

Characterization of these compounds provides the foundation for molecular analysis of the fungus-bacterium interaction in the ectomycorrhizal symbiosis between fly agaric and spruce.
Mycorrhiza helper bacterium Streptomyces AcH 505 induces differential gene expression in the ectomycorrhizal fungus Amanita muscaria.
It is suggested that AcH 505 and AcH 1003 enhance mycorrhiza formation mainly as a result of promotion of fungal growth, leading to changes in fungal gene expression.
Carbohydrate metabolism in ectomycorrhizas: gene expression, monosaccharide transport and metabolic control
This review covers concepts at the molecular level concerned with the fungal carbohydrate supply in symbiosis, and discusses strategies used by host plants to compensate (and perhaps restrict) carbohydrate drain to thefungal partner.
Isolation and characterization of a general amino acid permease from the ectomycorrhizal fungus Amanita muscaria
Gene expression and amino acid uptake data together indicate two main functions for AmAAP1: uptake of amino acids from soil for fungal nutrition, and prevention of an amino acid loss by hyphal leakage in the absence of a suitable N source.
Adenylate Levels, Energy Charge, and Phosphorylation Potential during Dark-Light and Light-Dark Transition in Chloroplasts, Mitochondria, and Cytosol of Mesophyll Protoplasts from Avena sativa L.
The compartmentation of cellular energy relations during dark-light and light-dark transitions was studied by means of a newly developed technique to fractionate oat and Adenylate kinase was found to be exclusively associated with chloroplasts and mitochondria.
Aquaporins in poplar: What a difference a symbiont makes!
Measurements of the hydraulic conductance of intact root systems revealed an increased water transport capacity of mycorrhized poplar roots, and indicate that changes in the properties of the plasma membrane as well as those of the apoplast are responsible for the increased root hydraulic Conductance in ectomycorrhizal symbiosis.
Production of fungal and bacterial growth modulating secondary metabolites is widespread among mycorrhiza-associated streptomycetes
Mycorrhiza associated streptomycetes appear to have an important role in inhibiting the growth of fungi and bacteria, and potentially novel metabolites were produced by strains that were less antagonistic to fungi.
