Metal toxicity and ectomycorrhizas
Physiologia Plantarum, 2000Metal toxicity (Al and heavy metals) is a major constraint affecting root growth in a number of natural or managed ecosystems. Fine roots of the majority of plant species are associated with mycorrhizal fungi, which may modify the sensitivity of roots to metal stress.

ECTOMYCORRHIZA FORMATION IN EUCALYPTUS
New Phytologist, 1987Summary Cortinarius and Hysterangium species are a dominant component of the macrofungi in eucalypt forests of Western Australia, and their hyphae occupy 10 % of the soil surface area. Anatomical studies of jarrah (Eucalyptus marginata Donn ex Sm.) and karri (E. diversicolor F.

Ectomycorrhizas and climate change
Fungal Ecology, 2012Climate changes have important consequences for plant communities and their root symbionts. The distribution of tree species within temperate, boreal and tropical biomes will be altered, as palaeoecological studies have demonstrated for previous climate change events. Predicted effects on ectomycorrhizal (ECM) associations include migration of host and

Ectomycorrhizas and forest decline
Agriculture, Ecosystems & Environment, 1990Abstract Forest decline has been occuring in central Europe over the last decade. Beside natural stress factors the effects of various air pollutants and their derivates have been stressed as causes of this phenomenon. The “new type” of forest dying is associated with soil degradation, nutrient deficiencies, ŕoot decline and mycorrhizal dysfunction.

Carbon allocation in ectomycorrhizas
Physiological and Molecular Plant Pathology, 2000Abstract In ectomycorrhizas, mutual benefit between the plant and fungal partners is due to the exchange of plant-derived carbohydrates for amino acids and nutrients supplied by the fungus. Sucrose, the major plant transport carbohydrate, is hydrolysed in the common apoplastic interface, and monosaccharides are taken up by both the fungal partner and

2000
The term mycorrhiza, coined by Frank literally means ‘fungus-root’. It refers to a symbiotic association between fungi and the feeder roots of higher plants. It is now well documented that with the exception of aquatics, some halophytes and few other plants, all form mycorrhizae in natural roots to varying degrees (Mukerji and Mandeep, 1998).

Ectomycorrhizae Associated With Jarrah
Australian Journal of Botany, 1981Three major morphological types of ectomycorrhizae have been distinguished on roots of Eucalyptus marginara (jarrah). These were broadly classified as white, brown and black types. The variation in type of ectornycorrhizae and number of infected tips with season and depth in the soil were monitored at three forest sites.

Fossil ectomycorrhizae from the Middle Eocene
American Journal of Botany, 1997Fossil ectomycorrhizae were found recently among permineralized plant remains in the middle Eocene Princeton chert of British Columbia. The ectomycorrhizae are associated with roots of Pinus and have a Hartig net that extends to the endodermis, a pseudoparenchymatous mantle, and contiguous extramatrical hyphae that are simple‐septate.

Ectomycorrhiza and Secondary Metabolites
2010Ectomycorrhizal symbiosis leads to the diversification of both the mycobiont and their host. Differences in organogenetic programs are reflected in ectomycorrhizal root morphology, but key developmental programs are triggered in the physiological processes in both symbiosis partners and are dependent on hormones and secondary signals.

Somatic Incompatibility in Ectomycorrhizas
1995Describing and identifying fungal individuals, i.e. genetically unique mycelia, are key problems in studies of the evolutionary and population biology of ectomycorrhizal fungi. It is only recently that the concept of fungal individualism and methods to identify fungal individuals have been developed (Todd and Rayner 1980).
