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.

Differential ability of ectomycorrhizas to survive drying
Mycorrhiza, 2007To test the hypothesis that, depending on the fungal symbiont, ectomycorrhizas are differentially affected by severe drought stress, we developed a simple method to quantify the loss of vitality of excised ectomycorrhizal tips subjected to drying under controlled conditions.

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

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).

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

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.

4 Histochemistry of Ectomycorrhiza
1991Publisher Summary This chapter presents the history of ectomycorrhiza. To study some aspects of the development and structure of ectomycorrhiza skilled microscopists and often sophisticated equipment are required. There are available, however, a range of techniques to study structural and histochemical features of ectomycorrhiza.

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.

2 Characterization of Ectomycorrhiza
1991Publisher Summary This chapter discusses the characterization of ectomycorrhiza. Ectomycorrhiza structures consist of fungal tissues, the arrangement and organization of which can be used to describe fungal species in the same way as any other taxonomically suitable feature. Their characteristics are well conserved.

Nitrogen Assimilation: Enzymology in Ectomycorrhizas
1995Ectomycorrhizas are symbiotic associations between woody plant roots, mainly trees, and fungi that form spontaneously under natural conditions and contribute to host growth.The beneficial effects of ectomycorrhizas are mainly due to the enhanced nutrient acquisition by the host as a result of nutrient uptake by the fungal symbionts (Melin and Nilsson ...
