Ectomycorrhizas involving sebacinoid mycobionts

Mycological Research, 2003
Nuclear ribosomal DNA sequences characteristic of Sebacinaceae were detected by direct amplification of DNA from field collected ectomycorrhizal samples. A study was undertaken to confirm the formation of ectomycorrhizas by Sebacinaceae and to characterise representative samples genetically, morphologically and ultrastructurally.

Ectomycorrhizae in reforestation

Canadian Journal of Forest Research, 1990
In view of the possible applications of ectomycorrhizae to forestry, this paper discusses the important functions of ectomycorrhizae, the conditions affecting their formation, and methods for the production and application of inoculum. A rationale for selecting appropriate ectomycorrhizal fungi and considerations in selecting sites where ...

Ectomycorrhiza Development: A Molecular Perspective

1995
The symbiosis between trees and soilborne ectomycorrhizal fungi results in an intimate relationship between the plant and its symbiotic partner. It provides several benefits to both the host plant and the fungal associate. The prospecting and absorbing activities of the extraradical hyphae are committed to responding to the metabolic needs of the plant.

Ectomycorrhiza of Populus

Forest Ecology and Management, 2015
Abstract Populus species and hybrids (poplars, aspens, cottonwoods, etc.) are important trees in forestry and landscaping, whereas Populus trichocarpa is an internationally accepted model organism for tree research. Populus roots often form symbiotic relationships with ectomycorrhizal partners, and such relationships improve the host tree’s general ...

Identification of Ectomycorrhizas

2002
The present review give an exhaustive account of various criteria employed in identification of ectomycorrhizal fungi with specific reference to particular fungi. The ectomycorrhizas are classified on the basis of thier anatomical and morphological features.

Metal toxicity and ectomycorrhizas

Physiologia Plantarum, 2000
Metal 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, 1987
Summary 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, 2012
Climate 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, 1990
Abstract 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.
