Colour Atlas of Ectomycorrhizae

  title={Colour Atlas of Ectomycorrhizae},
  author={Reinhard Agerer},
Ectomycorrhizae, the symbiotic organs of fungi and roots of needle and broad-leaved trees, create distinct anatomical features. These characters are preferentially dependent, influenced and fashioned by the fungal hyphae during the ontogeny of these essentially important structures of root systems. Without ectomycorrhizae, the trees, which are completely dependent on them, are unable to grow. Many features of the ectomycorrhizae are functionally crucial, i.e. they influence the growth of trees… 
Fungal relationships and structural identity of their ectomycorrhizae
A limited number of species could be considered, some general conclusions are possible and the most important ectomycorrhizal relationships within Hymenomycetes and within Ascomycota contribute to the symbiosis.
The surface of ectomycorrhizal roots and the interaction with ectomycorrhizal fungi.
A hydrophobic root surface was postulated and a cuticle-like layer on the surface of short roots may be the substrate for adhesion of ectomycorrhizal fungi (Kottke 1997), and recent ultrastructural studies comparing long and short roots have supported this hypothesis by revealing the origin of the cuticles- like layer on short, but not on long roots.
The ectomycorrhizal symbiosis: Life in the real world
It is shown that it would take between 3 and 14 million mycorrhizal tips, or 1800 km of hyphae, to supply the N in one sporocarp of Boletus edulis, and the mantle formed by the fungus over the root tip is the likely site of storage for the N and P required for sporocaru production.
Molecular Characterization of the Mycorrhizas of Woody Plants
The term mycorrhiza, literally translated as “fungus root”, denotes the presence of a functional and structural union between a fungus and the root system of a plant. These symbioses are an integral
Scleroderma areolatum ectomycorrhiza on Fagus sylvatica L.
A morphological and anatomical description of tree nursery derived ectomycorrhizae of Scleroderma areolatum on Fagus sylvatica, grown for several years in a climatized room is provided and the phylogenetic analysis positioned the newly described ectomyCorrhiza together with Sclerodingma verrucosum and Sclerodma cepa in a single clade with a taxon name SH005470.07FU.
Resupinate Ectomycorrhizal Fungal Genera
There are an increasing number of studies which compare ECM community structure both on the roots below and as sporocarps above ground and it is thought that some ECM fungi may not form sporoccarps, while others may form inconspicuous sporOCarps which are easily overlooked.
The AD-type ectomycorrhizas, one of the most common morphotypes present in truffle fields, result from fungi belonging to the Trichophaea woolhopeia species complex
It is shown that AD-type ECMs result from host plant colonization by the pyronemataceous species Trichophaea woolhopeia, and the 28S and internal transcribed spacer (ITS) rDNA regions are analyzed to sustain the hypothesis that T. woolh hopeia is a species complex.
Ectomycorrhizae associated with Castanopsis fargesii (Fagaceae) in a subtropical forest, China
This is the first study to characterize the below-ground ECM communities and anatomical structures in a subtropical evergreen broad-leaved forest of southwest China and identify 17 ECM fungi based on the analysis of ITS sequences.
Are Trechisporales ectomycorrhizal or non-mycorrhizal root endophytes?
Analysis of isotope abundance in the same Brazilian site and in French Guiana showed that Trechispora thelephora has high 15N abundance and is often intermediate between ectomycorrhizal and saprotrophic species in 13C abundance, which is congruent with a plant biotrophic ecology, perhaps ectomy CorrhizAL.
Plants and Their Ectomycorrhizosphere: Cost and Benefit of Symbiotic Soil Organisms
This work quantifies the exploration type specific space occupation under the influence of twice-ambient ozone concentrations and estimates the carbon cost the tree has to pay for and addresses enzymatic capacities of ectomycorrhizal communities and focus on bacteria being associated with the mycelium.
