Mycorrhizal Endogone Species

Deciphering interfungal relationships in the 410-million-yr-old Rhynie chert: Sporocarp formation in glomeromycotan spores

“…Nevertheless, although no small-spored glomeromycotan fungus is described as forming sporocarps of this size and nature, it is quite conceivable that such organisms might have existed and that they might have produced groups of spores of a size similar to those of E. multiplex. The most common extant species in the Glomeraceae that produces small sporocarps enclosed by a peridium are spores (Nicolson and Gerdemann, 1968;Giovannetti et al, 1991;Schüßler and Walker, 2010). Kidston and Lang (1921b) emphasize that a special relationship appears to exist between "Fungus No.…”

“…Gerd. et Trappe; Nicolson and Gerdemann, 1968], certainly represented a suitable host for parasitic microfungi because they contain abundant and easily accessible nutrients (Bonfante et al, 1994). As the parasite develops in the lumen of the host, an increasing percentage of the host spore, including its wall, is used in the formation of the parasite sporocarp.…”

Identification and physiological significance of mycorrhizal associations of apple (Malus domestica Borkh.)

“…Many taxonomic keys of these genera and their species have been published (Nicolson and Gerdemann, 1968;Nicolson and Schenck, 1979). Recently, a dichotomous key (Hall and Fish, 1979) and synoptic keys (Schenck and Smith, 1982;Trappe, 1982) have been developed.…”

Developmental aspects of Gigaspora rosea and Glomus etunicatum, alone or in association with Alnus glutinosa

“…Because the taxonomy of vesicular-arbuscular mycorrhizal fungi (VAMF) is based primarily upon the structure and formation of their soil-borne resting spores, information on the anatomy of these spores is found regularly with species descriptions (Gerdemann and Trappe, 1974;Hall and Fish, 1979;Mosse and Bowen, 1968;Nicolson and Gerdemann, 1968;Nicolson and Schenck., 1979;Schenck and Smith, 1982;Sward et al, 1978;Trappe, 1982;Trappe and Schenck, 1982). There are relatively few studies, however, that examine the ultrastructure of VAMF resting spores.…”

“…Study of individual VAMF is currently restricted by the inability to maintain these fungi in independent culture throughout a complete life cycle. Taxonomic status and phylogeny of VAMF therefore are based primarily upon morphological and physical characteristics of fungal structures that are associated with formation of an endomycorrhizal relationship (Abbott, 1982;Abbott and Robson, 1978;Gerdemann and Trappe, 1974;Hall and Fish, 1979;Mosse and Bowen, 1968;Nicolson and Gerdemann, 1968;Nicolson and Schenck, 1979;Old et al, 1973;Schenck and Smith, 1982;Tinker, 1975;Trappe, 1982;Trappe and Schenck, 1982;Walker, 1983). Structural studies also contribute information on the development and physiology of VAM relationships between specific endophytes and specific host plants.…”
