Its rDNA sequence comparison of ericoid mycorrhizal endophytes from Woollsia pungens

Genetic diversity of root‐associated fungal endophytes from Calluna vulgaris at contrasting field sites

“…Further evidence is provided by the fact that endophytes isolated from Epacridaceae can form morphologically typical mycorrhizal associations with Ericaceae hosts (Reed, 1989(Reed, , 1996Liu et al, 1998). Only an Oidiodendron species (probably O. maius Barron) has been identified as an endophyte of an Epacridaceae host in the field and molecular data suggest that, in common with those from Ericaceae, most endophytes probably have affinities with Leotiales (McLean et al, 1999 ;Chambers et al, 2000). While the taxonomic status of ericoid mycorrhizal endophytes of Ericales hosts has received some attention, far less effort has been focused on determining the diversity of endophyte assemblages present within root systems of a host taxon at a single field site or of the same taxon at different field sites.…”

“…While the taxonomic status of ericoid mycorrhizal endophytes of Ericales hosts has received some attention, far less effort has been focused on determining the diversity of endophyte assemblages present within root systems of a host taxon at a single field site or of the same taxon at different field sites. Results of several studies indicate that a single stand of an Ericales host species might be colonized by several endophyte taxa, as can the root system of an individual plant within such a stand (Perotto et al, 1990(Perotto et al, , 1995Xiao & Berch, 1996 ;Hambleton & Currah, 1997 ;Liu et al, 1998 ;Chambers et al, 2000). Although detailed functional studies have yet to be performed on endophytes other than H. ericae, it seems likely that such diversity might be of considerable functional significance to the hosts (Smith & Read, 1997).…”

“…Although the separation of the two clades received strong (100%) bootstrap support in the neighbourjoining analysis, the node at the base of Clade II, along with several other nodes within this clade, was poorly supported. Support for the affinities of these isolates with Leotiales was thus strong (Monreal et al, 1999 ;Chambers et al, 2000) ; however, further sequence data and more detailed analysis might be required in order to resolve relationships within this clade.…”

OmZnT1 and OmFET, two metal transporters from the metal-tolerant strain Zn of the ericoid mycorrhizal fungus Oidiodendron maius, confer zinc tolerance in yeast

“…O. maius ( Barron, 1962) is an ascomycete (class Leotiomycetes) that can establish endomycorrhizal symbioses with the roots of ericaceous plants ( Perotto et al, 1996, Hambleton et al, 1998and Chambers et al, 2000. Among fungi, mycorrhizal species represent an important community in metal polluted soils, as they form mutualistic symbioses which can alleviate the effects of heavy metal toxicity to their host plant ( Adriaensen et al, 2005 andAdriaensen et al, 2006) and provide a more balanced access to mineral elements, either by improving supply of essential elements or by reducing uptake of toxic elements ( Bellion et al, 2006 andColpaert et al, 2011).…”

Identification and community profiling of Vaccinium membranaceum root-associated fungi over an elevation gradient in BC's eastern rocky mountains.

“…with teleomorphs in the order Onygenales (Perotto et al 2002) have also been identified as ericoid mycorrhizas. These taxa are the most commonly identified ERM fungi (Allen et al 2003;Chambers et al 2000;Hambleton and Currah 1997;Monreal etal. 1999;Perotto etal.…”
