“…This research is essential, as some EMF can be very effective in the nursery, but the effects may disappear after a few years in the field (Natarajan, Mohan, and Ingleby 1992;Munyanziza, Kehri, and Bagyaraj 1997). Although the beneficial effects of ectomycorrhizal inoculation may be less obvious in the field, the multiple biotic and abiotic factors that stress plants justify the presence of these fungi in the roots (Garcia et al 2010).…”

The objective of this study was to determine individual and combined inoculation effects with ectomycorrhizal fungi (EMF) (Amanita muscaria, AM; Suillus luteus, SL; and Amanita sp., AS) on seedling growth and P uptake of Pinus patula, P. oocarpa, and P. tecunumanii. Beneficial effects of ectomycorrhizal inoculation depended on the plant species × inoculum combinations. In the case of P. patula, the benefit was evident only in P uptake and this occurred only when the three fungi were concomitantly applied. In P. tecunumanii, the effects were associated not only with P uptake but also with plant growth and not only with the triple inoculation but also with the individual (AS) and dual (AM + AS) inoculations. In P. oocarpa, AS inoculation enhanced both plant growth and P uptake, while AM inoculation only improved plant growth; triple and dual inoculation (SL+AM and SL+AS) also increased plant growth but not P uptake.

Do nutrient additions alter carbon sink strength of ectomycorrhizal fungi?

et al. 2001

Summary• Carbon sink strength differences are examined here between ectomycorrhizal fungi in interaction with additions of ammonium and apatite (a phosphorus-and calcium-containing mineral).• Pinus muricata associated with Paxillus involutus and four suilloid isolates ( Suillus pungens and members of three Rhizopogon section Amylopogon species groups) were used in microcosm nutrient addition experiments.• The associations differed in ectomycorrhizal biomass, mycelial growth rate, biomass and respiration. P. involutus produced the lowest biomass of ectomycorrhizal connections to P. muricata , but it consumed proportionally more carbon per connection and transferred more than twice as much ammonium to the host per unit mycorrhizal biomass. Paxillus also colonized the soil more rapidly and intensely than the other fungi, but its mycelial respiration was lowest. Ammonium and apatite addition resulted in a marked increase in respiration and mycelial biomass, respectively, by the suilloid fungi.• The high carbon cost of ammonium uptake is suggested as one explanation for reduced sporocarp production and mycelial growth by ectomycorrhizal fungi commonly found after high levels of nitrogen addition.

“…This may be a common pattern for Suillus species : studies in other ecosystems have also found a low percentage of Suillus spp. mycorrhizas along with a high production of basidiomes (Danielson, 1984 ;Natarajan, Mohan & Ingleby, 1992). * To whom correspondence should be addressed at (present address) : Dept.…”

Genetic structure of a natural population of the ectomycorrhizal fungus Suillus pungens

1998

Sequence-based markers were developed to study the genetic structure and reproductive biology of the ectomycorrhizal fungus Suillus pungens Thiers & Smith in a Bishop pine (Pinus muricata D. Don) forest. Six different basidiome genotypes were found in a 1200 m# area. Five of the six genotypes were represented by single basidiomes. The remaining genotype comprised 13 basidiomes and covered an area of at least 300 m#, with maximum measured dimensions of 40 m and 14 m. This is the largest genet of an ectomycorrhizal fungus described to date, and is likely the result of vegetative growth, because analysis of single spore isolates eliminates the possibility of genetic identity resulting from either apomixis or fortuitously indistinguishable recombinant genotypes. Genetic analysis also shows that although out-crossing appears to predominate in the population, at least a low percentage (1n4 %) of spores are secondarily homothallic.The combination of extensive vegetative growth and abundant fruiting suggests S. pungens utilizes more carbon than might be expected for a species which accounts for 3 % of the total ectomycorrhizal abundance at the site. Additional carbon might come from either more efficient host-fungus transfer, pooling of carbon from the roots of different host plants, or saprophytism.
