PIXE analysis to estimate the elemental composition of ectomycorrhizal rhizomorphs grown in contact with different minerals in forest soil
(2002) In FEMS Microbiology Ecology 39(2). p.147-156- Abstract
- The aim of this study was to investigate possible interactions between minerals and ectomycorrhizal (EM) mycelia. Fungal rhizomorphs growing in association with apatite and/or biotite were sampled both from a laboratory experimental system (Rhizopogon sp. and Pinus muricata) and from mesh bags buried in forest soil in the field. The elemental composition of the samples was analyzed with particle-induced X-ray emission (PIXE). Many EM rhizomorphs associated with apatite in laboratory systems and in mesh bags contained larger amounts of Ca (mean ranges between 12 and 31 mg Ca g(-1)) than similar rhizomorphs connected to acid-washed sand (range 0.3-3.5 mg Ca g(-1)). Ca originating from apatite was deposited as calcium oxalate crystals on the... (More)

Ca originating from apatite was deposited as calcium oxalate crystals on the surface of the rhizomorphs. EM mycelium produced in mesh bags had a capacity to mobilize 0.6 mg P kg(-1) year(-1) from apatite-amended sand (which is 0.04% of the added apatite). A high concentration of K in some rhizomorphs (up to 11 mg K g(-1)) suggests that these fungi are good accumulators of K and may have a significant role in transporting K to trees.
