Characterization of Pinus ectomycorrhizas from mixed conifer and pygmy forests using morphotyping and molecular methods
, Canadian Journal of Botany, Vol: 79, Pages: 1211-1216, ISSN: 0008-4026We used morphotyping and molecular methods to characterize ectomycorrhizas of bishop pine (Pinus muricata D. Don) and Bolander pine (Pinus contorta ssp. bolanderi (Parl.) Critchf.) from mixed conifer and hydric pygmy forests on the northern California coast. Sixteen ectomycorrhizal morphotypes were described, producing 15 internal transcribed spacer restriction fragment length polymorphism (ITS-RFLP) types, and 12 were identified via ITS sequencing. From a given site, all root tips of a specific morphotype produced identical ITS-RFLP patterns. However, sometimes two morphotypes produced the same ITS-RFLP type, and sometimes samples of the same morphotype from two different sites produced two different ITS-RFLP types. These results indicate that surveys of ectomycorrhizal fungi based on morphology alone are not sufficient, and that grouping morphotypes prior to molecular analysis can expedite the process. Ectomycorrhizas from mixed conifer included Russuloid sp., Tomentella sublilacina (Ellis & Holw.) Wakef., Tuber sp., and two Thelephoroid species. Ectomycorrhizas from hydric pygmy included two Dermocybe spp., a Cortinarius sp., two Thelephoroid spp., and Suillus tomentosus (Kauffman) Singer. Both plant communities contained Cenococcum geophilum Fr.:Fr. The hydric pygmy sites were more similar to each other than to the mixed conifer site (Jaccard similarity). The presence of ectomycorrhizal taxa in one plant community type may reflect biotic (host specificity) or abiotic (soil fertility or hydrology) adaptation.

Extreme specificity in epiparasitic Monotropoideae (Ericaceae): widespread phylogenetic and geographical structure.
, Molecular Ecology, Vol: 10, Pages: 2285-2295, ISSN: 0962-1083The Monotropoideae (Ericaceae) are nonphotosynthetic plants that obtain fixed carbon from their fungal mycorrhizal associates. To infer the evolutionary history of this symbiosis we identified both the plant and fungal lineages involved using a molecular phylogenetic approach to screen 331 plants, representing 10 of the 12 described species. For five species no prior molecular data were available; for three species we confirmed prior studies which used limited samples; for five species all previous reports are in conflict with our results, which are supported by sequence analysis of multiple samples and are consistent with the phylogenetic patterns of host plants. The phylogenetic patterns observed indicate that: (i) each of the 13 plant phylogenetic lineages identified is specialized to a different genus or species group within five families of ectomycorrhizal Basidiomycetes; (ii) mycorrhizal specificity is correlated with phylogeny; (iii) in sympatry, there is no overlap in mature plant fungal symbionts even if the fungi and the plants are closely related; and (iv) there are geographical patterns to specificity.
