Ectomycorrhizal diversity of oak forests in the Sierra Madre Oriental, Mexico.

A survey was conducted to investigate the diversity of ectomycorrhizal fungi associated with Quercus in the Sierra Madre Oriental region. Approximately 700 root tips were collected from the organic horizon at sites in Nuevo León and Tamaulipas in northeastern Mexico. Sequences of the internal transcribed spacer region of nuclear ribosomal DNA were obtained for the purpose of identification. While the diversity of host trees was relatively low, mycorrhizal diversity was high. Many of these sequences could not be identified down to the species level, which contrasts with results from similar mycorrhizal surveys done in temperate forests. Even within genera for which fruit bodies were concurrently collected, such as Tuber, mycorrhizal sampling yielded unique phylotypes.
