Sequences, the environment and fungi

In this article we review briefly the retrieval and analysis of molecular signals from the environment in relation to fungal diversity. Such molecular diversities have been assessed for terrestrial and aquatic systems, at various study levels, using PCR-based and nucleic acid hybridization-based techniques. The approaches adopted in some of these studies will be compared, including mention of the problems encountered, and discussed in broad terms detailing the identification of sequences representing fungal groups and their activities.
