- Abstract
- Many ericaceous species colonize as pioneer plants substrates ranging from
arid sandy soils to moist mor humus, in association with their mycorrhizal
fungi. Thanks to the symbiosis with ericoid mycorrhizal fungi, ericaceous
plants are also able to grow in highly polluted environments, where metal
ions can reach toxic levels in the soil substrate. For a long time this
mycorrhizal type has been regarded as an example of a highly specific
interaction between plants and fungi. More recent studies have been
challenging this view because some ericoid mycorrhizal endophytes seem also
able to colonise plants from very distant taxa. A molecular approach has
allowed the investigation of genetic diversity and molecular ecology of
ericoid mycorrhizal fungi, and has revealed that ericaceous plants can be
very promiscuous, with multiple occupancy of their thin roots. The
molecular analysis of sterile morphotypes involved in this symbiosis has
also led to deeper understanding of the species diversity of ericoid fungi.
Genetic polymorphism of ericoid fungi is wider than previously thought, and
often increased by the presence of Group I introns in the nuclear small
subunit rDNA. (literal)
