Uncommon ectomycorrhizal networks: richness and distribution of Alnus-associating ectomycorrhizal fungal communities.
The level of specificity is a key evolutionary and ecological parameter of any symbiotic interaction. Where diverse classes of mutualists interact, extracting the drivers of spatial–temporal variation in community composition is also fundamental to understanding the interaction. Ectomycorrhizal (EM) plants and fungi typically associate with many symbionts both as individuals and across a specie...
متن کاملInterspecific Mycorrhizal Networks and Non-networking Hosts: Exploring the Ecology of the Host Genus Alnus
While the dominant ectomycorrhizal (ECM) fungi in most temperate and tropical forests have low host specificity, a commonly cited exception to this pattern is the ECM fungal community associated with the host genus Alnus. In this chapter, we discuss multiple hypotheses that have been put forth to explain the specificity of the Alnus ECM symbiosis and consider their strengths and weaknesses in l...
متن کاملSOURCES OF VARIATION IN THE SYMBIOTIC ASSOCIATION BETWEEN ALNUS AND FRANKIA IN INTERIOR ALASKA by
Symbioses between plants and nitrogen (N) fixing bacteria are ecologically and economically important interactions with complex evolution and ecology. Theoretical and experimental studies suggest that host specificity and environmental variation are important determinants of both evolutionary and ecological patterns in such interactions, but detailed descriptions of these parameters in natural ...
متن کاملPhylogeny and assemblage composition of Frankia in Alnus tenuifolia nodules across a primary successional sere in interior Alaska.
In nitrogen (N) fixing symbioses, host-symbiont specificity, genetic variation in bacterial symbionts and environmental variation represent fundamental constraints on the ecology, evolution and practical uses of these interactions, but detailed information is lacking for many naturally occurring N-fixers. This study examined phylogenetic host specificity of Frankia in field-collected nodules of...
متن کاملPhylogeny of the ectomycorrhizal mushroom genus Alnicola (Basidiomycota, Cortinariaceae) based on rDNA sequences with special emphasis on host specificity and morphological characters.
Alnicola (=Naucoria, pro parte) is a mushroom genus of strictly temperate, obligately ectomycorrhizal species, traditionally included in the family Cortinariaceae. Most Alnicola spp. are primarily host specific on Alnus, although a few are mycobionts of Salix or other hosts. The different species of Alnicola exhibit unique morphological (cystidia, pileipellis) and cytological (dikaryotic or mon...
