Algal switching among lichen symbioses.
Lichens are intimate and long-term symbioses of algae and fungi. Such intimate associations are often hypothesized to have undergone long periods of symbiotic interdependence and coevolution.Expand

Positions of multiple insertions in SSU rDNA of lichen-forming fungi.
Lichen-forming fungi, in symbiotic associations with algae, frequently have nuclear small subunit ribosomal DNA (SSU rDNA) longer than the 1,800 nucleotides typical for eukaryotes. The lichen-formingExpand

Geographic variation in algal partners of Cladonia subtenuis (Cladoniaceae) highlights the dynamic nature of a lichen symbiosis.
Multiple interacting factors may explain variation present in symbiotic associations, including fungal specificity, algal availability, mode of transmission and fungal selectivity. To separate theseExpand

Multiple origins of lichen symbioses in fungi suggested by SSU rDNA phylogeny.
Phylogenetic hypotheses provide a context for examining the evolution of heterotrophic lifestyles. The lichen lifestyle, which is the symbiotic association of fungi with algae, is found in variousExpand

Strong fungal specificity and selectivity for algal symbionts in Florida scrub Cladonia lichens
Symbiosis is a major theme in the history of life and can be an important force driving evolution. However, across symbioses, it is difficult to tease apart the mechanisms that structure theExpand

A nomenclature for fungal PCR primers with examples from intron-containing SSU rDNA
AbstractWe present a compilation of polymerase chain reaction primers (oligonucleotides) used to amplify and sequence the small subunit of nuclear ribosomal DNA. To simplify use of these primers we...

Small subunit rDNA variation in a population of lichen fungi due to optional group-I introns.
A natural population of the lichen-forming ascomycetous fungus, Cladonia chlorophaea, contained individuals with small subunit ribosomal DNA (SSU rDNA) of at least four different size classes andExpand

SSU rDNA phylogeny of cladoniiform lichens.
To examine phylogenetic relationships among the "cladoniiform" lichenized fungi, i.e., the families Cladoniaceae, Baeomycetaceae, Icmadophilaceae, Stereocaulaceae, and Siphulaceae, and to provideExpand
