Estimating the Phanerozoic history of the Ascomycota lineages: combining fossil and molecular data.
- C. Beimforde, K. Feldberg, +8 authors A. Schmidt
- Biology, Medicine
- Molecular phylogenetics and evolution
- 1 September 2014
The phylum Ascomycota is by far the largest group in the fungal kingdom. Ecologically important mutualistic associations such as mycorrhizae and lichens have evolved in this group, which are regarded… Expand
Lichen Guilds Share Related Cyanobacterial Symbionts

- 19 July 2002
Lichen symbioses represent a major way of life among the Fungi. Almost one-fifth of all known fungal species are lichenized, and about 1500 species of lichens contain cyanobacterial photobionts, most… Expand

Lichens are symbiotic associations between fungi and photosynthetic algae or cyanobacteria. Microcystins are potent toxins that are responsible for the poisoning of both humans and animals. These… Expand
Discovery of Rare and Highly Toxic Microcystins from Lichen-Associated Cyanobacterium Nostoc sp. Strain IO-102-I

ABSTRACT The production of hepatotoxic cyclic heptapeptides, microcystins, is almost exclusively reported from planktonic cyanobacteria. Here we show that a terrestrial cyanobacterium Nostoc sp.… Expand
Cyanobiont specificity in some Nostoc‐containing lichens and in a Peltigera aphthosa photosymbiodeme
- P. Paulsrud, J. Rikkinen, P. Lindblad
- Biology
- 1 July 1998
The cyanobacterial symbionts in some Nostoc-containing lichens were investigated using the nucleotide sequence of the highly variable cyanobacterial tRNALeu (UAA) intron. When comparing different… Expand
