Lichen-Like Symbiosis 600 Million Years Ago
@article{Yuan2005LichenLikeS6, title={Lichen-Like Symbiosis 600 Million Years Ago}, author={Xunlai Yuan and Shuhai Xiao and Thomas N. Taylor}, journal={Science}, year={2005}, volume={308}, pages={1017 - 1020} }
The fossil record of fungi and lichens is scarce. Here we report the discovery of lichen-like fossils, involving filamentous hyphae closely associated with coccoidal cyanobacteria or algae, preserved in marine phosphorite of the Doushantuo Formation (between 551 and 635 million years old) at Weng'an, South China. These fossils indicate that fungi developed symbiotic partnerships with photoautotrophs before the evolution of vascular plants.

15 The Symbiotic Phenotype of Lichen-Forming Ascomycetes and Their Endo- and Epibionts
- Environmental Science

The focus is on the symbiotic phenotype of lichen-forming ascomycetes, i.e. the main types of thallus morphologies, the functional anatomy of macrolichens and their growth patterns, the fine structure and composition of cell wall types of Lichen photobionts and their impact on the mycobiont–photobionT interface.

The fossil demonstrates that distinguishing features of Phyllopsora have remained unchanged for tens of millions of years and provides the first detailed views of mycobionT-photobiont contacts in Tertiary green algal lichens.

Protein sequence analyses indicate that green algae and major lineages of fungi were present 1000 Ma and that land plants appeared by 700 Ma, possibly affecting Earth's atmosphere, climate, and evolution of animals in the Precambrian.

A phylogenetic interpretation implies that (1) the phylogenetic divergence between the Florideophyceae and its sister group, the Bangiales, must have taken place before Doushantuo time-an inference supported by the occurrence of bangialean fossils in Mesoproterozoic rocks.

The results suggest that all three cases represent independent fungal phylogenetic species, which can undergo their whole sexual lifecycle either as lichens or as saprotrophs, and are suggested to be common in the Stictidaceae.

Geosiphon pyriforme, a fungus forming endocytobiosis withNostoc (Cyanobacteria), is an ancestral member of the glomales: Evidence by SSU rRNA Analysis
- BiologyJournal of Molecular Evolution

Geosiphon shows the ability of a Glomus-like fungus to form a “primitive” symbiosis with a unicellular photcautotrophic organism, in this case a cyanobacterium, leading to the conclusion that a hypothetical association of aGlomus -like fungus with a green alga as a step during the evolution of the land plants appears probable.
