Symbiosis in lichens is the mutually beneficial symbiotic relationship of green algae and/or blue-green algae (cyanobacteria) living among filaments of a fungus, forming lichen. [ 1 ] [ 2 ] [ 3 ] Living as a symbiont in a lichen appears to be a successful way for a fungus to derive essential nutrients, as about 20% of all fungal species have ...
Plant and fungal partners within a network may enact a variety of symbiotic relationships. Earliest attention was given to mutualistic networks by which the plant and fungal partners both benefit. [15] Commensal and parasitic relationships are also found in mycorrhizal networks. A single partnership may change between any of the three types at ...
Fungal-bacterial endosymbiosis encompasses the mutualistic relationship between a fungus and intracellular bacteria species residing within the fungus. Many examples of endosymbiotic relationships between bacteria and plants, algae and insects exist and have been well characterized, however fungal-bacteria endosymbiosis has been less well described.
Fungi from Verrucariales also form marine lichens with the brown algae Petroderma maculiforme, [88] and have a symbiotic relationship with seaweed (such as rockweed) and Blidingia minima, where the algae are the dominant components. The fungi is thought to help the rockweeds to resist desiccation when exposed to air. [89] [90] In addition ...
The only known freshwater bivalve with a symbiotic relationship are in the genus Anodonta which hosts the chlorophyte Chlorella in the gills and mantle of the host. [41] In bivalves, photosymbiosis is thought to have evolved twice, in the genus Anodonta and in the family Cardiidae. [ 42 ]
Letharia vulpina, a species of fruticose lichen. A fruticose lichen is a form of lichen fungi that is characterized by a coral-like shrubby or bushy growth structure.It is formed from a symbiotic relationship of a photobiont such as green algae or less commonly cyanobacteria and one, two or more mycobionts.

The exact nature of the relationship between endophytic fungus and host depends on the species involved, and in some cases fungal colonization of plants can bestow a higher resistance against insects, roundworms (nematodes), and bacteria; in the case of grass endophytes the fungal symbiont produces poisonous alkaloids, which can affect the ...
