A detailed analysis of cell-to-cell interactions between host and mycobiont identifies the cell walls, membranes, and cytoskeleton of both partners as the structures where crucial changes occur (Bonfante, 2001).
In its possession of a hyaline, highly characteristic fungal component (the mycobiont) to which cyanobacteria are attached, C.
As is well known, the lichen symbiosis consists essentially of a fungus, the mycobiont, and an alga, the photosymbiont.
Lichens, symbiotic associations of an alga (the phycobiont) and a fungus (the mycobiont), can generate a wide range of phenolic substances, mostly depsides and depsidones.
Parietinwas secreted by mycobiont absorbs blue light and provides protection to photobiont against drastic sun rays (Gauslaa and McEvoy, 2005).
Lichens are a symbiotic association of algae (phycobiont) and fungi (mycobiont), and are long lived, growing on rock, wood, or soil substrates.
Since the mycobiont is unique in the symbiotic association and usually dominates the association, lichens are traditionally classified as a lifeform of fungi.
Lichens are composite organisms consisting of a symbiotic association between a fungal partner (mycobiont) and one or more photosynthetic partners (photobiont) usually either green algae or cyanobacterium or both.
Lichens are generally defined as symbiotic organisms resulting from the successful association between a fungus (the mycobiont) and an extracellularly located photosynthetic partner (the photobiont), which in most cases is represented by green algae, but it can also be replaced by cyanobacteria (10% of lichen symbiosis) or by the simultaneous association of both algae and cyanobacteria (3-4%) [1].
Lichens are symbiotic organisms of photobiont and mycobiont. The photobiont provides the living space and nutrition for endolichenic fungi; in return, the endolichenic fungi might produce some secondary metabolites to help its host defend bio/abioattacks [6].
Lichen is a symbiotic association between two different organisms; one is the alga (Photobiont) another is fungus (Mycobiont).
Lichens are in fact an ecosystem comprising of a photobiont that can either be a green alga (Chlorophyta) or a cyanobacterium and a mycobiont that in most cases belongs to the Ascomycetes.
