The definition of symbiosis was a matter of debate for 130 years. [7] In 1877, Albert Bernhard Frank used the term symbiosis to describe the mutualistic relationship in lichens. [8] [9] In 1878, the German mycologist Heinrich Anton de Bary defined it as "the living together of unlike organisms".
A symbiosome is formed as a result of a complex and coordinated interaction between the symbiont host and the endosymbiont. [5] At the point of entry into a symbiont host cell, part of the cell's membrane envelops the endosymbiont and breaks off into the cytoplasm as a discrete unit, an organelle-like vacuole called the symbiosome.
The symbiosis is rendered more complex than just simple mutualism, both by the physiological discrepancy between language as an overall condition and the nature of individual ideas conveyed through language, as well as by the ecological difference between vertically and horizontally transmitted memes.
There are two major modes of transmission for symbiotic bacteria. The first is horizontal transmission in which microbes are acquired from the environment and either the environment or the host population serves as the inoculum for the symbiosis. [7] An example of horizontal transmission is the deep sea tube worm and its symbiont. [7]
The concept of a consortium was first introduced by Johannes Reinke in 1872, [4] [5] and in 1877 the term symbiosis was introduced and later expanded on. Evidence for symbiosis between microbes strongly suggests it to have been a necessary precursor of the evolution of land plants and for their transition from algal communities in the sea to land.

These new ideas can be studied today under the title of the Theory of Endosymbiosis. [ 20 ] Despite the above studies the dual nature of lichens remained no more than a theory until in 1939 the Swiss researcher Eugen A Thomas [ 21 ] was able to reproduce in the laboratory the phenotype of the lichen Cladonia pyxidata [ 22 ] by combining its two ...
