Diagram of the six possible types of symbiotic relationship, from mutual benefit to mutual harm. 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.
Co-evolution is described as a situation where two organisms evolve in response to one another. In a study reported in Functional Ecology, [11] these scientists investigated whether such a mutualistic relationship conferred an evolutionary advantage to either plant or symbiont. They did not find that the rhizobial bacteria studied had any ...
Symbiont transmission is the process where the host acquires its symbiont. Since symbionts are not produced by host cells, they must find their own way to reproduce and populate daughter cells as host cells divide. Horizontal, vertical, and mixed-mode (hybrid of horizonal and vertical) transmission are the three paths for symbiont transfer.
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.
Mixotricha paradoxa, which itself is a symbiont, contains numerous endosymbiotic bacteria; Parakaryon myojinensis, a possible result of endosymbiosis independent of eukaryotes; Parasite Eve, fiction about endosymbiosis; Strigomonas culicis, another protozoan that harbours an obligate bacterial symbiont
The term mutualism was introduced by Pierre-Joseph van Beneden in his 1876 book Animal Parasites and Messmates to mean "mutual aid among species". [ 4 ] [ 5 ] Mutualism is often conflated with two other types of ecological phenomena: cooperation and symbiosis .
