bacteria has existed for millennia. EPNs are found in terrestrial environments, including deserts, rainforests, grasslands and other ecological systems, offering a tremendous array of possibilities for study. Stock, who has been researching and inter...
Fungus-farming termites descend from an African rain forest Eve

symbiosis. The termites use chewed plant material,... savannas. The marrying of termites and fungi in a mutualistic
symbiosis has thus allowed both partners to conquer the savannah: agricultural termites and their mu...

Study reveals classic symbiotic relationship between ants, bacteria
...lustrates the intricate and ancient nature of this mutualistic
relationship. The researchers found that the ants house the bacteria in specialized, highly adapted cavities and nourish them with glandular secretions-an indication that the ants, bacteria, fungus and parasites have likely been evolving together fo...

Symbiotic fungus does not depend on fungus-farming ants for reproduction, researchers say
... level," said Mikheyev. "It has been believed that mutualistic
interactions, as well as parasitic ones, are very specific and one-to-one. We are beginning to realize that this is not necessary for long-term coevolutionary stability, with the leaf-cutting ants being a dramatic example." The research was publis...
DOE JGI sequences, releases genome of symbiotic tree fungus
...ots, a mycorrhizal root is created, resulting in a mutualistic
relationship that significantly benefits both organisms. The fungus within the root is protected from competition with other soil microbes and gains preferential access to carbohydrates within the plant. Such mycorrhizae are critical to terrestrial...
Discovery about evolution of fungi has implications for humans, says U of M researcher
