“The filamentous mould Rhizopus microsporus is a member of the zygomycetes (lower fungi). While some strains serve as food fermenting fungi, others represent infamous plant pathogens and opportunistic human pathogens. Recently, it was shown that some strains of R. microsporus are associated with symbiotic bacteria. Here, we outline why these organisms are important for human health and how they can be exploited for drug development. Furthermore, we illustrate what the investigation of bacterial–fungal symbiosis can teach us about the evolution of pathogenicity factors in general.”
Endosymbiont bacteria in a fungus? That’s so cool. And this review (link below) talks about the impact of this endosymbiont in various areas. It also goes into the biology of symbiosis. Quite fascinating. Read it.
