Special attention has been paid on actinomycetes because they produce various beneficial compounds including antibiotics. Recently, it is revealed that not only morphology but also physiology of actinomycetes are close to those of fungi. Actinomycetes may be a missing link between prokaryotes and eukaryotes. In this paper, some examples exhibiting that actinomycetes are more close to eukaryotes than previously concerned are described based on their secondary metabolites.
