Photoresponses and Circadian Rhythm

Fungi live in terrestrial habitats. However, because fungi are non-green and their mycelium is generally hidden in substratum, the tendency is to disregard that light has any effect on them. Although generalizations cannot be made, the examples below will show the influence of light on fungal development. The genome analysis of the fungus Neurospora crassa led to unexpected identification of homologues of plant photoresponse proteins such as phytochromes and cryptochrome, sparking interest in the role of light in the development of fungi.
