Neurospora crassa is a red mold from the department of hose mushrooms (Ascomycota).

It is a well-known model organism in biology that is easy to grow. It has a haplontic life cycle that allows easy genetic analysis. Neurospora was chosen as the subject of study by Edward Tatum and George Wells Beadle . In 1958 they received the Nobel Prize for their work . They exposed the mold to ionizing radiation to trigger mutations . They then examined the metabolic pathways for defects in enzyme activities . From their observations, they derived the one-gene-one-enzyme hypothesis , which is only valid to a limited extent today.

In April 2003 the genome of N. crassa was published as sequenced in Nature . It is around 43 megabases and contains around 10,000 genes .

The fungus occurs naturally mainly in the tropical and subtropical regions and predominantly on decaying plant material. Similar to the bacterium Serratia marcescens , it may also thrive on hosts and can discolor them red and thus give the wrong impression of a host miracle .

Systematics

N. crassa serves as a representative for the clade around the taxon of the Nucletmycea .
