N. crassa is notable for its use as a model organism in science because it is easy to grow and has a haploid life cycle that makes genetic analysis simple since recessive traits will show up in the offspring. Its entire genome of seven chromosomes has been sequenced [1]. Neurospora was used by Edward Tatum and George Wells Beadle in their experiments for which they won the Nobel Prize in Physiology or Medicine. Beadle and Tatum exposed N. crassa to x-rays, causing mutations. They then observed failures in metabolic pathways caused by errors in specific enzymes. This led to the "one gene, one enzyme" hypothesis that states that specific genes code for specific proteins. A model organism is a species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms. ...

In the 24 April 2003 issue of Nature, the genome of N. crassa was reported as completely sequenced. The genome is about 43 megabases long and includes approximately 10,000 genes. Currently there is a project underway to produce mutant knockouts for every gene in the genome of N. crassa. These mutants are provided at an extremely low price in return for any research information gathered on them. First title page, November 4, 1869 Nature is one of the oldest and most reputable scientific journals, first published on 4 November 1869. ...

DNA sequencing is the process of determining the nucleotide order of a given DNA fragment, called the DNA sequence. ...


In its natural environment, N. crassa lives mainly in tropical and sub-tropical regions. It can be found growing on dead plant matter after fires.

Metal transportome of Neurospora crassa (3893 words)
Neurospora crassa has been the model filamentous fungus for the study of many fundamental cellular mechanisms of transport and metabolism.
Neurospora crassa is a multicellular filamentous fungus playing central role as model organism in the history of twentieth century genetics, biochemistry and molecular biology.
Knockout mutants of Neurospora crassa would be useful in characterization of metal ion transporters and the recent Neurospora genome project initiative directed towards the above is in active progress (http://www.dartmouth.edu/~neurosporagenome/1_s1.html).
