	WICGR Press Releases -Scientists Publish Draft Sequence and Analysis of Neurospora crassa (Site not responding. Last check: 2007-09-09)
		Neurospora has close fungal relatives that cause animal disease such as athlete's foot and valley fever, or plant diseases that decimate staple crops such as rice, corn, and soy.
		Among the findings in the Neurospora analysis is that the genome encodes about 10,000 protein-coding genes, far less than the estimated 30,000 that humans have, but comparable to that of the fruitfly.
		Neurospora is the flagship of fungal genome sequencing efforts, and the first filamentous fungus to be sequenced.

	Metal transportome of Neurospora crassa
		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).

	Neurospora crassa - Wikipedia, the free encyclopedia
		Neurospora crassa is a type of red bread mold of the phylum Ascomycota.
		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.
		Neurospora was used by Edward Tatum and George Wells Beadle in their experiments for which they won the Nobel Prize in Physiology or Medicine.

		We have demonstrated that G proteins are critical for proliferative growth and differentiation in filamentous fungi, controlling growth rate, asexual sporulation, female fertility and stress tolerance.
