The genome sequence of the filamentous fungus Neurospora crassa

Article Abstract:

Neurospora possesses the widest array of genome defence mechanisms including a process unique to fungi called repeat-induced point mutation (RIP). Genome analysis suggests that RIP has had a profound impact on genome evolution, thus slowing down the process of the creation of new genes through genome duplication and resulting in a genome with an unusually low proportion of closely related genes.

The methylated component of the Neurospora crassa genome

Article Abstract:

Methyl-binding-domain agarose chromatography is used to isolate the methylated component of the Neurospora crassa genome. The DNA sequence analysis shows that the methylated component of the genome consists almost exclusively of relics of transposons that were subject to repeat-induced point mutation, which is a genome defence system that mutates duplicated sequences.

Revelations from a bread mould

Article Abstract:

The filamentous fungus Neurospora crassa is an organism much loved by geneticists. Its genome sequence has now been unveiled, and includes a relatively high number of genes.
