Neurospora msh4 ortholog confirmed by split-marker deletion

Abstract

Although most eukaryotes have both MSH4 and MSH5 orthologs, Neurospora was initially thought to lack msh-4. We have deleted the most likely msh-4 candidate and observed a delay in the sexual cycle, disruption to meiosis and a reduction in fertility. Deletion is dominant, showing msh-4 is subject to MSUD. We conclude that Neurospora has a MSH4 ortholog and that it may have remained undetected because of an unusually high number of introns.
