摘要

虽然大多数真核生物都有MSH4和MSH5同源物,但神经孢子虫最初被认为缺乏msh-4。我们已经删除了最有可能的msh-4候选者,并观察到性周期延迟,减数分裂中断和生育能力降低。缺失是显性的,表明msh-4受MSUD影响。我们得出结论,神经孢子菌具有MSH4同源物,并且由于内含子数量异常高,它可能未被检测到。本作品采用知识共享署名-相同方式共享4.0许可协议。这篇常规论文可在真菌遗传学报告:http://newprairiepress.org/fgr/vol53/iss1/2

Neurospora msh4 ortholog confirmed by split-marker deletion
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.
