A nonhomologous end-joining mutant for Neurospora sitophila research

Abstract

Disruption of the nonhomologous end-joining (NHEJ) pathway has been shown to increase the efficiency of transgene integration into targeted genomic locations of Neurospora crassa and other fungi. Here, we report that a similar phenomenon occurs in a second Neurospora species: N. sitophila. Specifically, we show that deletion of N. sitophila mus-51 increases the efficiency of targeted-transgene integration, presumably by disrupting NHEJ. Researchers interested in obtaining the N. sitophila mus-51{Delta} strains described in this study can obtain them from the Fungal Genetics Stock Center (FGSC).
