Molecular characterization of required for killing-2: a gene required for spore killing by Neurospora Sk-3.
The Sk-3 selfish genetic element in Neurospora fungi is transmitted to offspring in a biased manner through spore killing. In crosses between an Sk-3 strain and a Spore killing-sensitive (Sk-S) strain, nearly all offspring that fail to inherit Sk-3 are killed. Although a mutation called rfk-2UV, which disrupts spore killing by Sk-3, was isolated in an earlier work, its precise location within the…
