Schematic representation of the basis for the genetic screen used to isolate mutants that are synthetically lethal in the absence of CLA4. Xi (activator of STE20), Xii (component of a non-STE20-related pathway), and Yi (target of STE20) represent classes of mutants that are hypothesized to be recovered by the genetic screen.
