Using a selection forDictyosteliummutants that preferentially form spores, we have recovered a mutant calledCheaterA.In chimeras with isogenic wild-type cells, theCheaterAmutant preferentially forms viable spores rather than inviable stalk cells. The mutant causes wild-type cells that have begun to express spore-specific genes to accumulate in the prestalk compartment of the developing organism. In the wild-type cells, thechtAtranscript is absent in growing cells and appears early in development. No transcript was detected in the mutant by Northern blot. ThechtAgene codes for a protein with an F-box and WD40 domains. This class of protein usually forms part of anSkp1,cullin,F-box (SCF) complex that targets specific protein substrates for ubiquitination and degradation.
