stgBCD partially rescues the clone size of stg2 follicle cell clones; mutant clones half the size of wild-type sister clones are detected. The nuclei of the follicle cells are twice the size of the nuclei of wild-type sister clone cells.
Imaginal disc cells that are homozygous for stg2 divide only once, producing 2-celled clones that are eliminated by cell competition. This phenotype is rescued by stgBCD; stg2 cells in the imaginal disc carrying one of these transgenes divide many times and produce large clones of cells. The clones are smaller than their wild-type sister clones and show increased cell size.
