Figure 5: Expression of Z counteracts the overproliferation phenotype within GMR-R eye discs. Third instar eye imaginal discs from wild-type (WT), GMR-R3, GMR-Z, and GMR-R/GMR-Z larvae were stained with anti-phospho-histone-H3 (Ser 10) antibody. The number of positively stained cells within the furrow or posterior to the furrow was counted. Cells from approximately 12 discs were counted for each genotype. Error bars show the standard error; *indicates a P value < 0.0001.
