Abstract Mini chromosome maintenance 10 (Mcm10) is an essential protein, which is conserved from S. cerevisiae to Drosophila and human, and is required for the initiation of DNA replication. Knockdown of Drosophila Mcm10 (dMcm10) by RNA interference in eye imaginal discs induces abnormal eye morphology (rough eye phenotype), and the number of ommatidia is decreased in adult eyes. We also observed a delay in the S phase and M phase in eye discs of dMcm10 knockdown fly lines. These results show important roles for dMcm10 in the progression of S and M phases. Furthermore, genome damage and apoptosis were induced by dMcm10 knockdown in eye imaginal discs. Surprisingly, when we used deadpan-lacZ and klingon-lacZ enhancer trap lines to monitor the photoreceptor cells in eye discs, knockdown of dMcm10 by the GMR-GAL4 driver reduced the signals of R7 photoreceptor cells. These data suggest an involvement of dMcm10 in R7 cell differentiation. This involvement appears to be independent of the apoptosis induced by dMcm10 knockdown. Together, these results suggest that dMcm10 knockdown has an effect on DNA replication and R7 cell differentiation.
