      Additional Information
      Statement
      Reference

      In third instar eye disc, expressed in all photoreceptors.

      (Treisman and Rubin, 1996)

      Strong EcollacZ expression is observedin R3 and R4. Weak expression is seen in R1, R2, and R5-R8. In a romutant background, early R3 and R4 expression is missing.
