Additional Information
Statement
Reference

Expression pattern in syncytial and cellular blastoderms is observed to be nearly identical to that of endogenous toll, although expression levels are observed to be lower. The level of expression in the posterior cap is lower than that seen in EcollacZtll.S2.hsRA.
