Cytology
Description

Contains a 2.2kb ClaI genomic fragment including the E(spl)m8-HLH1 deletion allele. Nine amino acids are added on the end of the open reading frame as a consequence of the frame shift caused by the deletion.

      Reference

      E(spl)m8-HLH1.tNa is an enhancer of eye phenotype of Nspl-1

      Statement
      Reference

      Addition of E(spl)1.tNa to Nspl-1 flies enhances the "split" eye phenotype, in a manner indistinguishable from E(spl)::HLHmδcNa and which phenocopies E(spl)1. A substantial reduction is seen in the number of ommatidia and an increase in cell death, as concluded from the characteristic "blueberry" phenotype.
