11kb genomic fragment containing the sun, UBL3 and CG15914 transcription units and parts of the Myb and CG8578 transcription units.
Construct: Included within genomic 11.6kb SalI fragment. This fragment includes all Myb coding region, but not 5' non-coding or promoter sequences.
Rescuing activity depends of transcription from a cryptic promoter. Degree of rescue depends on site of insertion of transgene into genome.
