20kb fragment including the dpp transcription unit and surrounding regulatory sequences.
dpp rescue construct: fragment of dpp from coordinates 71.2 to 92 of dpp region, i.e. missing 5' most alternative non-coding exon, but including sequences from the shv region of dpp.
report comment: Covers all functions mediated by the dpp-Hin and dpp-shv regions, but fails to rescue appendage defects related to imaginal disc A/P boundary functions.
