Polytene chromosomes normal.
Deletion of 4845bp, including the 812bp regulatory region that directs expression in parasegment 7 of the visceral mesoderm.
Deletion within shv region.

Abnormal gut morphology.
Fails to form second midgut constriction. Length of midgut reduced in section 2, with remaining cells having hexagonal shape. Small but statistically significant decrease in the viability of adults.

dpps6/dpphr4 has wing vein L5 phenotype, enhanceable by Med7
dpps6/dpphr4 has wing vein L4 phenotype, enhanceable by Med7
dpps6/dpphr4 has wing vein L5 phenotype, enhanceable by Df(2L)C28/+
dpps6/dpphr4 has wing vein L4 phenotype, enhanceable by Df(2L)C28/+
dpps6/dpphr4 has wing vein L5 phenotype, enhanceable by Df(3R)E40/+
dpps6 has wing vein phenotype, enhanceable by Df(2R)Pcl11B/+
dpps6 has wing vein phenotype, enhanceable by Df(2R)Pcl7B/+
Df(2L)C28/+, dpps6/dpphr4 has wing vein L2 phenotype
Df(2L)C28/+, dpps6/dpphr4 has posterior crossvein phenotype
dpps6/dpphr4 Mad1 flies exhibit L4 and L5 wing vein defects in almost 100% of cases. Approximately 10% of wings with L4 and L5 defects exhibit missing crossveins (anterior, posterior, or both) and small wing margin notches. This indicates an enhancement of the dpps6/dpphr4 phenotype by Mad1.
Only 71% of the expected dpps6/dpphr4 Mad1 progeny are recovered, indicating a statistically significant amount of lethality.
dpps6/dpphr4 Med7 flies exhibit L4 and L5 wing vein defects in approximately 42% of cases, with 15% of these wings also exhibiting defects in L2, or the posterior crossvein or margin notches.
The incidence of abnormal venation in dpphr4/dpps6 is increased by Df(2R)Pcl11B or Df(2R)Pcl7B.
Df(2L)DTD2/dpps6 is rescued by dppSal20
dpps-hc1 and dppTgR46.1 each fully complement the wing vein defects of dpps6.
Allele class: shv-w
Used to examine regulation of dpp-Ecol\lacZ promoter fusions, whose expression depends on endogenous dpp function demonstrating that positiveautoregulation maintains dpp expression in the visceral mesoderm.
