Polytene chromosomes normal.
Small deletion that removes most of the 3' coding exon of dpp (St. Johnston, EMBO J. 6: 2785--2791).
embryo (with Df(2L)DTD48)
Homozygous embryos have a fully ventralised cuticle with a herniated head, ectopic denticle belt replacing the Filzkorper and ventral denticle belts encircling the body.
Clones in the eye imaginal disc cause a reduction in the size of the eye. Clones in the anterior of the eye completely devoid of dpp (haploinsufficiency is circumvented by using an FRT chromosome containing on the left arm dppH61 and on the right arm dppSal20) display normal ommatidia throughout the entire clone.
Denticle belts extend around the entire circumference of homozygous embryos.
Fail to complete germ band extension, die with strong ventralized phenotype and no dorsal derived epidermis.
Df(2L)DTD48/dppH61 has embryo phenotype, suppressible by dpp::Hsap\BMP4fl.cPa
dppH61 is a suppressor of macrochaeta | ectopic | somatic clone | cell non-autonomous phenotype of Pka-C1E95
dppH61 is a suppressor of wing | somatic clone phenotype of Pka-C1H2
dppH61 is a suppressor of scutum | somatic clone phenotype of Pka-C1H2
dppH61 is a suppressor of haltere | somatic clone phenotype of Pka-C1H2
dppH61 is a suppressor of antenna | somatic clone phenotype of Pka-C1H2
dppH61 is a suppressor of leg | somatic clone phenotype of Pka-C1H2
Clones double mutant for dppH61 Pka-C1E95 do not cause supernumerary structures in the leg and wing. Clones positioned at the compartment boundary exhibit long range effects causing a marked reduction in wing size and loss of vein pattern in anterior and posterior compartments. Short range effects include inducing immediate neighbours to form ectopic veins and margin bristles, the clones fail to differentiate wing veins in a cell autonomous fashion.
Suppresses the majority of pattern defects caused by Pka-C1H2 clones in the wing, notum, halteres and antennae and partially suppresses defects in the ventral regions of the leg.
Three copies of dpp::Hsap\BMP4fl.cPa fully rescues the embryonic phenotype of dppH61/Df(2L)DTD48.
Df(2L)DTD48/dppH61 is rescued by dppP23
Two copies of dppP23 completely rescues the embryonic dorsal-ventral patterning defect of null dppH61/Df(2L)DTD48 genotype.
Mutant phenotype rescued by P element mediated transformation of a wild type copy of dpp.
