embryonic salivary gland & epithelial cell
Gli1 mutants exhibit disruption of the paracellular barrier in the embryonic salivary gland. In Gli1 homozygous mutants the adherens junction remains intact, with the regular spacing of plasma membranes maintained. However, the septae normally located between these membranes are reduced in number or absent.
Gli1 in combination with a pair of introgressions from D.simulans spanning 30F1-31E7 to 35D7-36A14 Dsim\Int(2L)S and 21A1 to 22D1--23A2 Dsim\Int(2L)D produces viable flies.
