Member of Large Scale Dataset(s)

Insertion lines from this collection were assessed for inclusion in the Gene Disruption Project collection.

A set of mutant stocks derived by insertional mutagenesis using the P-element construct P{PZ}; most lines have a lethal or sterile phenotype. The P{PZ} construct carries a ry[+] visible marker, Ecol\lacZ enhancer trap sequences, and bacterial sequences that allow plasmid rescue.

Additional Information

dpp reporter is barely expressed in anterior and posterior dorsal nests histoblasts at 4-6h APF and not at all in surrounding LECs. Only a small group of cells in the ventral nest begin to express at this stage. During the onset of histoblast expansion (16-17h APF), dpp-LacZ is expressed in discrete dorsal cells from the anterior dorsal and ventral nest. In addition, dpp reporter is upregulated in most larval epidermal cells surrounding each of the four nests.

In addtion to expression anterior to and close to the A/P boundary of third instar wing discs, dpp reporter expression is observed in a proximal region of the posterior compartment beginning in the mid-third-instar larval stage. In the adult wing, staining is observed along the A/P border and in the axillary cord but not in the alula.

dppFBtr0091350:pb-XREcol\lacZexpression pattern in the wing disc is restricted to a stripe of cells alongthe antrior-posterior compartment boundary.

In embryo, expression in anterior spiracles and in PNS not certain.
