Expression of cad coding region with no 3' region BBR is governed by UAS.
embryonic head, with Scer\GAL4nanos.PG
embryonic head, with Scer\GAL4unspecified
Embryos expressing cadΔBBR.Scer\UAS under the control of Scer\GAL4nos.PG develop head defects.
When expression is driven by Scer\GAL4unspecified throughout the embryo head involution is affected.
