One copy of tslT:Ivir\HA1 rescues the following defects of embryos from tslΔ mothers: rescues the ventral cuticle hole, but not the "terminal class mutant" phenotype, in late embryos; rescues both the irregularities/gaps of the ventral furrow and the exposure of mesodermal tissue (Twist-positive) at the dorsal surface, but not the elongated ventral furrow or the exposure of pole cells at the dorsal surface, in gastrulating embryos.
Expression of tslT:Ivir\HA1 completely rescues the developmental delay and reduction in size seen in tslΔ mutant flies. The defect in terminal embryonic patterning is not rescued.
