FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
pblunspecified mutant embryos form a faint ball of cuticle. Mitosis is defective, resulting in fewer and much larger cells than normal in late embryos.
pblunspecified has mesoderm phenotype, non-suppressible by Rho1V14.UAS/Scer\GAL4twi.PB
Rho1V14.Scer\UAS with Scer\GAL4twi.PB does not rescue the defects in mesodermal migration see in pblunspecified homozygous embryos.
pblunspecified is rescued by Scer\GAL4unspecified/pblUAS.GFP
Expression of pblScer\UAS.T:Avic\GFP driven by Scer\GAL4unspecified rescues the pblunspecified cytokinetic phenotype.
