Mean values and standard deviations (s.d.) of the number of Eve-positive hemisegments are shown for pbl³ homozygous embryos and pbl³ homozygotes expressing wild-type Rho1 protein in the mesoderm using twi::Gal4 (n=number of embryos examined). The crosses employed for this experiment were different from the experiment described in Table 3 and resulted in slightly better rescue of the pbl³ phenotype by Pbl^ΔBRCT (see Materials and methods). The number of Eve-positive hemisegments between pbl³ homozygotes expressing Pbl^ΔBRCT and pbl³ homozygotes expressing Pbl^ΔBRCT and Rho1 was largely unimpaired.
