UAS regulatory sequences drive expression of a short inverted repeat.
Expression of Cdc7GL00585 under the control of Scer\GAL4VP16.mat.αTub67C in the mother results in multiple unevenly-distributed, highly fragmented DNA masses in the embryo interior, along with scattered abnormal mitotic structures; nuclei fail to form a blastoderm, but centrosomes often continue to duplicate in the absence of any associated DNA.
Females heterozygous for Cdc7GL00585 and MTD-Gal4 (consists of Scer\GAL4otu.T:Hsim\VP16, Scer\GAL4nos.PG and Scer\GAL4nos.UTR.T:Hsim\VP16) crossed to Cdc7GL00585 males results in: 20% hatching; egg/embryonic phenotype: "empty, all white"; maternal effect.
Cdc7GL00585, Scer\GAL4VP16.mat.αTub67C has majority die during embryonic stage | maternal effect phenotype, suppressible | maternal effect | partially by Rif1KO/Rif1KO
Cdc7GL00585, Scer\GAL4VP16.mat.αTub67C has abnormal mitotic cell cycle | maternal effect | embryonic stage phenotype, suppressible | maternal effect | partially by Rif1KO/Rif1KO
Cdc7GL00585/Scer\GAL4VP16.mat.αTub67C is an enhancer | maternal effect of some die during embryonic stage | maternal effect phenotype of Rif1KO
Cdc7GL00585, Scer\GAL4VP16.mat.αTub67C has nucleus | maternal effect | embryonic stage phenotype, suppressible | maternal effect | partially by Rif1KO/Rif1KO
Rif1KO homozygosity, but not heterozygosity in mothers expressing Cdc7GL00585 under the control of Scer\GAL4VP16.mat.αTub67C restores cell cycle progression, with most embryos reaching the blastoderm stage; nuclear abnormalities still occur, but some embryos (a minority) survive and hatch.
