Wing discs of RYBPKG08683 larvae show similar levels of developmental apoptosis as wild type controls.
RYBPKG08683 embryos display no appreciable changes in cell death throughout the central nervous system during nerve cord condensation in stage 16 embryos or in the embryonic head, compared to controls.
All the phenotypes observed in homozygous embryos, larvae and adults are highly variable both in their penetrance and expressivity and similar results are obtained in RYBPKG08683/Df(2R)58B3-59 animals.
Homozygous animals are sub-lethal and show progressive lethality throughout development. Only 13% of homozygous embryos reach adulthood, with 43% dying during embryogenesis and 44% dying during larval/pupal development.
Homozygous larvae show a significant developmental delay; first instar larvae take 10 days to reach the pupal stage at 25[o]C (compared to 4-5 days for wild-type larvae).
90% of homozygous females are sterile, and in most cases, oogenesis is arrested at stage 8.
Homozygous adults derived from a cross of homozygous females to homozygous males show the same phenotypes as homozygous offspring of heterozygous parents.
Approximately 60% of homozygous embryos die before cuticle formation, showing severe defects in the pattern of nuclear division and of mitotic progression. The nuclear defects are asynchronous and large irregular nuclei are often formed. The remaining approximately 40% of homozygous embryos reach the stage of larval cuticle formation with no detectable cuticle defects.
21% of homozygous adults have a distal gap in the L5 vein, 11% have malformed legs, 54% have umbrella-shaped wings and 5% have 2-3 bristles on the sixth sternite in males. Homozygous flies show a 27% decrease in the size of the wings compared to wild type.
Homozygous embryos show a normal pattern of apoptosis.
Homozygous clones in the wing disc are similar in size to their wild-type twin spots.
Homozygous clones on either the dorsal or ventral adult wing surface result in the appearance of a blister on the opposite surface. The mutant clones show an increase in cell density.
