Detailed Description

Reference

Microchaetae are reduced in size in mutant clones in the thorax.

Mutant embryos have essentially naked cuticle. Expression of ovo+2b.Scer\UAS under the control of Scer\GAL4ptc-559.1 in ovosvb-1 embryos rescues denticle rows 2 and 3 and also induces a stripe of ectopic denticles. Expression of ovo-2b.Scer\UAS under the control of Scer\GAL4ptc-559.1 in ovosvb-1 embryos rescues denticle rows 2 and 3 and also induces a stripe of ectopic denticles.

Hemizygous embryos have a naked cuticle phenotype.

Fails to complement the Dsec\ovo in D.melanogaster/D.sechellia hybrids.

ovosvb-1 embryos present almost exclusively naked cuticle, with only sparse atrophied denticles in the posterior-most rows of each belt.

ovo, svb phenotype.

Phenotypic category: ovo-.

Gene activity not detectable. Female germ line has no vitellogenic egg chambers.

There are many fewer denticles than in the wild-type larva. The remaining denticles are small and have characteristic morphology. They are arranged in "belts", with one belt per abdominal segment. The hairs and unpigmented denticles normally found on the dorsal surface of the larva are almost completely eliminated. Hemizygous males are fertile but show reduced adult viability and slight abnormalities in the sternopleural bristles and sex combs. Homozygous females are poorly fertile.
