Detailed Description
Statement
Reference

botv423/botv510 animals die as pupae with small eyes and legs. Third instar larvae have smaller discs than the wild type, and in particular, their wing discs are narrower in an anterior-posterior direction. Tissue is deleted within somatic clones of botv510 homozygous cells in the adult wing.

Genetic Interactions
Statement
Reference

Unlike in controls, cytonemes do not cross over ttv524, botv510 double mutant clones at the wing disc anterior compartment abutting the A-P compartment border, except if the cones are very narrow.

The commissural axon phenotype (failure to cross the midline) seen in embryos expressing Sema-1aScer\UAS.cYa under the control of Scer\GAL4P52 in a Sema-1ak13702 null background is not affected if the embryos are also heterozygous for botv510.

Xenogenetic Interactions
Statement
Reference

One copy of botv510 enhances the eye phenotype seen when Hsap\INSC96Y.Scer\UAS is expressed under the control of Scer\GAL4GMR.PF.
