Description

Imprecise excision of the P{SUPor-P}KG04817 element, resulting in a deletion extending from 1011bp upstream of the start of the CycD coding region to 892bp downstream of the start of the CycD coding region. 29bp of residual P-element sequences remain.

Detailed Description
Statement
Reference

Mutant flies show a reduction in body weight and show a reduction in wing size compared to wild type-controls.

The fertility of homozygous females and hemizygous males is severely reduced, although a few adult progeny can be obtained from mutant parents. Hemizygous adult males weigh on average only 85% of the weight of control males. The average wing area of hemizygous males is only 88% that of wild type and the number of cells in the wing is 85% that of wild type. The cells in the wing of hemizygous males are slightly increased compared to wild type. Homozygous clones in the wing induced approximately 60 hours after egg laying and allowed to develop for a further 60 hours cover only about 50% of the area of the control sister clones. There is no increase in the number of apoptotic cells associated with the mutant clones, and the mutant cells show no significant differences in cell size or cell-cycle phasing compared to control cells. Endoreduplication is not initiated on time in the central domain of the midgut in mutant embryos, and is inefficient and not completed on time within the anterior and posterior midgut domains.
