| Dataset |
A set of transgenic insertion stocks derived by TE mobilization using the Tni\piggyBac-based construct PBac{PB}. The PBac{PB} construct carries the w[+mC] mini-white marker flanked by short (48-bp) Scer\FRT recombination sites.
PBac{PB} insertion lines from Exelixis were remapped and assessed for inclusion in the Gene Disruption Project collection; flanking
sequence data were submitted to GenBank.

Statement
Reference
Expression of CHORD[Scer\UAS.cFa] under the control of Scer\GAL4[Act5C.PI] in CHORD[c02881] mutant animals fails to rescue lethality.
CHORD[c02881]/+ flies are viable and morphologically normal.
CHORD[c02881]/CHORD[c02881] flies die as third instar larvae. Mutant larvae are devoid of imaginal discs, and display strongly reduced testes and salivary
glands.
Brain preparations from CHORD[c02881] mutant larvae show that in 95% of dividing cells the chromosomes are elongated and irregularly condensed. Mutant cells spend
more time in mitosis than wild-type control cells. The majority of cells remain arrested in a prophase-metaphase state.
Of those that do escape into anaphase, strong defects in chromosome segregation are observed. 30% of mutant neuroblasts
are polyploid, compared to 0.2% in control cells. In addition, an increase in the frequency of apoptotic cells is observed
in mutant tissue (7.7%) compared to control brain tissue (0.5%).
Supernumerary centrosomes are observed in CHORD[c02881] mutant brain cells.
Expression of Hsap\CHORDC1[Scer\UAS.cFa] under the control of Scer\GAL4[Act5C.PI] in CHORD[c02881] mutant flies rescues the imaginal disc and testis phenotype, and these tissues appear mostly normal. Most mitotic divisions
observed in brain tissue are completely normal None of the observed mitotic figures were polyploid, and 98% of dividing
cells display two centrosomes. These flies still die during metamorphosis.
