lidk06801 mutants are near lethal and the few escapers are morphological normal but short-lived.

lid10424/lidk06801;lidJmjC.T:Ivir\HA1 'rescue' flies display premature transcriptional reactivation as well as precocious karyosome remodeling (the oocytes display early increase in chromatin openness) in prophase I-arrested oocytes and the eggs show impaired entry into embryogenesis after fertilization resulting in strongly reduced female fertility.

lidk06801/lid10424 mutant female germlines exhibit abnormal morphology of the karyosome, defective clustering of centromeres, and a failure to maintain the synaptonemal complex.

lidk06801/lid10424 mutant flies have irregularly shaped mitochondria that are larger than those of wild-type flies and the flies display reduced climbing ability.

lidk06801 homozygotes survive at less than 5% rate, whereas about 50% of lidk06801/lid10424 mutants survive.

lidk06801 mutant flies rescued with any of the following: lidgWT, lidgJmjC.mut or lidW1771A do not show any mitochondrial abnormalities in the thoracic muscles.

The percentage of testes with at least one lidk06801/lidk06801 germline stem cell clone declines over time compared to wild type.

Homozygotes reach pupal development at 71% of expected frequency, but only 0.5% of the expected number of homozygotes survive to adulthood.

lidk06801/lid10424 animals eclose at approximately half the expected frequency.

Some lidk06801/lid10424 flies appear to die before hatching, although no obvious defects in the larval cuticle are seen.

Reference

lidk06801 Kdm2DG12810 double homozygotes show enhanced lethality compared to either single mutant, dying during the first and second larval instar stages.

The small, rough eye phenotype caused by expression of asf1Scer\UAS.cMa under the control of Scer\GAL4ey.PH is significantly suppressed by lidk06801/+.

The thickening of the wing veins that is seen in N55e11/+ flies is suppressed by lidk06801/+.

The truncation of wing vein L5 that is seen in HP141/+ heterozygotes is enhanced by lidk06801/+.

The dmP0 ; lidk06801/lid10424 combination results in almost complete lethality.

Double heterozygotes with ash122, brm2 or trxB11 show T3 to T2 transformations. The ectopic sex comb teeth seen on the second leg of Df(3L)Pc heterozygotes are partially suppressed by one copy of lidk06801.

The premature transcriptional reactivation as well as precocious karyosome remodeling (the oocytes display early increase in chromatin openness) in prophase I-arrested lid10424/lidk06801 transheterozygous oocytes is rescued by combination with lidT:Ivir\HA1.
