Klp61F07012/Klp61F06836 trans-heterozygotes display larval lethality.

Klp61FUbi-p63E.T:Avic\GFP rescues the lethality of trans-heterozygous Klp61F07012/Klp61F06836 mutants. The rescued flies are fertile and can be propagated as stable transgenic lines. The rescued embryos display a decrease in the rate of prometaphase-to-metaphase spindle elongation compared with wild type embryos, which leads to a small decrease in subsequent spindle length.

The brains of homozygous larvae have a reduced frequency of anaphase figures, and an increased frequency of polyploid figures and overcondensed chromosomes compared to wild-type. The brains and imaginal discs are approximately half normal size.

Homozygotes and hemizygotes die as late third instar larvae or early pupae. Neuroblasts isolated from third instar homozygous larvae show an increased mitotic index and complete lack of anaphase figures, indicating metaphase arrest. Chromosomes are hypercondensed compared to wild-type and highly polyploid cells are common.

Comments

Excision of the P{PZ} element is accompanied by reversion of lethality and the abnormal mitotic phenotype.

Klp61F alleles form the following phenotypic series, from the most to the least severe: Klp61Furc-1 > Klp61Furc-3 > Klp61F06836, Klp61F07012 > Klp61F06345 > Klp61Furc-4.
