Imprecise excision of P{EP}ballEP863 generates a 1.1kb deletion of the genomic region corresponding to the kinase domain of ball and is therefore considered a kinase-null mutation.
chromosome | third instar larval stage
ballE107 heterozygotes are viable.
ballE107 homozygous third instar larvae display chromosome condensation defects in the mitotic cells in the central nervous system (the same undercondensed chromosome phenotype is observed also in samples treated with colchicine), the frequency of mitotic cells (phospho-histone H3-positive) is significantly decreased compared to wild-type.
ballE107 homozygotes die as early pupae. The mutant larvae grow to the same size as wild-type with no obvious defects in behavior. However, dissection of larvae reveals that the imaginal discs are missing or degenerated and that the CNS is very small. Indeed the number of cells in the larval brain is greatly reduced. Furthermore, dividing cells are almost absent in most of the CNS examined from late third instar larvae. However, in some CNSs that contain mitotic cells, the mitotic chromosomes appear highly overcondensed.
