    Description

    Df(3L)h9 removes the 3' end of JIL-1, removing sequences beyond nucleotide 3398 of JIL-1. This results in an in-frame stop codon after amino acid 795.

    Deletion removes the C-terminal protein sequence.

    JIL-1z2/JIL-1h9 mutants the morphology of the polytene chromosomes is perturbed with coiled and compacted chromosome arms. The male X polytene chromosome shows the most extreme version of this phenotype with no coherent bands visible.

    0% of embryos derived from JIL-1z2/JIL-1h9 females mated to wild-type males hatch. Heterozygous ovaries are indistinguishable from wild-type in size. JIL-1z2/JIL-1h9 animals that survive to adulthood are sterile and females produce significantly fewer eggs than normal. JIL-1z2/JIL-1h9 ovaries are significantly decreased in size compared to wild type, consisting primarily of connective tissue with little or no apparent ovariole development, although in some cases ovary tissue develops to some degree. In those females with some ovary development, a range of egg chamber defects are seen. The most common consists of egg chambers with a reduction in the number of nurse cells and no apparent oocyte nucleus. In other cases cell nuclei within the egg chamber appear to fragment of fail to undergo DNA amplification. In a few cases, egg chambers containing an increased number of nurse cells are seen. In all cases, other ovarioles in the same ovary often appear empty with no egg chamber development.

    General trend from least to most viable is: JIL-1z2 < JIL-1h9 < JIL-1z60 < JIL-1EP3657 < JIL-1z28 ~ JIL-1Scim.
