neurKX9 heterozygotes exhibit learning and 9-minute memory abilities that appear identical to wild-type controls. However, these animals display significantly reduced 260-minute memory.
neurKX9 mutant germline stem cells differentiate and leave the niche, resulting in an empty germarium phenotype when both germline stem cells are mutant.
Hyperplasia of replicating sensory precursors: due to an increased number of ectodermal cells being recruited as sensory precursor cells.
Increase in SMCs per cluster in embryos lacking the maternal product.
