Deletion of 41,681 bp ( 2R:16 ,689,713 to 16,731,394) corresponding to exons 1-4 of Pgant9.
Scer\FRT-mediated recombination between the two progenitor insertions PBac{WH}Pgant9f03628 and P{XP}Pgant9d11168 has resulted in the deletion of the 41,682bp of genomic sequence between them.
The larval salivary glands of Pgant9Δ/Df(2R)Exel6064 transheterozygotes exhibit secretory granules that are irregular in size and shape, with an angular or shard-like appearance; these defects are not observed in immature granules (i.e. <1 μm).
