UAS sequences control expression of Fpps cDNA (amplified with PCR primers: GCTCTAGAGATAGTTACCTGCCGATAATC and CCCTCGAGGTAATTTAGGAGTCACGTTGG)
pole cell & embryonic nervous system, with Scer\GAL4elav-C155
primordial germ cell | embryonic stage 5, with Scer\GAL4Act.PU
In FppsScer\UAS.cSa; Scer\GAL4elav-C155 embryos, small but significant numbers of germ cells migrate into the nervous system.
