EIF4E3 and cyst: Knockdown of eIF4G2 using nos-Gal4:VP16 did not appear to affect the distribution of eIF4E-3 or spermatocyte cyst development (compare Fig 6A with 6B), but the elongated spermatids in the late stages of differentiation that encompass the length of the wild-type testes were absent (compare Fig 6A' and 6C' with 6B' and 6D').
