αTub84B promoter sequences drive expression of shg coding sequences where four Y residues have been converted to F (amino acid replacements Y1372F, Y1447F, Y1473F and Y1488F).
shg4YF.Tub84B.PP rescues shgR69
The presence of shg4YF.Tub84B.PP rescues all shgR69 phenotypes during oogenesis as well as lethality caused by a lack of endogenous shg in the embryo.
