A heat shock promoter drives expression of αftz-f1.
ftz-f1α.hs, ftz-f1ex7 has embryonic/first instar larval cuticle phenotype, suppressible by ftzhs.PSb
ftz-f1α.hs, ftz-f1ex7 has embryonic epidermis phenotype, suppressible by ftzhs.PSb
The cuticle phenotype of ftz-f1 mutants is rescued by heatshock expression of ftz-f1α.hs.
