Construct: B-H2 minigene is fused to heat shock promoter.
microchaeta & head capsule & adult
scutellum & microchaeta
wing & microchaeta
Heat-induced expression during larval or pupal development can generate ectopic microchaetae in the scutellum, wing blades and head capsule. Extra microchaetae were unclustered.
Overexpression of B-H2 causes almost complete conversion of trichoid to campaniform-like sensilla, this does not require endogenous B-H2.
