cDNA construct with homeobox of Antp precisely replaced by the homeobox of Scr, expressed from an Hsp70 promoter.
lethal | heat sensitive
adult head | heat sensitive
antenna | heat sensitive
arista | heat sensitive
embryonic/larval salivary gland | ectopic | embryonic stage | heat sensitive
embryonic head | heat sensitive
eye | heat sensitive
femur | ectopic | heat sensitive
mesothoracic segment | heat sensitive
metathoracic segment | heat sensitive
T1 beard | ectopic | heat sensitive
Heat shock causes failure of head involution and ectopic beards in T2 and T3. Ectopic salivary gland is induced. Adult head shows thickened aristae and second antennal segment transformed into femur, and reduction of eye size.
