Construct: Expression of a EcoRI-KpnI fragment of lab is driven by an Hsp70 promoter and the Ubx polyadenylation signal phs10.
cephalopharyngeal skeleton
embryonic head
Heat induced expression between 3 and 6 hours of embryogenesis causes a dramatic reduction in the cephalopharyngeal skeleton and a partial block of head involution. Some lethality is seen.
