Expression of fruB.Scer\UAS.cUa under the control of Scer\GAL4D42 in either wild-type or frusat females results in the formation of the muscle of Lawrence (MOL) in most of these flies (92% and 91% respectively). Some of these females have one to three MOLs in the A4 and A3 segment in addition to a pair of MOLs in the A5 segment.
fruB.UAS.cUa/Scer\GAL4Toll-6-D42 partially rescues frusat
Expression of fruB.Scer\UAS.cUa under the control of Scer\GAL4D42 rescues the formation of the muscle of Lawrence in at least one side of the A5 segment in 80% of frusat homozygous males.
