The FRT cassette containing the QF driver coding sequence has been excised from P{alrm(FRT.QF)GAL4}, generating P{alrm(-FRT)GAL4}, which expresses a GAL4 driver under the control of the alrm promoter sequences.
The Scer\FRT cassette containing the Ncra\QF coding region has been excised from P{alrm(FRT.QF)GAL4}, generating P{alrm(-FRT)GAL4}, which expresses Scer\GAL4 under the control of the alrm promoter sequences.
