      The sextuple co-expression of Gr32aUAS.cSa, Gr33aUAS.cMa, Gr39aUAS.a.cSa, Gr59cUAS.cUa, Gr66aUAS.Tag:MYC and Gr89aUAS.cSa under the control of Scer\GAL4Gr64f.9.7 makes L-type sensilla responsive to the bitter chemicals LOB, BER, and DEN, but not to the bitter chemicals CAF, STR, SOA or UMB. Control L-type sensilla, however, are only responsive to sucrose; this sextuple co-expression has no effect on the normal response to sucrose.

      Only quintuple co-expression combinations that include Gr32aUAS.cSa, Gr59cUAS.cUa and Gr66aUAS.Tag:MYC induce responsiveness of L-type sensilla to LOB, BER, and DEN. In agreement, the triple co-expression of Gr32aUAS.cSa, Gr59cUAS.cUa and Gr66aUAS.Tag:MYC is sufficient to induce responsiveness to LOB, BER, and DEN, but not to CAF, STR, SOA, or UMP, whereas all double combinations of these three do not. All mentioned quintuple, triple and double co-expression have no effect on the normal response to sucrose.

      L-type sensilla co-expressing Gr32aUAS.cSa, Gr59cUAS.cUa and Gr66aUAS.Tag:MYC under the control of Scer\GAL4Gr64f.9.7 show the expected responsiveness to sucrose and ectopic responsiveness to the bitter chemicals LOB, BER and DEN. Df(3L)ΔGr64af abolishes the expected responsiveness to sucrose, but not the bitter chemicals.

      The triple co-expression of Gr32aUAS.cSa, Gr66aUAS.Tag:MYC and Gr22eUAS.cSa under the control of Scer\GAL4Gr64f.9.7 makes L-type sensilla responsive to the bitter chemicals LOB, BER, DEN, STR and UMB, but not to CAF or SOA, while not affecting the normal response to sucrose. Df(3L)ΔGr64af abolishes the responsiveness to sucrose, reduces the ectopic responsiveness to STR, but has no effect on the ectopic responsiveness to LOB, BER and DEN.

      The triple co-expression of Gr32aUAS.cSa, Gr66aUAS.Tag:MYC and either Gr22fUAS.cSa or Gr39bUAS.cSa under the control of Scer\GAL4Gr64f.9.7 does not confer responsiveness of L-type sensilla to the bitter chemicals LOB, BER or DEN.
