FlyBase curator comment: this entry represents a transgenic construct where the particular construct used cannot be determined.
The expression of Gr59cUAS.cUa under the control of Scer\GAL4Gr64f.9.7 is not sufficient to make L-type sensilla responsive to the bitter chemicals LOB, BER and DEN.
The expression of Gr59cUAS.cUa under the control of Scer\GAL4Gr33a-GAL4 in Gr59c1 mutants rescues their decreased I-a sensilla responsiveness to the bitter chemicals LOB, BER and DEN, and even induces hyper-responsiveness to LOB, BER and DEN in I-b, S-a and S-b sensilla.
Gr32aUAS.cSa, Gr59cUAS.cUa, Gr66aUAS.Tag:MYC, Scer\GAL4Gr64f.9.7 has abnormal taste perception | adult stage phenotype, non-suppressible by Df(3L)ΔGr64af
Gr32aUAS.cSa, Gr59cUAS.cUa, Gr66aUAS.Tag:MYC, Scer\GAL4Gr64f.9.7 has abnormal neurophysiology | adult stage phenotype, non-suppressible by Df(3L)ΔGr64af
Gr59cUAS.cUa/Scer\GAL4Gr33a-GAL4 is a suppressor of abnormal taste perception | adult stage phenotype of Gr22eLL05566
Gr59cUAS.cUa/Scer\GAL4Gr33a-GAL4 is a suppressor of abnormal neurophysiology | adult stage phenotype of Gr22eLL05566
Gr22eLL05566, Gr59cUAS.cUa, Scer\GAL4Gr33a-GAL4 has abnormal neurophysiology | adult stage phenotype
Gr22eLL05566, Gr59cUAS.cUa, Scer\GAL4Gr33a-GAL4 has abnormal taste perception | adult stage phenotype
Gr32aUAS.cSa, Gr59cUAS.cUa, Gr66aUAS.Tag:MYC, Scer\GAL4Gr64f.9.7 has abnormal neurophysiology | adult stage phenotype
Gr32aUAS.cSa, Gr59cUAS.cUa, Gr66aUAS.Tag:MYC, Scer\GAL4Gr64f.9.7 has large labellar taste bristle phenotype, non-suppressible by Df(3L)ΔGr64af
Gr59cUAS.cUa/Scer\GAL4Gr33a-GAL4 is a suppressor of short labellar taste bristle phenotype of Gr22eLL05566
Gr22eLL05566, Gr59cUAS.cUa, Scer\GAL4Gr33a-GAL4 has short labellar taste bristle phenotype
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 expression of Gr59cUAS.cUa under the control of Scer\GAL4Gr33a-GAL4 in Gr22eLL05566 mutants rescues their decreased S-b sensilla responsiveness to LOB, BER, DEN and STR, and even induces hyper-responsiveness to LOB, BER, DEN in both S-a and S-b sensilla, and ectopic responsiveness to LOB, BER and DEN in I-b sensilla, but does not have an effect on responsiveness in I-a sensilla.
