FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
TrpA1unspecified mutants exhibit normal basal firing in class IV dendritic arborization neurons, but no light-induced firing increase.
Using MARCM clonal analysis, individual class IV dendritic arborization neurons lacking TrpA1 do not exhibit a response to light, and display a significant reduction in light-induced firing of the heterozygous class IV dendritic arborization neurons.
TrpA1unspecified has abnormal sensory perception phenotype, enhanceable by Gr28bMB03888/Gr28b[+]
TrpA1[+]/TrpA1unspecified is an enhancer of abnormal sensory perception phenotype of Gr28bMB03888
Transheterozygotes carrying one mutant allele of TrpA1unspecified and one copy of Gr28bMB03888 exhibit a reduced light response, suggesting that Gr28b and TrpA1 function in the same phototransduction pathway.
