(A) The strategy for Cre-based conditional pdfr-1 rescue 41. (B-G) QCIs for hermaphrodites carrying a conditional pdfr-1 transgene with the indicated pdfr-1 genotypes (+, wild-type; −, mutant) without or with nCre transgenes expressed pan-neuronally (“Neur::nCre”) (B), in muscle (“Musc::nCre”) (C), in a set of interneurons where pdfr-1 regulates motor state 41 (“tmg::nCre”) (D), in sensory neurons (“Sens::nCre”) (E), and in AIA and neurons expressing nmr-1 (“AIA+nmr-1::nCre”) (F, G), on T1 (B-F) or T3 (G) food.
