OCR-2 and OSM-9 contribute to the Tav response in the FLP neurons in the head and in the PHC neurons in the tail of C. elegans.
(A), (B) The head and tail Tav of osm-9 and ocr single and double mutants are shown. (C) The defective Tav response in the head of the ocr-2 osm-9 double mutant was rescued by the expression of ocr-2 and/or osm-9 full length genomic DNA as well as by expression of their respective cDNAs under the control of the mec-3 promoter. (D) The expression of either ocr-2 or osm-9 full-length genomic DNA was sufficient for at least partial rescue of the defective Tav response in the tail of the ocr-2 osm-9 double mutant. (*P<0.01; **P<0.001, n>80). Error bars indicate SD.
