LmigOR 1 and LmigOR 2 expressed in ORNs housed by basiconic sensilla. a–b, Basiconic sensillum housed ORNs expressing LmigOR1 (a) and LmigOR2 (b). c–e, The expression of LmigOR1 and LmigOR2 in distinct subset of antennal ORNs was verified on consecutive sections (c–d) and by two-color in situ hybridization (e). Fluorescent signals were visualized using detection systems indicating LmigOR1-labelled neurons by green fluorescence and LmigOR2 positive cells by red fuorescence (e). Arrowheads denote antennal cells expressing LmigOR1 (a, c, e) and LmigOR2 (b, d, e). Ba: basiconic sensillum. Scale bar: a, b, e: 20 μm; c, d: 50 μm.
